Interstate 68 - National Freeway

Home » Guides » Maryland » Interstate 68 - National Freeway

Interstate 68 follows the National Freeway from the state of West Virginia east to Interstate 70 at Hancock. The highway travels across the Appalachian Mountains across the Maryland panhandle through the city of Cumberland. The 82-mile route overlaps with U.S. 40 for all but the westernmost 14 miles.

Constructed in stages between 1963 and 1991 as part of Appalachian Regional Development Corridor E, Interstate 68 was originally intended to remain U.S. 48 until it was determined that the National Freeway was a good, toll-free alternate route to the Pennsylvania Turnpike (Interstates 70 and 76). The Interstate 68 designation, which was originally considered for the current U.S. 50 (hidden Interstate 595) corridor between the Capital Beltway (Interstate 95-495) and Annapolis, was transferred to U.S. 48 in 1991.
