History of King's Highway 17B (North Bay):
North Bay's Highway 17B Business Route was created in 1958, when the former route of Highway 17 through Downtown North Bay was given a new route number. For several years following the completion of the North Bay Bypass in 1953, both the old route of Highway 17 through the city (via Main Street and Fisher Street) and the North Bay Bypass were posted with the Highway 17 route number. This led to some confusion amongst motorists who found that Highway 17 split into two routes on the approaches to North Bay. During 1958, the Department of Highways of Ontario (DHO) decided that the old route of Highway 17 through Downtown North Bay via Main Street and Fisher Street would be renumbered as Highway 17B. The route of Highway 17B ran concurrently with Highway 11B along a portion of Main Street lying between Fisher Street and Cassels Street. On November 20, 1958, an Order-in-Council was signed which designated the non-assumed portion of Highway 17B through the City of North Bay as a Municipal Connecting Link. The DHO retained ownership of Highway 17B through neighbouring Commanda Township, situated immediately west of North Bay. In the mid-1970s, Highway 17B was rerouted along a system of one-way streets through Downtown North Bay. Between Fisher Street and Cassels Street, Highway 17B followed Oak Street southbound and McIntyre Street northbound. The revised route of Highway 17B through the new one-way street system was designated as a Municipal Connecting Link by an Order-in-Council dated August 21, 1974. The route of Highway 17B remained more or less the same from the mid-1970s up until the late 1990s. North Bay's Highway 17B Business Route was 6.3 km in length up until 1998. The Municipal Connecting Link designation for North Bay's Highway 17B was formally repealed by a Minister's Order dated November 6, 1998. However, the westernmost 1 km section of Highway 17B in adjacent Commanda Township was retained in the King's Highway system and is still maintained by the province to this day.
