Highway Infrastructure Interstate Physical Conditions Have Improved, but Congestion and Other Pressures Continue

The Interstate Highway System (IHS) has become central to transportation in the U.S. With age & constant use, the system's roads & bridges have required significant levels of maintenance. Plus, 24% of all car & truck travel occurs on the IHS, contributing to growing levels of congestion. This report determines: (1) how the role of the IHS has changed over time; (2) the roles of the federal & state governments in managing & funding the IHS; (3) the financial resources that states & the federal government have devoted to the system; (4) how physical conditions, safety, & congestion of the IHS have changed & how they compare to other classes of roads; & (5) the factors that could affect future IHS conditions & the cost of addressing these factors.
