A January 31, 2022 letter report from TRB's Committee for the Review of Federal Highway Administration (FHWA) Infrastructure R&D Program's Long-Term Infrastructure Program (LTIP) summarizes recent program progress, strategic issues, and committee recommendations for future actions. The program has produced some useful products and results over the past year and continued to improve user accessibility to data and information.

Although FHWA’s infrastructure research and development is considerably broader than the LTIP, the latter is the sole focus of this committee’s efforts. The LTIP collects long-term performance data on the condition of bridges and pavements that are valuable for guiding decisions regarding the maintenance, repair, and replacement of vital transportation infrastructure assets.
