The majority of the route was located in the Regional Municipality of Peel; however, the section in Orangeville was in Dufferin County.

The majority of the former highway is rural in nature, passing through farmland on the highlands of the Niagara Escarpment, located a short distance south of the southern terminus of the route.

It begins at a junction with former Highway 24 (Charleston Sideroad) immediately north of Forks of the Credit Provincial Park, which straddles the escarpment northwest of Brampton.

[4][5] The road was first designated on February 10, 1937 as part of an extension of Highway 24 north from Guelph to Collingwood via Orangeville.
