A cast iron trough aqueduct designed by Telford as part of his new Birmingham Canal works. It was built to take water from the old canal across the new to feed the nearby steam pumping station.
Telford's Birmingham Canal slices through the middle of Brindley's sinuous one of 1772, leaving the loops as branch links to established canalside businesses.
The high ground at Smethwick was excavated to form the Smethick Cutting, driving the new canal through at a lower level. The aqueduct carries the old Rotten Park feeder, at a level of 473ft 20ft higher than the new one.
The trough is 8ft wide, with a 4ft 4in wide towpath on either side. It is supported by a single arch, spanning 52ft, with five ribs, three of which support the trough. Each rib is made up for four sections, bolted together. Cast iron columns with decorative pediments and then-fashionable Gothic arches support the towpaths.
Ironwork: Horseley Iron Works, Tipton
