In 1991, GAO raised concerns about the condition of Interstate highways and rising levels of congestion. The original purposes for the Interstate system were to provide for efficient long-distance travel, support defense, and connect metropolitan and industrial areas. Today, the most important role that the Interstates perform, other than supporting safe travel, is moving freight traffic across their states. The federal government provides funding for, and oversight of, the Interstate system while the states do most of the maintaining and planning for the future of the system. Combined federal and state spending on the Interstate System increased from $13.0 billion in 1992 to 16.2 billion in 2000. States are required to pay ten percent of the cost of an Interstate project; however, GAO found that the average nonfederal share of urban Interstate projects was 15 percent and 11 percent for rural projects. Interstate highways are in better physical condition and are safer than other classes of roads, although they are generally more congested. The states expect that increased traffic, the aging of the infrastructure, and funding constraints will affect their ability to maintain physical and safety conditions of the Interstate Systems and to alleviate congestion, but the costs to address the factors pressuring their Interstates were difficult to determine.

The System carries over 24 percent of all vehicle miles traveling in the nation, while making up just 2.5 percent of total lane miles. Funding for the Interstate Highway System has been a major part of total highway funding since 1954 when interstate highway construction began. From 1954 through 2001, federal funding for interstates total over $370 billion (2001 dollars)--46 percent of all apportionments administered by the Federal Highway Administration (FHWA) during this period. Congestion on interstate highways has increased over the last decade; the physical condition of interstate highways has generally improved, and the level of safety has remained steady. Some of the factors states expect to negatively affect the conditions of their interstate highways in the future include increases in passenger and freight traffic, aging infrastructure, and financial constraints. FHWA's estimates of future annual interstate highway investment requirements vary depending on the goal transportation officials have for performance of the interstate system. In 2000, GAO evaluated the model that FHWA uses to forecast interstate and other highways' pavement preservation and highway capacity requirements and found that this model can be useful as a general guide for assessing relative investment requirements over time. However, the model has some limitations; it does not fully account for uncertainties associated with its method, data, and assumptions.
