After crossing the Potomac River, U.S. 340 briefly enters Virginia before entering West Virginia near Harpers Ferry and Charles Town, then re-entering Virginia on the way to its terminus with U.S. Highway 11. This stretch of U.S. 340 between Harpers Ferry and Charles Town 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. 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 U.S. 340 bypassed. In West Virginia it served as the main business route through Charles Town, but was later placed on a bypass. When it re-enters Virginia, the highway is called Lord Fairfax Highway and is one of the main routes through Berryville, Virginia.
