Signifying the outer boundary of the main business part of Runcorn old town, Delph bridge is actually a re-imagined bridge that was upgraded following Brindley’s construction of the canal in the late 1700’s. The remarkable thing about this bridge is that it originated in much the same way as the other canal bridges as a brick built structure, but here it was constructed directly onto a local sandstone ridge at either side of the cutting that surrounds the canal. However Runcorn expanded quite quickly after the arrival of the canal, and the route through Bridge Street demanded much more of the bridge, so the road had to be widened in 1846 by the Bridgewater trustees.
