Description

Pont-rug is a bridge constructed from roughly coursed rubblestone, featuring a coped parapet, piers, and abutments. It has a wide single-span segmental arch over the river, made with ashlar voussoirs and an arch-ring. The bridge extends as a causeway to the south-east, which includes an additional semi-circular arch over the former railway.

Pont-rug sits in one of the wettest parts of the UK, with an average of 1,380 mm of rain a year. This makes it wetter than 97% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 98% of listed buildings.

It experiences an average of 25 freeze-thaw cycles a year, fewer than 73% of listed buildings. Of these, 12 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.
