The Engine Arm Aqueduct near Smethwick, West Midlands, England, was built in 1825 by Thomas Telford to carry a water feeder, the Engine Arm, from Edgbaston Reservoir over the BCN New Main Line canal to the adjacent and parallel Old Main Line. It is a Scheduled Ancient Monument and is Grade II* listed.
It is a 52-foot (16 m) span structure consisting of a cast-iron trough supported by a single arch with five ribs, each consisting of four sections with bolted joints. The trough is supported on three of the ribs, with the adjacent towpaths being supported by cast-iron arcades of Gothic-styled arches and columns. All cast-iron features were manufactured at the Horseley Ironworks in nearby Tipton. The waterway in the aqueduct is 8 feet (2.4 m) wide with the towpaths either side being 4-foot-4-inch (1.32 m) in width each. The eastern towpath is paved in brick with raised strips for horses.
