Chicago River Bascule Bridge, State Street, Spanning Chicago River at State Street, Chicago, Cook County, IL
Summary
Significance: Providing for eight lanes of traffic, the State Street Bridge contains three lines of trusses, part of which serve as a railing for the roadway and sidewalks. The railing-truss height was first used in 1922 in the city's Madison Street Bridge and engineers later employed this feature in the Wabash Street Bridge (1930) and the State Street Bridge. (See Donald N. Becker, "Development of the Chicago Type Bascule Bridge," Transactions of the American Society of Civil Engineers, v. 109 [1944], 1021-22.)
