In Virginia, U.S. Route 11 (parallel to Interstate 81) was built along the GIW route. From the Cumberland Gap and Appalachian mountains at the Tennessee border, the fork called the Chesapeake Branch led northeast, passing west of what is now Bristol, then through the sites of present-day Abingdon, Glade Spring, Marion, Rural Retreat, Fort Chiswell (another possible westward gap route), Draper, Ingle's or Pepper's ferry, Salem, Roanoke and Amsterdam, then up the Shenandoah Valley through Buchanan, Lexington, Staunton, Harrisonburg, Winchester. From Winchester, most GIW routes briefly enter West Virginia, then continue northward into Maryland and Pennsylvania.
