Summary
Significance: The development of the Chicago trunnion bascule bridge occurred during the first three decades of the twentieth century. Despite the controversy over patent infringement Joseph E.

The Franklin Street Bridge was completed at the same time the City of Chicago was settling the patent dispute with Strauss.
