State Route 9 (SR 9) is a primary state highway in the U.S. state of Virginia. Known as Charles Town Pike, the state highway runs 13.08 miles (21.05 km) from the West Virginia state line near Mechanicsville, where the highway continues west as West Virginia Route 9 (WV 9), east to SR 7 and SR 7 Business in Paeonian Springs. SR 9 is the main east–west highway of northwestern Loudoun County, connecting Leesburg with Hillsboro and the West Virginia cities of Charles Town and Martinsburg. As a result, the state highway and its West Virginia continuation are a major, overburdened commuter route between the Eastern Panhandle of West Virginia and Washington, D.C..
SR 9 begins at the West Virginia state line at Keyes Gap, a wind gap on top of Blue Ridge Mountain. The highway continues west as WV 9 to Charles Town. SR 9 heads southeast as a two-lane road, passing to the west of Purcell Knob as the highway descends Blue Ridge Mountain to the village of Mechanicsville in a valley known as Between the Hills. At the eastern edge of the narrow north–south valley, the state highway parallels the North Fork of Catoctin Creek through Hillsboro Gap, a water gap in Short Hill Mountain, into the town of Hillsboro. SR 9 continues east through the much wider Catoctin Valley, crossing the North Fork and intersecting SR 287 in the hamlet of Wheatland. The state highway veers southeast and crosses the South Fork of Catoctin Creek before reaching the community of Paeonian Springs. SR 9 curves south to its southern terminus at Clarke's Gap, a low point in Catoctin Mountain. The state highway expands to a four-lane divided highway and meets SR 7 (Harry Byrd Highway) at a diamond interchange. SR 9 is paralleled through the interchange by the Washington and Old Dominion Trail. At the southern end of the interchange, the highway continues southward as SR 7 Business (Colonial Highway), which immediately turns west toward Hamilton.
Route 9 has been the subject of considerable debate. West Virginia has constructed a four-lane expressway by-pass of the former Route 9 - a winding two-lane rural road - to U.S. Route 340 in Charles Town. The expressway ends at Route 9 at the Virginia state line , raising concerns in Loudoun County about increasing traffic along the road's narrow, winding stretch through the town of Hillsboro. A proposed bypass of Hillsboro was considered as part of the County's long range transportation plan, debated publicly, and rejected by the County Board of Supervisors in June 2010. Instead, the town of Hillsboro is studying traffic calming measures  in hopes of encouraging West Virginia traffic to detour through Clarke County via U.S. Route 340 and Virginia State Route 7.
The entire route is in Loudoun County.
