King's Highway 37, commonly referred to as Highway 37, is a provincially maintained highway in the Canadian province of Ontario. Its northern terminus is at Highway 7 in Actinolite (part of Tweed Municipality), and its southern terminus was formerly at Highway 62 in Belleville; however, in 1998 the terminus was changed to Highway 401, also in Belleville. Prior to the re-routing, Highway 37 was 47 kilometres (29 mi) long; it is now 44 kilometres (27 mi) in length.
Highway 37 serves as a shortcut route between Ottawa and Toronto. It is well-maintained for its entire length, mostly traversing rural areas. The major settlement on the route between its termini is the village of Tweed.
Today, Highway 37 begins at an interchange with Highway 401, south of which it continues as Cannifton Road into downtown Belleville. North of Highway 401, the route curves to the northeast. At first, it travels parallel to the east side of the Moira River; however, the route soon crosses the river and thereafter travels parallel to the west side of it north to Tweed. Before entering that town, the route crosses the river again, and travels parallel to the east side of the river north to Actinolite, ending at Highway 7.
On January 6, 1932, the Department of Highways assumed the Belleville–Actinolite Road as King's Highway 37. The new highway travelled along existing Hastings County roads. Two bypasses were constructed through the 1930s. The first to avoid River Road, which crosses through the communities of Cannifton and Corbyville. The second was built to bypass Plainfield and thus provide a smoother alignment through that area. Since then, Highway 37 has remained more-or-less unaltered, with the exception of a truncation during the late 1990s. The section from Highway 62 north to Highway 401 was transferred to the City of Belleville.
