Description
Pont Trefriw is a bridge built in the late 18th century or early 19th century, certainly after 1777 when plans for the new turnpike road were created. Survey plans from 1822 exist, although this does not necessarily indicate the construction date. The bridge features a wide, single-span design with a segmental arch. The rough-dressed voussoirs are set back slightly from a plain arch ring made of narrow stones. The parapets have rough-dressed coping stones and a plain band below, with battered piers on either side of the arch. A modern footway has been added on the west side, and the arch has been strengthened with modern strutting.
Local climate
Pont Trefriw sits in a wetter-than-average part of the UK, with an average of 1,100 mm of rain a year. This makes it wetter than 87% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 76% of listed buildings.
It experiences an average of 34 freeze-thaw cycles a year, fewer than 51% of listed buildings. Of these, 18 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.
Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
