Allegheny Aqueduct, Suspension bridge in Pittsburgh, United States
The Allegheny Aqueduct extends across the Allegheny River with seven spans of 162 feet each, carrying water through a channel 15 feet wide and 8.5 feet deep.
Engineer John Augustus Roebling completed this pioneering wire cable suspension bridge in 1845 at a cost of $62,000, replacing an earlier wooden covered structure from 1829.
The aqueduct represented an advancement in American engineering, integrating wooden truss members with innovative wire rope technology as part of the Pennsylvania Canal system.
The structure connected 11th Street in the Triangle to Voeghtly Street on the Northside, forming a vital transportation link within Pittsburgh's infrastructure network.
This project marked Roebling's first suspension bridge design, establishing construction methods he later applied to other major structures across the United States.
