LTBP Community

To succeed, the Long-Term Bridge Performance (LTBP) Program must establish strong partnerships with the State transportation departments that own bridges, consultants who design and inspect bridges, industries that supply the materials for bridges, and academics who provide innovative technologies for use on bridges. The LTBP Program staff has been working to strengthen these partnerships through various means of which some are discussed below.

State Coordinators

On a regular basis, the LTBP Program staff holds web meetings with the LTBP State Coordinators. During these meetings, the LTBP Team provided program updates and seeks stakeholders feedback.

The LTBP Program State Coordinator is a bridge engineer selected by his or her State transportation department to be their representative to support the Program. There are 52 State Coordinators—one for each State transportation department, including the Commonwealth of Puerto Rico and the District of Columbia. Feedback from the state coordinators include the following:

  • Documentation on the selected bridges, maintenance data, etc.
  • Access to the bridges for assessment.
  • Coordination of maintenance of traffic during field data gathering.
  • Review and revisions to protocols and articles.

TRB LTIP Advisory Committee

The charge to this TRB committee is to “advise the Federal Highway Administration (FHWA) Infrastructure Research and Development (R&D) Program regarding priorities in terms of the technical tools and products that State departments of transportation need to maintain and improve the performance of their pavements, bridges, and other structures.” The committee was established to provide an ongoing review of the LTIP based on annual meetings with FHWA staff and stakeholders.

The committee’s findings and recommendations strengthen awareness and support of the LTIP moving forward. Two TRB Expert Technical Groups meet multiple times annually in person and via web meetings to review LTIP programs including the LTBP program.
