Virginia State Route 37

SR 37 southbound west of Winchester

Route 37 begins at an intersection with Hillandale Road (SR 847), a local frontage road along the east side of I-81, and Tasker Road (SR 642), which leads southeast to US 522 near Armel. It immediately crosses I-81 at exit 310, a diamond interchange with two traffic signals on SR 37, and then becomes a freeway, soon junctioning US 11 (Valley Pike) with a partial cloverleaf. The next interchange is a diamond at Cedar Creek Grade (SR 622), and SR 37 reaches its approximate midpoint at US 50 (Northwestern Pike), another diamond. A trumpet interchange completed in 2001 connects to the Winchester Medical Center, and the final diamond is with US 522 (Frederick Pike) at the northwestern corner. SR 37 ends at a partial Y interchange with US 11 (Martinsburg Pike), at which SR 37 traffic can only access US 11 north and only traffic from US 11 south can access SR 37, although a northbound exit to Cives Lane was added in about 2000 to allow SR 37 traffic to access US 11 south. About 1/2 mile (1 km) of US 11 is a divided highway, connecting SR 37 with I-81 at exit 317.[7]

Route 37 was defined as the proposed Winchester By-Pass by 1963,[8] and was included in the statewide Arterial Network when it was created in 1964.[9] When I-81 opened past Winchester in November 1965,[10] it included an interchange south of Winchester, taking traffic between I-81 and US 11 along a short connecting road.[11] The north half of the bypass, from US 50 west of Winchester north and east to US 11 north of the city, opened in the late 1960s,[11] and the semicircle was completed in the late 1970s, with the linking of Route 37 to the existing I-81/US 11 connection. A new bridge carrying southbound SR 37 over I-81 was built, but otherwise the diamond interchange was not modified.[12] The only change to the major bypass since it was constructed has been a new trumpet interchange serving the Winchester Medical Center; construction began in September 2000[13] and was completed in November 2001.[14] A single ramp from SR 37 north to Cives Lane, allowing traffic at the north end of the bypass to access US 11 south, was built in about 2000.[15]

The entire route is in Frederick County.
