History of King's Highway 75 (#2):
The King's Highway 75 designation was almost resurrected for a new highway route that was being planned through the Regional Municipality of Niagara and the County of Haldimand north of Dunnville in the early 1970s. The Department of Highways of Ontario designated a land plan on January 14, 1971, which specified the creation of a new provincial highway link between Highway 3 at Canborough and Highway 20 at Bismarck. Although the new highway was legally designated, it was never actually built. Had it been constructed, the new highway would have been 10.7 miles in length and would have been known as Highway 75. It is not clear why the highway was never built. However, it is quite possible that highway planners eventually acknowledged that the existing county road network in the area would suffice in carrying the traffic volumes that were expected to use the new highway facility. The first Highway 75 existed in Elgin County southwest of St. Thomas between 1936 and 1957.
