History of King's Highway 24T:
King's Highway 24T was a short highway which existed in the Waterford area during the 1960s. The route connected the relocated Highway 24 between Simcoe and Brantford to Main Street (Old Highway 24) in Waterford. The route was first established in 1966, when a section of the 9th Concession Road in the Township of Townsend was assumed by the Department of Highways of Ontario (DHO) as a new King's Highway. As originally assumed on August 26, 1966, Highway 24T began at Highway 24A (today's Highway 24) and headed easterly for 2.4 miles into Waterford. Highway 24T ended at the existing route of Highway 24, which at that time ran along Waterford's Main Street. It is not clear why the mysterious Highway 24T was established, although the route did serve as a new entrance highway to Waterford from the new route of Highway 24 which was under construction between Simcoe and Brantford. Although some may speculate that the route of Highway 24T was planned to be some type of interim or temporary route for Highway 24, plans and surveys indicate that the route of Highway 24T was actually in the planning stages for a considerable amount of time prior to the highway's assumption in 1966. This suggests that the route may have been intended initially to serve as a permanent entrance highway into Waterford from the relocated Highway 24, once the old route of Highway 24 through Downtown Waterford was decommissioned and transferred from the province to Norfolk County.
Although this route's legal name was King's Highway 24T according to DHO records, it is uncertain if the route was ever actually posted with Highway 24T route markers. This was the only route in Ontario to bear a "T" suffix. Highway 24T lasted only a couple of years before being decommissioned. The entire highway was transferred from the province to the Town of Waterford and the Township of Townsend, effective December 14, 1968. Former Highway 24T is now known as Norfolk County Road 9.
