Description

Tongland Bridge was built between 1804 and 1808 and is often attributed to Thomas Telford, although there is evidence that Alexander Naysmith contributed to the design. The bridge features a main segmental central arch with an approximate span of 110 feet, flanked by round full-height buttress towers, each with three narrow pointed arches on either side.

The structure is made of bull-faced granite masonry, with the arches showcasing boldly rusticated voussoirs. It has a corbelled embattled parapet, and the buttresses serve as pedestrian refuges, with splayed abutments and parapets.

Local climate

Tongland Bridge sits in one of the wettest parts of the UK, with an average of 1,290 mm of rain a year. This makes it wetter than 94% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 95% of listed buildings.

It experiences an average of 30 freeze-thaw cycles a year, fewer than 64% of listed buildings. Of these, 13 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.2°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.
