History

The present bridge is the third bridge at the site and remains the oldest steel bridge in the United States. In 1818, a wooden bridge was built across the Monongahela by Louis Wernwag at a cost of $102,000. This bridge was destroyed in Pittsburgh's Great Fire of 1845. The second bridge on the site was a wire rope suspension bridge

The bridge's short clearance from the river as well as its deteriorated condition convinced PennDOT officials to demolish the bridge and to replace it with a modern bridge. Lobbying by Pittsburgh History and Landmarks Foundation on the merits of preserving the bridge were considered by officials. In 1994-1995 the bridge was rehabilitated with a new deck, a colorful paint scheme, and architectural lighting. The abandoned rail lines became an extra traffic lane and there was an addition of a light-controlled bus lane which is activated during peak traffic hours. The bridge also has the distinction of being the most heavily walked pedestrian bridge, mostly commuters that park at Station Square
