Ontario Highway 81

King's Highway 81, also known as Highway 81, was a provincially maintained highway in the Canadian province of Ontario. The winding north–south route connected Highway 2 in Delaware with Highway 21 in Grand Bend, passing through Mount Brydges, Strathroy and Parkhill en route.

Route description

Highway 81 once served as a connecting route between Highway 2 and Highway 7 before its role was largely supplanted by the completion of Highway 402, which generally parallels the southern half of the route. Beginning at former Highway 2 in Delaware, what is now known as Middlesex County Road 81 travels west through Campbellvale, Mount Brydges and Caradoc, curving slightly to the northwest. The route travels through a large swath of farmland between Caradoc and Strathroy, the latter from which it exits to the north. After crossing Highway 402 at Exit 65, the highway encounters former Highway 22 at Wrightmans Corners.

From Wrightmans Corners, the highway takes a veering route north and west towards Parkhill, bisecting the communities of Crathie and Bornish. Immediately southeast of Parkhill, Highway 81 and Highway 7 shared a brief concurrency, though neither are provincial highways today.
