Federal-Aid Highways: FHWA Has Improved Its Risk Management Approach, but Needs to Improve Its Oversight of Project Costs

摘要

The federal-aid highway program provides about $33 billion a year to states for highway projects. The federal government provides funding for and oversees this program, while states largely choose and manage the projects. As requested, GAO reviewed the Federal Highway Administration's (FHWA) implementation of several requirements in the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU): (1) oversight of states using a risk management approach; (2) efforts to develop minimum standards for estimating project costs, and periodically evaluate states' cost estimating practices; and (3) reviews of states' financial management systems. GAO also reviewed FHWA's policy on presenting an estimate of financing costs in financial plans for major projects (i.e., projects estimated to cost over $500 million). GAO reviewed FHWA plans, risk assessments, reviews, and other documents; visited five FHWA field offices and reviewed financial management reviews in an additional five field offices; and interviewed FHWA officials.
