Description

This pair of culvert arches, likely built in 1765 by James Brindley for the Duke of Bridgewater, is located over the River Medlock and an associated overflow channel. Constructed from coursed squared sandstone, the arches feature two low segmental spans positioned at an angle. The right arch is lower and has a plain arch-band. These arches are part of the hydraulic system that allowed the Bridgewater Canal terminus basin to utilize the River Medlock's course, which was diverted through a culvert from east of Deansgate at Knott Mill to this site. The canal's overflow was returned to the river via a circular weir at Potato Wharf, known as the Giant's Basin. This simple structure holds national historical significance.
