interstate highways

National numbered routes

Interstate highways are the network of major roads crossing state boundaries in the United States, built to federal standards with limited access, multiple lanes, and high speed limits.

The system, formally the Dwight D.

Eisenhower National System of Interstate and Defense Highways, connects major cities and facilitates long-distance travel: We took the interstate highways from Chicago to Denver.

Often shortened to interstates or simply the interstate.
