Pair of culvert arches over River
Medlock and associated overflow


Pair of culvert arches. Probably 1765, by James Brindley, for
Duke of Bridgewater. Coursed squared sandstone. Two low
segmental spans at an angle, over the outflows from the River
Medlock culvert and the overflow culvert from the Giant's
Basin, that on the right lower and with a plain arch-band.
Part of hydraulic system by which the Bridgewater Canal
terminus basin exploited the course of the River Medlock,
which was diverted through a culvert running from east of
Deansgate at Knott Mill to this position, and the canal
overflow was returned to the river via a circular weir at
Potato Wharf known as the Giant's Basin. Simple stucture of
national historical importance. See also Giant's Basin, Potato
Wharf, and Floodgate, Deansgate.
