National Highway System


The National Highway System (NHS) was established by National Highway System Designation Act of 1995 and approved by Congress, and is the network of nationally significant highways that are important to the nationís economy, defense and mobility. With the Moving Ahead for Progress in the 21st Century Act (MAP-21) of 2012, the scope and extent of the NHS was modified. The latest update consists of a network of strategic highways within the United States. The NHS includes all the Interstate highways, all principal arterial highways and a small portion of mileage on the other functional systems that are most critical to national defense, mobility and commerce that connects with other modes of transportation (major airports, ports, rail or truck terminals, rail stations and pipeline terminals). The National Highway System is the largest highway system in the world.New Jersey Map Sussex County Passaic County Bergen County Morris County Warren County Hunterdon County Somerset County Middlesex County Hudson County Essex County Union County Monmouth County Mercer Ocean County Burlington County Camden County Gloucester County Atlantic County Salem County Cumberland County Cape May County

The NHS was developed by the Department of Transportation (DOT) in cooperation with the states, local officials, and metropolitan planning organizations (MPOs).  There are approximately 2,970 centerline miles currently of NHS miles throughout the state of New Jersey.
