Virginia State Route 37

State Route 37 (SR 37) is a primary state highway in the U.S. state of Virginia. Known as Winchester Bypass, it forms a western bypass of Winchester, connecting to Interstate 81 (I-81) at both ends. Although the road is a freeway, neither I-81 connection is freeway standard; the south end (exit 310) is a diamond interchange with two traffic signals, while, at the north end, drivers must use a short piece of U.S. Route 11 (US 11) to connect with I-81 at exit 317. In addition to local access, the highway connects to US 50 and US 522, two major highways that lead west and northwest into West Virginia and north to I-70 at Hancock, Maryland. An eastern bypass, known locally as "Route 37 East" has been proposed in statewide and local plans to complete the loop.
