Harrison Street Bridge (Chicago)

The Harrison Street Bridge is a fixed-trunnion bascule bridge in Chicago, Illinois, crossing the South Branch Chicago River.

History

While the current iteration opened in 1960, two previous iterations took the place of the current bridge. The first bridge opened in 1877 as a hand-operated swing bridge after nearby property owners advocated for the crossing. The second bridge, a Scherzer rolling lift bascule bridge, was built from 1901 to 1905; the former swing bridge was dismantled in the process. The "Scherzer" bridge was eventually closed in December 1959 in favor of the current fixed-trunnion bridge, which opened on August 23, 1960.

The western bridge approach, situated above railroad tracks leading to Chicago Union Station, is currently under reconstruction.
