Department of Transportation: Flexible Funding Within Federal Highway Programs

Pursuant to a congressional request, GAO determined the extent to which the states have used the funding flexibility available for the National Highway System, the Interstate Maintenance Program, and the Highway Bridge Replacement and Rehabilitation Program, focusing on: (1) comparing the actual funds transferred from the three major programs with the maximum funds that could have been transferred with and without the approval of the Secretary of Transportation; (2) the number of states transferring funds from each of the three major highway programs; and (3) the total amount of funds that can be used or transferred to the Surface Transportation Program (STP).
