Description

Pont Perfa is a double-span road bridge made of local limestone rubble. It features segmental arches with rough-dressed voussoirs that are recessed below the arch-rings made of narrow stones. The bridge has full-height cutwaters on both the down-river and up-river sides, which are shaped in a triangular profile. The carriageway has a gentle hump, and the rubble parapets are slightly splayed out at the up-river west and down-river east approaches, topped with limestone copings.

Pont Perfa receives an average of 940 mm of rain a year. This makes it wetter than 72% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 67% of listed buildings.

It experiences an average of 29 freeze-thaw cycles a year, fewer than 68% of listed buildings. Of these, 15 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.
