The INDOT Central Office Bridge Inspection & Inventory Section is the source for bridge inventory and inspection data for both state and county owned bridges in Indiana. The section oversees all aspects of the bridge inspection process to ensure the state and counties meet all federal regulations relating to the National Bridge Inspection Standards, (NBIS).

The state and counties must meet all the federal regulations including NBIS regulations, in order to remain eligible to receive federal bridge funds needed to conduct work on eligible bridges.

In addition, the section oversees all bridge inspectors’ qualifications & training, the Major Bridge Program, INDOT statewide inspection contracts, and INDOT’s underbridge inspection machines.


National Bridge Inspection Report (NBI)

The Central Office Bridge Inspection & Inventory Section is responsible for generating and submitting Indiana’s annual submission of bridge data to the Federal Highway Administration, (FHWA). The FHWA uses this data to maintain its National Bridge Inventory database, (NBI). Indiana’s NBI Data is submitted by April 1st each year and contains updated inspection and inventory information on all bridges. The information from this data submittal is used by the FHWA to determine sufficiency ratings, structural adequacy, and eligibility to use Federal Bridge Funds.

Inventory of Bridges Book

The Inventory of Bridges Book, or Bridge Log Book, was originally created around 1937. Its original purpose was to serve as a listing of all the roads in the state and identifying all bridges on those roads. In addition, it was meant to identify all bridges with posted weight limit restrictions, (the book has also been called the “Posted Bridge Book” at times). A final purpose of the book was to keep a record of contracted construction activities currently underway or completed.

A printed version of the book has been printed for general use at various frequencies over the years. The last paper version was printed in March 2005. Today, an electronic version is available using the Bridge Inspection Application System (BIAS). This version is updated daily. A paper work book is no longer available.

 

Major Bridge Program

The mission of the Major Bridge Program (MBP) is to provide for the inspection, maintenance, and replacement or construction of bridges that qualify as a major bridge. The MBP has the responsibility of completing this mission with fiscal restraint, while ensuring structural integrity, and public safety.

The MBP Protocols and Policies document summarizes the MBP policies and procedures for selecting Major Bridge projects. It includes the principles for selecting the scoring criteria and how the criteria are used to score projects. It also contains tables used to determine priorities of bridges and protocols on how the process will be conducted.
