The Allegheny Aqueduct near Gibraltar, is a historic stone aqueduct located in Robeson Township, Berks County, Pennsylvania. Built in 1824, it is about 260 feet long (79 m) and 70 feet wide (21 m). It was constructed as part of the Schuylkill Navigation Company canal system to carry canal boats across the Allegheny Creek. It is supported by a bridge structure with five stone arch spans. The aqueduct was in operation until around 1920, abandoned in 1931 and drained in 1967. Listed on the National Register of Historic Places in 1984, it was restored in 1989 and is now a Berks County Historical site. It is next to the site of the Beidler Mill, which operated using water from Allegheny Creek.
