History of King's Highway 12B (Port McNicoll):
This short business route began at the original Highway 12 Junction (at Talbot Street and Triple Bay Road), and entered town along First Street. The
highway ended at the intersection of First Avenue. The road leading into Port McNicoll was assumed as a King's Highway by the province on April 13, 1938,
but it is not known if it was actually signed as Highway 12B at that time. It is quite possible that the route was initially an unmarked King's Highway,
and the Highway 12B designation was applied later. The highway was 1.9 km long. The highway was decommissioned in 1977, when a new Highway 12 Bypass was
built that completely bypassed Port McNicoll. If anyone has more information on the Port McNicoll Business Route, please email me. Four other Highway 12B
Business Routes have existed over the years in Orillia, Coldwater, Gamebridge and Victoria Harbour.
