Beyond the Interstate Highway System: It May Be Time to Rethink the State-Federal Relationship

The country's Interstate Highway System will be 50 years old in June 2006. This commentary examine the changes that have occurred since the Interstate system was reaching completion 25 years ago. Traffic on the Interstates has more than doubled since 1980, from about 296 billion vehicle miles traveled in 1980 to more than 702 billion in 2003, while capacity of the system has remained virtually unchanged. Maintaining bridges and pavements of the 42,700 mile system is consuming a major share of available highway resources. The commentary discusses the directive of the National Commission on the Future of the Interstate Highway System to "develop a conceptual plan with alternative approaches for the future of the Interstate System" for 15-, 30-, and 50-year horizons. A wide range of issues as projected future demands include: the necessity to accommodate rising freight movements, the need metropolitan vs. interregional expansion of road capacity, and, perhaps most important, the changing federal role.
