Information About

Michigan Avenue Bridge




The Michigan Avenue Bridge is a Bascule Bridge that carries Michigan Avenue across the Chicago River in downtown Chicago, Illinois .

The bridge was built in 1920 as two parallel bridges that operate independently of one another. It is one of the first examples of a fixed trunnion bascule bridge, which later became widely known as a "Chicago style bascule". When it was completed it was the main link between the north side and downtown. It is a double-deck double-leaf bascule with a main span length of 220 feet.
