Description

Bont Newydd is a bridge constructed from rubble. It features a single segmental arch made of voussoirs, supported by modern steel braces, with a cement-rendered soffit. There is a heavily-eroded inscription plaque on the upstream side. At the northern end, there is a rubble abutment on the downstream side. The roadway is ramped up at the northern end as it approaches the road junction, where the 1-meter high parapets have been partly rebuilt and include some concrete coping. On the downstream side, the parapet extends along the roadside for approximately 30 meters beyond the upstream side.

Bont Newydd sits in one of the wettest parts of the UK, with an average of 1,310 mm of rain a year. This makes it wetter than 95% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 91% of listed buildings.

It experiences an average of 45 freeze-thaw cycles a year, more than 86% of listed buildings. Of these, 26 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.
