An iconic bridge known locally as ‘Gunny Hill’ due to infamously having anti-aircraft guns placed above it during the war. It carries the Bridgewater Canal over Red Brow Lane, and because the road slopes, one side of the bridge is higher above the road than the other. The bridge has height restriction signs on the parapets to warn road traffic about the height. Confusingly each sign is a different height reflecting that each side of the bridge has a different height above the road. The two heights on the bridge are a modern sign stating 7 feet 9 inches, whereas an older style sign indicates 8 feet 3 inches. No one seems to have considered what would happen if a vehicle of a height between the two were to go under the bridge from the side with the most headroom. This clearly must have caused issues in the years following the construction of Murdishaw on the west side of the bridge, and paired with the narrow Norton railway crossing along the road, subsequently the underbridge no longer permits public vehicle traffic.
