High Quality Content by WIKIPEDIA articles! State Route 37 (SR 37) is a primary state highway in the U.S. state of Virginia. It forms a western bypass of Winchester, connecting to Interstate 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 to connect with I-81 at exit 317. In addition to local access, the highway connects to U.S. Route 50 and U.S. Route 522, two major highways that lead west and northwest into West Virginia and north to Interstate 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.
