LaSalle Street Bridge


Northeast Pivot

When I think of a bascule bridge in Chicago, this is the bridge that I immediately think of. This bridge has been in several movie shoots.

The development of the Chicago trunion bascule bridge occurred during the first three decades of the twentieth century. Despite the controversy over patent infringement--Joseph E. Strauss charged the City of Chicago engineers with infringing on his patented Strauss-Trunion bascule bridge--the Chicago bascule received great acclaim within the civil engineering profession. The LaSalle Street Bridge was erected in the late 1920s after Chicago's city engineers had refined their design of the trunion bascule span.
