Michigan Interchange

The Gordie Howe International Bridge project requires significant construction activity, including the demolition and removal of existing infrastructure, reconstruction of select roadways and bridges, and construction of new project infrastructure.

One of the project components is the Michigan Interchange connecting to Interstate-75. Approximately three kilometres or 1.8 miles of I-75 between Springwells Street and Clark Street will require modifications to accommodate the ramps connecting to the US Port of Entry (POE). The ramps are designed to minimize the impact interstate/international traffic may have on local roads located in the vicinity of the US POE.

Michigan Interchange activities also include associated local road improvements. Over a dozen roadway and pedestrian bridges crossing I-75 and ranging in length from 30 to 518 metres or 100 to 1,700 feet will need to be constructed.
