RAIL BRIDGE MANAGEMENT PROGRAM The FRA established Federal safety requirements for railroad bridges in 2010 under 49 CFR Part 237. VTrans established a Rail Bridge Management Program in September 2012 in accordance with these regulations. The program is responsible for collecting and maintaining an inventory of rail bridges, their condition, and making recommendations on repairs, strengthening or replacement of components or entire structures. These regulations also mandate that annual safety inspections are performed for each bridge, and that all bridges have an initial determination of load capacity completed by September 2017.
There are 214 rail bridges on State-owned property. The State is responsible for 165 of those bridges, with the railroad operator responsible for the remaining 49 bridges through existing lease agreements.

VTrans Railroad Bridge Management Program
Rating Code Definitions The purpose of the rating system is to ensure consistency in classifying structures with an appropriate code and to provide a corrective reaction for the identified condition. The rating system attempts to provide an overall understanding of a structure’s condition and is based on an inspector applying appropriate condition rating codes. The following summarizes this relationship:
Key – Explanation of Double Letter Codes:
N/A Not Applicable
AA Continue to inspect structure on a one year cycle.
BB No rehabilitative measures are required for the next time the structure is to be inspected.
CC Structure’s component(s) can be treated effectively or improved with accelerated maintenance procedures and/or replacement of structural component(s) to extend service life.
DD Structure listed in long term rehabilitation program for rehabilitation within the next five to ten year period.
EE Structure listed in intermediate term rehabilitation program for rehabilitation within the next two to five year period.
FF Structure listed in short term rehabilitation program for rehabilitation within the next two year period. Requires periodic monitoring of identified structural concern(s).
GG Immediate rehabilitation necessary.
HH Structure has failed and is to remain out of service pending reconstruction.
Condition Rating Condition Description Implied Reaction Key H Hidden Not Applicable N/A N Not Applicable Not Applicable N/A 9 Excellent No Action AA 8 Very Good No Action AA 7 Good No Action AA 6 Satisfactory Improve Maintenance BB 5 Fair Periodic Maintenance CC 4 Poor Long Term Rehabilitation DD 3 Serious Intermediate Term Rehabilitation EE 2 Critical Short Term Rehabilitation FF 1 Failure Imminent Emergency Declaration GG 0 Structural Failure Replace Structure HH

STATEWIDE LOAD CAPACITY Load Capacity Analyses have been performed on 107 of our bridges.
17 Load Capacity Analsyes are scheduled to be completed by 6/30/15.
An additional 9 will be completed when construction of the programmed bridge project is completed.
The remaining 32 are required to be complete by September 2017.
Results from Annual Safety Inspections, or In-Depth Inspections, may require updated Load Capacity
