Expanded National Highway System (NHS)

The District Expanded NHS Maps below show the original NHS as well as the routes that were added to the NHS due to MAP-21 (Expanded NHS) for each District including Local routes. In the right column is a wall size statewide map of the new expanded NHS and 2 excel files, one for the state routes and one for the Local routes, that identify the locations by county route section including jurisdiction.
