This is one of the newest of Chicago’s bascule bridges, with a 1960 construction date. It continues to use the the combination deck-pony truss design that had been in use in Chicago since 1922. The bridge’s truss details are nearly identical in appearance to the earlier examples. That a truss bridge design was used with little changes over a period of 38 years is remarkable and is testimony to the effectiveness of the design. It’s 279 feet long and the roadway if 44 feet wide. This bridge was documented as a historic bridge in August 2006.
This is a shot of the Harrison Street bridge from the pedestrian walkway facing west while the sun was setting. It caught my eye and I thought it would make for a great photo.
