FEDERAL ITEM 5A - RECORD TYPE – X (1)
INVENTORY – ROADS
ON_UNDER
TABLE - ROADWAY

There are two types of National Bridge Inventory records: "on" and "under." Code the first digit
(leftmost) using one of the following codes:
Code
1
2
A through Z

Description
Route carried "on" the structure
Single route goes "under" the structure
Multiple routes go "under" the structure

A signifies the first of multiple routes under the structure.
B signifies the second of multiple routes under the structure.
Z signifies 26 routes under the structure.
"On" signifies that the inventory route is carried "on" the structure. Each bridge structure carrying
highway traffic must have a record identified with a type code = 1 (numeric). All of the NBI data items
must be coded, unless specifically excepted, with respect to the structure and the inventory route "on"
it.
"Under" signifies that the inventory route goes "under" the structure. If an inventory route beneath the
structure is on a Federal-aid highway, is a STRAHNET route or connector or is otherwise important, a
record must be coded to identify it. The type code must be 2 or an alphabetic letter A through Z.
Code 2 for a single route under the structure. If 2 or more routes go under a structure on separate
roadways, the code of 2 shall not be used. Code A, B, C, D, etc. consecutively for multiple routes on
separate roadways under the same structure. STRAHNET routes shall be listed first. When this Item
is coded 2 or A through Z, only the following items must be coded: Items 1, 3-11, 16, 17, 19, 20, 2630, 42, 43, 47-49, 100-104, 109 and 110. All other items are to remain blank.
Virginia Note: Overlapping under routes (single roadways carrying multiple routes) typically use only
one under record. However, some districts have elected to use a different record for
each route.
It cannot be overemphasized that all route-oriented data must agree with the coding as to whether the
inventory route is "on" or "under" the structure.
Tunnels shall be coded only as an "under" record; that is, they shall not be coded as a structure
carrying highway traffic.
There are situations of a route "under" a structure, where the structure does not carry a highway, but
may carry a railroad, pedestrian traffic, or even a building. These are coded the same as any other
"under" record and no "on" record shall be coded.

FEDERAL ITEM 5D - ROUTE NUMBER – XXXXX (5)
INVENTORY – ROADS
ROUTENUM
TABLE - ROADWAY

Code the route number of the inventory route in the next 5 positions. This value shall be right justified
in the field with leading zeros filled in. (See examples listed later.)
If concurrent routes are of the same hierarchy level, denoted by the route signing prefix, the lowest
numbered route shall be coded. Code 00000 for bridges on roads without route numbers.
Virginia Note: Since "Non-Highway On" records have Item 5A coded 2, "Non-Highway On" records
should have Item 5D "Route Number" coded as the route that passes under the
structure.
Virginia Note: A Footbridge, a structure which carries pedestrian traffic over something other than a
highway, will have Item 5A coded 1 and should have Item 5D "Route Number" coded
as the route which passes adjacent to or nearest the structure.
FEDERAL ITEM 5E - DIRECTIONAL SUFFIX - X (1)
INVENTORY – ROADS

It is required that the official structure number be recorded. It is not necessary to code this number
according to an arbitrary national standard. Each agency should code the structure number according
to its own internal processing procedures. When recording and coding for this item and following
items, any structure or structures with a closed median should be considered as one structure, not
two. Closed medians may have either mountable or non-mountable curbs or barriers.
The structure number must be unique for each bridge within the State, and once established should
preferably never change for the life of the bridge. If it is essential that structure number(s) must be
changed, all 15 digits are to be filled. For any structure number changes, a complete cross reference
of corresponding "old" and "new" numbers must be provided to the FHWA Bridge Division. The cross
reference shall include both a computer tape or diskette and a printed listing in the FHWA required

the beginning of the structure (i.e. the lowest kilometer/mile point on the bridge). When the LRS
Inventory Route goes under the structure (Item 5A coded 2 or A-Z), then code the kilometer/mile point
on the underpassing route where the structure id first encountered.
Code all zeros in this field for all records where kilometer/mile points are not provided. Kilometer/mile

The LRS inventory route number can be alphanumeric, but must not contain blanks. The LRS
inventory route number is not necessarily the same as that posted along the roadway, but is a number
used to uniquely identify a route within at least a county and perhaps throughout the State.
The subroute number is a number that uniquely identifies portions of an inventory route sections
where duplicate kilometerpoints occur. These subroute numbers, if they exist, are identified in the

The reason for the increased precision is to facilitate the use of Global Positioning System (GPS) data
directly into this item. The increased precision is not currently mandatory and, if GPS readings are not
available, the current measuring methods and level of precision may continue to be used. The
minimum precision should be to the nearest minute, but the preferred precision is to the nearest
hundredth of a second using GPS methods.
For bridges on STRAHNET and STRAHNET Connector highways and on the NHS, record and code
the latitude of each in degrees, minutes and seconds to the nearest hundredth of a second. The point
of the coordinate may be the beginning of the bridge in the direction of the inventory or any other
consistent point of reference on the bridge that is compatible with the LRS. If the bridge is not on a
STRAHNET highway or the NHS, a code of all zeros is acceptable, but it is preferable to code the

If a ground level bypass is available at the structure site for the inventory route, record and code the

If the bridge is one of twin bridges and is not at an interchange, code 01 where the other twin bridge
can be used as a temporary bypass with a reasonable amount of crossover grading. In other cases,
indicate the actual length to the nearest mile of the detour length. The detour length should represent
the total additional travel for a vehicle that would result from closing the bridge. The factor to
consider when determining if a bypass is available at the site is the potential for moving vehicles,
including military vehicles, around the structure. This is particularly true when the structure is in an
interchange. For instance, a bypass likely would be available in the case of diamond interchanges,
interchanges where there are service roads available, or other interchanges where the positioning and
layout of the ramps is such that they could be used without difficulty to get around the structure. Code
99 for 99 mile or more.
The detour route will be established following allowable criteria determined by the governing authority.
(Some authorities will not allow a designated detour over a road or bridge of lesser "quality.")
Virginia Note: The route must not contain structures with a lower posting than the subject bridge and
must be a comparable type of road.

Bridge inspection shall include the recording of information on the following traffic features so that the

(36A)

(36C)

(36D)

Bridge railings:
Some factors that affect the proper functioning of bridge railing are height, material,
strength, and geometric features. Railings must be capable of smoothly redirecting
an impacting vehicle. Bridge railings should be evaluated using the current
AASHTO Standard Specifications for Highway Bridges, which calls for railings to
meet specific geometric criteria and to resist specified static loads without
exceeding the allowable stresses in their elements. Bridge railing should be crash
tested per FHWA policy. Railings that meet these criteria and loading conditions
are considered acceptable. Other railings that have been successfully crash
tested are considered acceptable even though they may not meet the static loading
analysis and geometric requirements. Acceptable guidelines for bridge railing
design and testing are also found in the AASHTO Guide Specifications for Bridge
Railings 1989. Additional guidance for testing is found in National Cooperative
Highway Research Program - Report 350 Recommended Procedures for the
Safety Performance Evaluation of Highway Features 1993.
Transitions:
The transition from approach guardrail to bridge railing requires that the approach
guardrail be firmly attached to the bridge railing. It also requires that the approach
guardrail be gradually stiffened as it comes closer to the bridge railing. The ends
of curbs and safety walks need to be gradually tapered out or shielded.
Approach guardrail:
The structural adequacy and compatibility of approach guardrail with transition
designs should be determined. Rarely does the need for a barrier stop at the end
of a bridge. Thus, an approach guardrail with adequate length and structural
qualities to shield motorists form the hazards at the bridge site needs to be
installed. In addition to being capable of safely redirecting an impacting vehicle,
the approach guardrail must also facilitate a transition to the bridge railing that will
not cause snagging or pocketing of an impacting vehicle. Acceptable guardrail
design suggestions are contained in the AASHTO Roadside Design Guide and
subsequent FHWA or AASHTO guidelines.
Approach guardrail ends:
As with guardrail ends in general, the ends of approach guardrails to bridge should
be flared, buried, made breakaway, or shielded. Design treatment of guardrail
ends is given in the AASHTO Roadside Design Guide.

ROADWIDTH
TABLE - ROADWAY

The information to be recorded is the most restrictive minimum distance between curbs or rails on the
structure roadway. For structures with closed medians and usually for double decked structures,
coded data will be the sum of the most restrictive minimum distances for all roadways carried by the
structure except as noted below. The data recorded for this item must be compatible with other
related route and bridge data (i.e. Items 28, 29, 32, etc.). The measurement should be exclusive of
flared areas for ramps. A 4-digit number should be used to represent the distance to the nearest tenth
of a foot.
Where traffic runs directly on the top slab (or wearing surface) of a culvert-type structure, e.g. an R/C
box without fill, code the actual roadway width (curb-to-curb or rail-to-rail). This will also apply where
the fill is minimal and headwalls or parapets affect the flow of traffic.
Where the roadway is on fill carried across a structure and the headwalls or parapets do not affect the
flow of traffic, code 0000. This is considered proper inasmuch as a filled section simply maintains the
roadway cross-section. However, for sidehill viaduct structures code the actual full curb-to-curb
roadway width. See figure in Federal Coding Guide Appendix D.
NOTE: Raised or non-mountable medians, open medians, and barrier widths are to be
excluded from the summation along with barrier-protected bicycle and equestrian lanes.

examples refer to Federal Items 50, 51 and 52)
Where traffic runs directly on the top slab (or wearing surface) of the culvert (e.g., an R/C box without
fill) coded the actual width (out-to-out). This will also apply where the fill is minimal and the culvert
headwalls affect the flow of traffic. However, for sidehill viaduct structures code the actual out-to-out
structure width. See figure in Federal Coding Guide Appendix D.
Where the roadway is on a fill carried across a pipe or box culvert and the culvert headwalls do not

The information to be recorded for this item is the actual minimum vertical clearance over the bridge
roadway, including shoulders, to any superstructure restriction, rounded down to the nearest inch. For
double decked structures code the minimum, regardless whether it is pertaining to the top or bottom
deck. Coding of actual clearances between 100 feet and 300 feet to an exact measurement is
optional (see Virginia Note below). When no superstructure restriction exists above the bridge
roadway, code 9999. A 4-digit number should be coded to represent feet and inches.
Virginia Note: When no restriction exists above the bridge roadway, or when a restriction is 100 feet
or greater code 9999. The restriction should be measured to any item that creates a

Virginia Note: When a restriction is 100 feet or greater code 9912. For clearances less than or equal
to 25 feet the clearance should be measured and recorded. For clearances between
25 feet and 100 feet the clearance should be measured directly or estimated from the
plans and recorded.
Where to measure
The traveled part of the roadway and/or the travel lane will include the width of traffic
lanes and the widths of shoulders where shoulders are defined as follows:
Shoulders must be constructed and normally maintained flush
with the adjacent traffic lane, and must be structurally adequate
for all weather and traffic conditions consistent with the facility
carried.
Unstabilized grass or dirt, with no base course, flush with and
beside the traffic lane is not to be considered a shoulder.
Therefore, measurements for all vertical clearances should be checked across all
portions of the 'traveled part of the roadway' and/or 'travel lane', as defined above, and
the minimum clearance recorded for the item which is being checked (Federal Item 10,
Federal Item 53, Federal Item 54, State Item 36 and State Item 37). Of course, if edge
of pavement is behind the face of a guardrail then stop at the face of the guardrail.
When on a bridge deck measurements will be checked from face of parapet/railing to
face of parapet/railing. I have checked Manual 90, the 'Recording and Coding Guide
for the Structure Inventory and Appraisal of the Nation's Bridges', the 'Manual for
Condition Evaluation of Bridges' and I have checked with Claude Napier concerning
this. He agrees with this definition and method.

1 to 1 or 2 to 1). The clearance measurements to be recorded will be the minimum after measuring
the clearance in both directions of travel. In the case of a dual highway this would mean the outside
clearances of both roadways should be measured and the smaller distance recorded and coded.
If two related features are below the bridge, measure both and record the lesser of the 2. An

GENERAL CONDITION RATINGS
In order to promote uniformity between bridge inspectors, these guidelines will be used to rate and
code items 58, 59, 60, 61 and 62.
Condition ratings are used to describe the existing, in-place bridge as compared to the as-built
condition. Evaluation is for the materials related, physical condition of the deck, superstructure and
substructure components of a bridge. The condition evaluation of channels and channel protection
and culverts is also included. Condition codes are properly used when they provide an overall
characterization of the general condition of the entire component being rated. Conversely, they are
improperly used if they attempt to describe localized or nominally occurring instances of deterioration
or disrepair. Correct assignment of a condition code must, therefore, consider both the severity of the
deterioration or disrepair and the extent to which it is widespread throughout the component being
rated.
The load carrying capacity will not be used in evaluating condition items. The fact that a bridge was
designed for less than current legal loads and may be posted shall have no influence upon condition
ratings.
Portions of bridges that are being supported or strengthened by temporary members will be rated
based on their actual condition; that is, the temporary members are not considered in the rating of the
item. (See Item 103 - Temporary Structure Designation for the definition of a temporary bridge.)
Completed bridges not yet opened to traffic, if rated, shall be coded as if open to traffic.
The following general condition ratings shall be used as a guide in evaluating Items 58, 59, 60, 61 and
62:

Concrete decks should be inspected for cracking, scaling, spalling, leaching, chloride contamination,
potholing, delamination, and full or partial depth failures. Steel grid decks should be inspected for
broken welds, broken grids, section loss, and growth of filled grids from corrosion. Timber decks
should be inspected for splitting, crushing, fastener failure, and deterioration from rot.
The condition of the wearing surface/protective system, joints, expansion device, curbs, sidewalks,
parapets, fascias, bridge rail, and scuppers shall not be considered in the overall deck evaluation.
However, their condition should be noted on the inspection form.
Decks integral with the superstructure will be rated as a deck only and not how they may influence the
superstructure rating (for example, rigid frame, slab, deck girder or T-beam, void slab, box girder, etc.).
Similarly, the superstructure of an integral deck-type bridge will not influence the deck rating.

The condition of bearings, joints, paint system, etc. shall not be included in this rating, except in
extreme situations, but should be noted on the inspection form.
On bridges where the deck is integral with the superstructure, the superstructure condition rating may
be affected by the deck condition. The resultant superstructure condition rating may be lower than the
deck condition rating where the girders have deteriorated or been damaged. Fracture critical

This capacity rating, referred to as the operating, will result in the absolute maximum permissible load
level to which the structure may be subjected for the vehicle type used in the rating. Code the
operating rating as a 3-digit code.
(SEE ‘MISC’ FOR HANDLING OF PIPES AND CULVERTS.)
Virginia Note: The newest Federal coding guide uses the only MS loading to determine operating
rating. This is the metric equivalent of the HS loading. We will continue to use the HS
loading to determine the operating rating and will convert these electronically to the MS
equivalent when providing our annual report to the federal government. Since only one
vehicle is now allowed to determine the operating rating we will report the loading as
before and use a leading 0 where the type of vehicle would normally be coded. It
should be emphasized that for HS loading, the total weight in tons of the entire vehicle
should be coded; that is HS20 shall be coded 036 even though the HS20 lane loading
FEDERAL and STATE ITEM NUMBER ORDER

Page 33

October 8, 2009

controls and is used to determine the rating. Likewise HS10 shall be coded 018. The
requirement of only using an equivalent HS loading was phased in over a 5-year period.
Therefore, all National Bridge Inventory updates in 1993 were to be report the
operating and inventory ratings in an equivalent HS loading regardless of the loading
used to calculate the ratings.
The AASHTO Manual for Condition Evaluation of Bridges provides a choice of load rating methods,
such as the new load and resistance factor (LRFR) rating method, in addition to the traditional
allowable stress (AS) and load factor (LF) methods. Of the three rating methods, the LF method is the
most suitable for use as a national standard, therefore the FHWA has chosen the LF method as the
standard for computing inventory and operating ratings reported to the NBI. The highway agencies
may, however, elect to use LF, AS or LRFD to establish load limits for purposes of load posting.
If the bridge will not carry a minimum of 3 tons of live load, the operating rating shall be coded '000';
and consistent with the direction of the AASHTO Manual, it shall be closed.
The use or presence of a temporary bridge requires special consideration in coding. In such cases,
since there is no permanent bridge, Items 64 and 66 should be coded as 000 even though the
temporary structure is rated for as much as full legal load.
A bridge shored up or repaired on a temporary basis is considered a temporary bridge and the
inventory and operating rating should be coded as if the temporary shoring were not in place. See
Item 103 - Temporary Structure Designation for definition of a temporary bridge.

This item is calculated by the program and need not be coded by the bridge inspector.
The following specifications are used by the program:
For structures other than culverts, the lowest of the codes obtained from Item 59 Superstructure, Item 60 - Substructure, or Table 1 is used.
For culverts, the lowest of the codes obtained from Item 62 - Culverts, or Table 1 should
generally be used.
If Item 59, Item 60 or Item 62 is coded 1, then Item 67 is equal to zero (0), regardless of
whether the structure is actually closed. However, if the structure is closed, it does not mean
that this value is zero (0) unless the overall condition and appraisal ratings indicate that a code
of 0 is appropriate.

DECKGEOM
TABLE - INSPEVNT

This item is calculated by the Program and need not be coded by the bridge inspector.
The overall rating for deck geometry includes two evaluations:
• The curb-to-curb or face-to-face of rail bridge width using Table 2A, B, C, or D and
• The minimum vertical clearance over the bridge roadway using Table 2E.
The lower of the codes obtained from these tables shall be used. When an individual table lists
several deck geometry rating codes for the same roadway width under a specific ADT, use the lower
code. (For example, Table 2A lists deck geometry rating codes 6, 7 and 8 for a 44-foot roadway width
and an ADT of >5000. Use the code of 6.) For values between those listed in the tables, the lower
code is used.
The curb-to-curb or face-to-face of rail dimension shall be taken from Item 51 - Bridge Roadway
Width, Curb-to-Curb. Item 53 - Minimum Vertical Clearance Over Bridge Roadway shall be used to
evaluate the vertical clearance.
The values provide in the tables are for rating purposes only. Current design standards must be used
for structure design or rehabilitation.

POSTING
TABLE - BRIDGE

The National Bridge Inspection Standards require the posting of load limits only if the maximum legal
load configurations in the State exceed the load permitted under the operating rating. If the load
capacity at the operating rating is such that posting is required, this item shall be coded 4 or less. If no
posting is required at the operating rating, this item shall be coded 5.
This item evaluates the load capacity of a bridge in comparison to the State legal load. It differs from
Item 67 - Structural Evaluation in that Item 67 uses Item 66 - Inventory Rating, while the bridge posting
requirement is based on Item 64 - Operating Rating.
Although posting a bridge for load-carrying capacity is required only when the maximum legal load
exceeds the operating rating, highway agencies may choose to post at a lower level. This posting
practice may appear to produce conflicting coding when Item 41 - Structure Open, Posted or Closed to
Traffic is coded to show the bridge as actually posted at the site and Item 70 - Bridge Posting is coded

as bridge posting is not required. Since different criteria are used for coding these 2 items, this coding
is acceptable and correct when the highway agency elects to post at less than the operating rating.
Item 70 shall be coded 4 or less only if the legal load of the State exceeds that permitted under the
operating rating.
The use or presence of a temporary bridge affects the coding. The actual operating rating of the
temporary bridge should be used to determine this item. However the highway agency may choose to
post at a lower level. This also applies to bridges shored up or repaired on a temporary basis.

Virginia Note: Virginia has elected to post its structures using the loads produced by the Virginia legal
vehicles. These are the three axle - 27-ton vehicle and the 5 axle - 40-ton vehicle. Therefore, for Item
70, we must figure the capacity of the Virginia legal vehicles at the operating stress level and compare
whether the structure would be posted at that level.
Example 1:
The 27-ton Virginia legal vehicle produces a capacity of 23 tons at the operating stress level.
Since this Virginia legal vehicle is a 27-ton vehicle, we compare the 23-ton capacity at the
operating stress level to the 27-ton vehicle, the difference is 4 tons. 4/27 = .148 which is
14.8%, then Item 70 would be coded a 3, since a code of 3 is from 10.0 - 19.9% below legal
loads.
Example 2:
The 27-ton Virginia legal vehicle produces a capacity of 28 tons at operating stress level.
Since this Virginia legal vehicle is a 27 ton vehicle, we compare the 28 ton capacity at the
operating stress level to the 27 ton vehicle, the capacity is above the legal load of 27 tons, then
Item 70 would be coded a 5, since a code of 5 is for capacities at the operating stress level
equal to or above legal loads.
NOTE: The structure used in Example 2 may be posted since Virginia figures the posting capacity at
a stress level below operating stress level for other than concrete spans. The posting capacity
(whatever the posting level) that Virginia uses is not considered in the coding of Item 70. Therefore,
the structure used in Example 2 would still have a coding of 5 for Item 70. In the examples only the
27-ton vehicle was cited, it could be that the 40-ton vehicle would be below legal limit even though the
27-ton vehicle was above legal limit. Therefore, both vehicles must be checked.

EDIT CHECK
If Item 70 is coded < 5 then one of items 58 - 62 must be coded 3 or less. However, keep
in mind that this item uses OPERATING stress to determine posting. That means that
some structures may be posted and yet be coded 5 (since we use a stress less than
operating to determine posting). A review flag occurs if Item 27 is younger than 4 years old
or equal to current year and any one Item 58 through Item 62 or any one Item 67 through
Item 72 is < 5 and not N. A warning is issued if any one of Items 41, 58, 59, 60, 62, 67, 68,

APPRALIGN
TABLE - INSPEVNT

Code the rating based on the adequacy of the approach roadway alignment. This item identifies those
bridges that do not function properly or adequately due to the alignment of the approaches. It is not
intended that the approach roadway alignment be compared to current standards but rather to the
existing highway alignment. This concept differs from other appraisal evaluations. The establishment
of set criteria to be used at all bridge sites is not appropriate for this item. The basic criteria is how the
alignment of the roadway approaches to the bridge relate to the general highway alignment for the
section of highway the bridge is on.

FEDERAL and STATE ITEM NUMBER ORDER

Page 46

October 8, 2009

The individual structure shall be rated in accordance with the general appraisal rating guide in lieu of
specific design values. Approach roadway alignment will be rated intolerable (a code of 3 or less) only
if the horizontal or vertical curvature requires a substantial reduction in the vehicle operating speed
from that on the highway section. A very minor speed reduction will be rated a 6, and when a speed
reduction is not required, the appraisal code will be an 8. Additional codes may be selected between
these general values.
For examples, if the highway section requires a substantial speed reduction due to vertical or
horizontal alignment, and the roadway approach to the bridge requires only a very minor additional
speed reduction at the bridge, the appropriate code would be a 6. This concept shall be used at each
bridge site.
Speed reductions necessary because of structure width and not alignment shall not be considered in
evaluating this item.

EXAMPLES:
Code
311
A bridge is to be replaced by contract because it has deteriorated to the point that
it can no longer carry legal loads. The same code should be used if the bridge is
replaced because it is now too narrow or the original design was too light to
accommodate today's legal loads.
321
A bridge is to be replaced because the roadway must be straightened to eliminate
a dangerous curve. The work will be done by contract.
331
A bridge is to be widened to increase shoulder width or the number of traffic lanes.
Existing deck is in good condition and will be incorporated as is into the new
structure. The work is to be done by contract.
331
A culvert is to be extended by contract to accommodate additional roadway width
as part of a reconstruction contract to improve the safety of the adjacent slopes.
341
A deck is to be rehabilitated and the bridge widened to proved a full 12-foot
shoulder. The existing shoulder is only 7.87 inches wide and an extra line of
girders with appropriate substructure widening must be added. The work will be
done by contract.
352
A bridge superstructure and substructure are to be rehabilitated by State forces to
increase the bridge's load capacity.
361
A bridge deck is to be rehabilitated by contract and a safety curb to be removed
which results in incidental widening of 2 feet.
371
A bridge deck is to be replaced by contract and the deck cantilever overhang
extended 2 feet, which is the maximum that can be done without adding another
line of stringers or girders to the superstructure.

TABLE - BRIDGE

Code a 6-digit number that represents the length of the proposed bridge improvement to the nearest
foot. For replacement or rehabilitation of the entire bridge, the length should be back to back of
backwalls of abutments or from pavement notch to pavement notch. For replacement or rehabilitation
of only part of the structure, use the length of the portion to be improved.
This item must be coded for bridges eligible for the Highway Bridge Replacement And Rehabilitation
Program. It may be coded for other bridges at the option of the highway agency.
For culvert improvements, use the proposed length measured along the centerline of the barrel
regardless of the depth below grade. The measurement should be made between the inside faces of
the top parapet or edge-stiffening beam of the top slab.
EXAMPLES:
Length of Structure Improvement

Code
250 feet 000250
1,200 feet 001200
12,345 feet 012345

For substructure or channel work only, code the length of superstructure over or supported by, the
substructure or channel.
Typically, a replacement bridge is longer than the existing bridge. Nationwide averages for the
increase in bridge length with replacement as a function of the existing length are given in the
following figures. The length-expansion factors represent data for the years 1981 to 1985. Where
site-specific data is lacking, these factors are suggested for estimating the length of replacement
bridges. For exceedingly long bridges (i.e., 1000 feet or more) the length-expansion factor
approaches 1.0.
(For a detail example of Item 75 refer to the Federal Coding Guide)
EDIT CHECK
If the bridge is structurally deficient and/or functionally obsolete (see appendix for definitions)

this is the way the Feds want us to report this data, it is NOT the way we collect our data). This
inspection date may be different from those recorded in Item 93 - Critical Feature Inspection Date.
Code a 4-digit number to represent the month and year. The number of the month should be coded in
the first 2 digits with leading zeros as required and the last 2 digits of the year coded as the third and

FEDERAL ITEM 91 - DESIGNATED INSPECTION FREQUENCY - XX (2)
SCHEDULE
BRINSPFREQ
TABLE - INSPEVNT

Code 2 digits to represent the number of months between designated inspections of the structure.
Leading zeros shall be coded. The individual in charge of the inspection program is responsible for
determining the inspection interval. For posted, understrength bridges, this interval should be
substantially less than the 24-month standard. The designated inspection interval could vary form
inspection to inspection depending on the condition of the bridge at the time of inspection.
EXAMPLES:
Code
01
24

Posted bridge with heavy truck traffic and questionable structural details
which is designated to be inspected each month
Bridge is scheduled to be inspected every 24 months

Only the following frequencies are allowed: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 24, 48 and 60.
It should be noted that bridges require special non-scheduled inspections after unusual physical
traumas such as floods, earthquakes, fires or collisions. These special inspections may range from a
very brief visual examination to a detailed in-depth evaluation depending upon the nature of the
trauma. For example, when an errant vehicle strikes a substructure unit (pier or abutment), in most
cases only a visual examination of the bridge is necessary. After major collisions or earthquakes, indepth inspections may be warranted as directed by the engineer in overall charge of the program.
After and during severe floods, the stability of the substructure of bridges may have to be determined
by probing, underwater sensors or other appropriate measures. Underwater inspection by divers may
be required for some scour critical bridges immediately after floods. See Item 113 - Scour Critical
Bridges.
EDIT CHECK
Item 91 must be between 00 and 48 inclusive.
A warning is issued if Item 91 is > 24 months.

For a bridge to be defined as reconstructed, the type of work performed, whether or not it meets
current minimum standards, must have been eligible for funding under any of the Federal-aid funding
categories. The eligibility criteria would apply to the work performed regardless of whether all State or
local funds or Federal-aid funds were used.
Some types of eligible work not to be considered as reconstruction are listed:
- Safety feature replacement or upgrading (for example, bridge rail, approach guardrail
or impact attenuators).
- Painting of structural steel.
- Overlay of bridge deck as part of a larger highway surfacing project (for example,
overlay carried across bridge deck for surface uniformity without additional bridge
work).
- Utility work.
- Emergency repair to restore structural integrity to the previous status following an
accident.
- Retrofitting to correct a deficiency that does not substantially alter physical geometry or
increase the load-carrying capacity.
- Work performed to keep a bridge operational while plans for complete rehabilitation or

Virginia Note: For something to be called a wearing surface, it must be placed separately from the
time the deck is placed. This is the first and most important test. Therefore,
monolithically place concrete (the ½” that designers call a wearing surface) is not a
wearing surface. The following are wearing surfaces: asphaltic concrete overlays,
latex overlays, epoxy overlays or overlays of A-4 concretes. There are others not
mentioned.
Now for some exceptions, remember, for something to be called a wearing surface, it
must be placed separately from the time the deck is placed. However, if an application
is placed separately from the time the deck is placed and if the designer and the
analyzer consider it in the capacity of the structure, it will not be considered an overlay.
Therefore, reinforced A-4 overlays (the concrete placed over prestressed deck panels,
etc.) are not wearing surfaces. They are part of the deck. While this is in conflict with
some of the wording of Manual 90, I believe the above definitions best suit Virginia’s
need for this information and will reduce or eliminate coding disparities. Mr. Claude
Napier of the FHWA approves of this definition.

FEDERAL ITEM 113 - SCOUR CRITICAL BRIDGES – X (1)
APPRAISAL – OTHER RATINGS
SCOURCRIT
TABLE - INSPEVNT

Use a single-digit code as indicated below to identify the current status of the bridge regarding its
vulnerability to scour. Evaluations shall be made by hydraulic/geotechnical/structural engineers. Guidance
on conducting a scour evaluation is included in the FHWA Technical Advisory T 5140.23 titled, "Evaluating
Scour at Bridges." Detailed engineering guidance is provided in the Hydraulic Engineering Circular 18 titled
"Evaluating Scour at Bridges." Whenever a rating factor of 2 or below is determined for this item, the rating
factor for Item 60 -- Substructure and other affected items (i.e., load ratings, superstructure rating) should
be revised to be consistent with the severity of observed scour and resultant damage to the bridge. A plan
of action will be developed for each scour critical bridge (see FHWA Technical Advisory T 5140.23, HEC
18 and HEC 23). A scour critical bridge is one with abutment or pier foundation rated as unstable due to (1)
observed scour at the bridge site (rating factor of 2, 1, or 0) or (2) a scour potential as determined from a
scour evaluation study (rating factor of 3). It is assumed that the coding of this item has been based on an
engineering evaluation, which includes consultation of the NBIS field inspection findings.

Description

Bridge not over waterway.

Bridge with ‘unknown’ foundation that has not been evaluated for scour. Until risk can be
determined, a plan of action should be developed and implemented to reduce the risk to
users from a bridge failure during and immediately after flood events.

Bridge over ‘tidal’ water that has not been evaluated for scour, but considered low risk.
Bridge will be monitored with regular inspection cycle and with appropriate underwater
inspections until an evaluation is performed. (‘Unknown’ foundations in ‘tidal’ waters should
be coded U.)

Bridge foundations (including piles) on dry land well above flood water elevations.

Bridge foundations determined to be stable for the assessed or calculated scour condition.
Scour is determined to be above top of footing (Example A) by assessment (i.e., bridge
foundations are on rock formations that have been determined to resist scour within the
service life of the bridge), by calculation or by installation of properly designed
countermeasures (see HEC 23).

Countermeasures have been installed to mitigate an existing problem with scour at an
existing bridge to reduce the risk of bridge failure during a flood event. Instructions
contained in a plan of action have been implemented to reduce the risk to users from a
bridge failure during or immediately after a flood event.

Scour calculation/evaluation has not been made. (Use only to describe case where bridge
has not yet been evaluated for scour potential.)

Bridge foundations determined to be stable for assessed or calculated scour condition.
Scour is determined to be within the limits of footing or piles (Example B) by assessment
(i.e., bridge foundations are on rock formations that have been determined to resist scour
within the service life of the bridge), by calculations or by installation of properly designed
countermeasures (see HEC 23).

Bridge foundations determined to be stable for assessed or calculated scour conditions; field
review indicates action is required to protect exposed foundations (see HEC 23).

Bridge is scour critical; bridge foundations determined to be unstable for assessed or
calculated scour conditions:
- Scour within limits of footing or piles. (Example B)
- Scour below spread-footing base or pile tips. (Example C)

Bridge is scour critical; field review indicates that extensive scour has occurred at bridge
foundations, which are determined to be unstable by:
- a comparison of calculated scour and observed scour during the bridge inspection, or
- an engineering evaluation of the observed scour condition reported by the bridge
inspector in Item 60.

Bridge is scour critical; field review indicates that failure of piers/abutments is imminent.
Bridge is closed to traffic. Failure is imminent based on:
- a comparison of calculated and observed scour during the bridge inspection, or
- an engineering evaluation of the observed scour condition reported by the bridge
inspector in Item 60.

Bridge is scour critical. Bridge has failed and is closed to traffic.
