All projects built with federal funds have an executed agreement between the Federal Highway Administration (FHWA) and TxDOT. One agreement provision requires maintenance of the completed project. For projects on the state highway system, TxDOT will normally perform the maintenance with state forces or through a contract with a private vendor. For projects off the state highway system, the LG must assure the project is maintained “satisfactorily.” Maintenance responsibilities are outlined in the advance funding agreement (AFA). of the LGPP Manual and contain more information on these two types of agreements. TxDOT and FHWA retain authority to periodically review federally funded projects and assess the LG’s efforts to maintain the project as designed.
