摘要：	The National Highway System (NHS) is the centerpiece of the Federal Highway Administration's commitment to provide safe, modern, and efficient transportation system to serve the American people. As the cornerstone of tomorrow's highway network, NHS will function as the backbone of our nation's 21st century transportation system. Beyond the interstate segment, NHS consists mostly of existing two-lane roads. Approximately 98% of all roads in NHS already have been built. The 256,000 km of NHS include only 4% of the nation's roads, but they carry more than 40% of all highway traffic, 75% of heavy truck traffic, and 90% of tourist traffic. NHS serves 198 major ports, 207 major airports, 67 Amtrak stations, 190 rail/truck terminals, 82 intercity bus terminals, 307 public transit stations, 37 ferry terminals, 58 pipeline terminals, and 20 multipurpose passenger terminals. By providing these essential linkages to other modes, NHS creates a seamless transportation system for the rapid movement of people and products. About 90% of America's population lives within 8 km of an NHS road. Investing in NHS provides virtually every American with improved access to work and to market. In addition, NHS will confront the problems of traffic congestion by targeting current and projected bottlenecks. NHS consists of five parts: the almost 70,000-km Interstate Highway System, 21 congressionally designated high-priority corridors totaling 7,200 km, the non-interstate portion of the Strategic Highway Corridor Network (STRAHNET) identified by the Department of Defense, major STRAHNET connectors, and the remaining 148,000 km of important arterial highways that serve interstate and interregional travel.
