McCormick Bridgehouse & Chicago River Museum

The DuSable Bridge is a bascule bridge that carries Michigan Avenue across the main stem of the Chicago River in downtown Chicago, Illinois, United States. The bridge was proposed in the early 20th century as part of a plan to link Grant Park and Lincoln Park with a grand boulevard. Construction of the bridge started in 1918, it opened to traffic in 1920, and decorative work was completed in 1928. The bridge provides passage for vehicles and pedestrians on two levels. An example of a fixed trunnion bascule bridge, it may be raised to allow tall ships and boats to pass underneath. The bridge is included in the Michigan–Wacker Historic District and has been designated as a Chicago Landmark.

The location is significant in the early history of Chicago, connecting on the north near the 1780s homestead site of Jean Baptiste Point du Sable and on the south the early 19th century site of Fort Dearborn.
