The Barton Swing Aqueduct is a moveable navigable aqueduct in Barton upon Irwell in Greater Manchester, England. It carries the Bridgewater Canal across the Manchester Ship Canal. The swinging action allows large vessels using the ship canal to pass underneath and smaller narrowboats to cross over the top. The aqueduct, the first and only swing aqueduct in the world, is a Grade II* listed building, considered a major feat of Victorian civil engineering.
