Description

Top Lock Bridge, built in 1816, is a canal bridge on the Leeds - Liverpool Canal. It is constructed of stone and features a stilted segmental-headed arch that spans the lower approach to Top Lock, which is part of a series of seven locks. The bridge has buttress piers, bands, and parapets with flat coping. Its walls are battered and curve inwards towards the center. The bridge is structurally integral with the entrance to the lock, with the northern coping forming one side of the footbridge over the lock.

Local climate

Top Lock Bridge sits in one of the wettest parts of the UK, with an average of 1,200 mm of rain a year. This makes it wetter than 91% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 87% of listed buildings.

It experiences an average of 38 freeze-thaw cycles a year, more than 73% of listed buildings. Of these, 20 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.
