Long-Term Bridge Performance

InfoBridge

Public release of the InfoBridge web portal occurred in conjunction with the 2019 Transportation Research Board Annual Meeting. Data disseminated and displayed through InfoBridge include both data collected specifically for the LTBP Program and the National Bridge Inventory (NBI). The visualization capabilities provided in InfoBridge are highly beneficial to the States and other highway bridge owners as they work to manage bridge performance.

Status of LTBP Program

The LTBP Program is a long-term research effort, authorized by the U.S. Congress under the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) to collect high-quality bridge data from a representative sample of highway bridges nationwide that will help the bridge community to better understand bridge performance. This site contains information about the program including a discussion of the program objectives and bridge selection methodology (About), LTBP ProductsLTBP CommunityNondestructive Evaluation and Structural Health Monitoring as it relates to the Program, and an update on Pooled Fund Project TPF-5(283): The Influence of Vehicular Live Loads on Bridge Performance, and a listing of current LTBP Program Publications.
