The Thunder Bay Expressway, originally known as the Lakehead Expressway is a high-capacity at-grade suburban limited-access road around the western side of Thunder Bay in the Canadian province of Ontario. The 15.3 km (9.5 mi) route travels in a generally north–south direction on the city's west side. It is signed as part of Highway 61 at its southern end, and as part of the concurrent route of Highway 11 and Highway 17. The expressway features several at-grade intersections between its southern terminus at Arthur Street West and the Harbour Expressway and its northeastern terminus at Hodder Avenue.
The Thunder Bay Expressway was built throughout the mid-to-late 1960s, and opened in stages between mid-1967 and late 1970. The old routes of Highway 11/17 and Highway 61 through Thunder Bay were redesignated as Highway 11B/17B and Highway 61B. Work is now ongoing to twin Highway 11/17 northeast to Nipigon.
