Final rule.

The FHWA is revising its regulations relating to project authorization and agreements and the effect on obligations of Federal- aid highway funds under these requirements. The changes in this rulemaking will assist the States and the FHWA in monitoring Federal- aid highway projects and provide greater assurance that the Federal funds obligated reflect the current estimated cost of the project. In the event that Federal funds are de-obligated as a result of these changes, those funds may then be obligated for new or other active projects needing additional funding to the extent permitted by law.
