Ontario provincial highway
Secondary Highway 529, commonly referred to as Highway 529, is a provincially maintained secondary highway in the Canadian province of Ontario. Located within Parry Sound District, the highway follows a 25.7-kilometre (16.0 mi) route, from its southern terminus at Highway 69 near Pointe au Baril to its northern terminus at the Highway 69 crossing of the Magnetawan River near Byng Inlet. Two spur routes, Highway 529A and Highway 645, branch off the highway to serve the communities of Bayfield Inlet and Byng Inlet, respectively. The route was established along the present alignment of Highway 529A in 1956. It was relocated in 1961 along the former routing of Highway 69 when a bypass opened through the area, with the former alignment being renumbered as Highway 529A.
