The Harbour Expressway is a four-lane highway with signalized intersections running the Intercity business district of Thunder Bay, Ontario, Canada.

Thunder Bay City Council looked at renaming the road since it doesn not fit the general definition of an expressway but has decided that it would be unnecessary.

The highway bisects the Intercity area, which is primarily composed of big box retail stores and office parks.

[3] The completed expressway was opened by Transportation Minister James Snow at a ribbon-cutting ceremony on August 27, 1979.

The entire route is located in Thunder Bay District.
