History of King's Highway 28A:
King's Highway 28A was created in 1954, when the new high-level bridge on Highway 28 at Youngs Point was completed and opened to traffic. The old alignment of
Highway 28 through Youngs Point was briefly known as Highway 28A. The highway was very short-lived, and was formally decommissioned as a King's Highway in 1956.
Jurisdiction over Highway 28A was transferred from the province to the Townships of Douro and Dummer, effective December 6, 1956. It is not known if the Highway 28A
route number was actually posted along this short highway. If it was a posted route number, it would be Ontario's shortest signed King's Highway.
