Route description[edit]

Virginia and West Virginia[edit]

US 340 through Grottoes, Virginia.

US 340 begins at an intersection with US 11 just south of an interchange with I-64/I-81. It continues north, entering West Virginia and heading towards Charles Town and then Harpers Ferry, and then briefly re-enters Virginia before crossing the Potomac River into Maryland. The stretch of US 340 between Charles Town and Harpers Ferry is designated the William L. Wilson Freeway, although it does not share the same characteristics as a traditional freeway and includes traffic lights and at-grade interchanges. It is named for William Lyne Wilson, who served in the U.S. House of Representatives as a representative from West Virginia from 1883 to 1895, and as United States Postmaster General between 1895 and 1897. The northern entrance to Shenandoah National Park via Skyline Drive is found just south of Front Royal. The short segment in Virginia on the Potomac is called Jefferson Pike. This name carries over into Maryland on MD 180, the road US 340 bypassed. In West Virginia it served as the main business route through Charles Town, but was later placed on a bypass. The main section in Virginia is called Lord Fairfax Highway and is one of the main routes through Berryville, Virginia.


Continuing in Maryland, US 340 is called the Jefferson National Pike. North of Jefferson, US 340 merges with US 15, continuing north for about 5 miles (8.0 km) towards Frederick. After crossing I-70, US 340 ends at US 40 at a hybrid cloverleaf, and the road continues ahead as Jefferson Street, but US 15 continues, going onto expressway which is the same road as westbound US 40.
