The National Highway System
�
“The purpose of the National Highway System (NHS) is to provide an
interconnected system of principal arterial routes that serve major population centers,
international border crossings, ports, airports, public transportation facilities and
other intermodal transportation facilities and other major travel destinations; meet
national defense requirements; and serve interstate and interregional travel.”
(Title 23, United States Code, Section 103)
�
All highways deemed to be of significant importance to the economic and security
interests of our Nation are included in the NHS. In Maryland, 1,360 highway miles
make up the NHS. There are 486 miles of Interstate and 874 miles of non-Interstate
highways on the Maryland NHS.
