DuSable Bridge

The DuSable Bridge is a double-deck, double-leaf trunnion bascule bridge that spans the main stem of the Chicago River, identifiable by the four ornate neoclassical bridgehouses that anchor its corners. Completed in nineteen twenty, it was a central feature of the nineteen zero nine Plan of Chicago, intended to link the city’s boulevard systems. Its design, heavily influenced by the Alexander the Third Bridge in Paris, features a sophisticated mechanism that rotates the heavy bridge leaves around fixed axles, allowing them to lift for boat traffic.
