The LTBP program's framework has two components: program management and technical execution.
The LTBP program was created as a 20-year research effort, with funding authorized for fiscal year (FY) 2006 through FY 2009.
For the LTBP program, consideration will be given to selecting bridges for study by groups based on performance characteristics that may include physical conditions and traffic and structural capacities.
FHWA envisions that the LTBP program will help foster technology development and integration.
FHWA will develop and document the protocols to ensure uniformity within the LTBP program and with the hope that they become standards for all future inspection and evaluation programs for infrastructure performance.
