History of King's Highway 37B:
King's Highway 37B was a short-lived business route which served the small communities of Cannifton and Corbyville, located north of Belleville. The business route
was created in 1960, when Highway 37 was relocated onto a new alignment. The new Cannifton Bypass was completed and opened to traffic in October 1960. The old route
of Highway 37 which passed through Cannifton and neighbouring Corbyville was renumbered as Highway 37B. The route of Highway 37B was officially decommissioned in two
sections during 1961. Jurisdiction over the section of Highway 37B through Cannifton via Cannifton Road was transferred from the Department of Highways of Ontario
(DHO) to the Township of Thurlow on May 20, 1961. The balance of Highway 37B through Corbyville via River Road and Wiser Road was transferred on July 22, 1961. A
portion of Highway 37B through Corbyville (Wiser Road) was subsequently closed to through traffic by the township, so the route of Highway 37B is no longer drivable
from end to end. The former highway route followed Cannifton Road, River Road & Wiser Road.
