National Highway System (NHS) planning maps
The National Highway System (NHS) is approximately 160,000 miles of roadway important to the nation's economy, defense, and mobility. The NHS includes the following subsystems of roadways.
- NHS Interstate: The Eisenhower Interstate System of highways retains its separate identity within the NHS.
- NHS Routes: These highways are secondary to the NHS Interstate, but still remain important to the national economy, defense and mobility.
- NHS Intermodal Connectors: These highways provide access between major intermodal facilities and the other subsystems making up the National Highway System.
The NHS encourages transportation planners to focus on a limited number of high-priority routes and to concentrate on improving them with federal-aid funds. At the same time, states can incorporate design and construction improvements that address their traffic needs safely and efficiently.
This site will be updated with new urban(ized) area and rural county NHS maps and planned routes reflecting the additions to the NHS made through the MAP-21 Surface Transportation Authorization Bill. In the mean time, see the PDFs of urban area NHS maps and planned routes available on the WisDOT FTP server, and corresponding PDFs of urban(ized) area or rural county Functional Classification maps – all Principal Arterials are now NHS.
