Wabash Avenue Bridge, basculating bridge in Chicago
The Wabash Avenue Bridge is a double-leaf bascule bridge that spans the main stem of the Chicago River in downtown Chicago.
Built in 1930, this iconic bridge replaced a swing bridge that had been at the same location since 1899.
The bridge has been featured in numerous films and television shows, symbolizing Chicago's architectural heritage.
It serves as a major thoroughfare for vehicles and pedestrians connecting the northern and southern parts of the Loop.
The bridge's leaves are so perfectly balanced that it can be opened with just a 75 horsepower motor.
Location: Illinois
Official opening: 1930
