Overflow Channel And Culvert On North West Side Of Canal Bridge

The overflow channel and culvert, built around 1798 for the Rochdale Canal Company, is located on the north-west side of the canal bridge at Sowerby Bridge. Constructed from coursed squared stone, the overflow channel curves to the east, connecting with a beck and directing water from both the canal and the beck into a culvert that runs beneath the canal and into the River Calder. The channel features a stone ledge along the canal side, with walls and a base made of squared stone. It steps down to enter the segmental-arched culvert. The exit of the culvert on the riverside has a segmental arch supported by springers and large voussoirs, with substantial blocks positioned above a band. The overflow channel and part of the culvert are situated in the parish of Hebden Royd. For further historical context regarding canal construction, refer to Sowerby Long Bridge.
