Interstate 68

Interstate 68 (abbreviated I-68) is an Interstate Highway in the United States. It runs from Morgantown, West Virginia, at Interstate 79 to Hancock, Maryland, at Interstate 70. During its construction, the route was designated U.S. Highway 48. Upon its completion as a 4-lane highway around 1989, US 48 was de-commissioned for the second time and was re-designated I-68. Interstate 68 is also known as Corridor E of the Appalachian Development Highway System. It is also known as the National Freeway in Maryland, named after the old National Road (US 40), which parallels I-68 east of exit 14 (Keysers Ridge). I-68 was fully completed in 1991.

The road is promoted by the Maryland State Highway Administration as an alternate to the Pennsylvania Turnpike, with signage on I-70 that informs motorists that I-68 is an alternate route to "Ohio and Points West".
