Corridor L is part of the Appalachian Development Highway System in the U.S. state of West Virginia. It follows the path of U.S. Route 19 between Beckley and Sutton. By exiting onto Corridor L from Interstate 79 at milepost 57 a southbound traveler can eliminate 40 miles, and $2.25 in tolls, re-entering the interstate system at the West Virginia Turnpike (Interstate 64 and Interstate 77) at milepost 48.

Originally this corridor was built as a four-lane divided highway for only the half south of U.S. Route 60; however, the large amount of traffic (as part of the direct route from the cities of Toronto, Ontario, Buffalo, New York, and Pittsburgh, Pennsylvania to Florida) forced the state to rethink this plan and upgrade the northern half to four lanes as well.Fact|date=February 2007

High vehicle accident rates led to strict enforcement of traffic speed limits. The town of Summersville has been identified as a speed trap by the National Motorists Association.Fact|date=February 2007
