Description

Pont Newydd is a single arched road bridge constructed from coursed rubble stone, featuring cut stone voussoirs that form the arch. The bridge has blank roundels in the spandrels on either side. There are lower flood channels on each side, also with matching voussoirs. The bridge heads are supported by raised piers, and there is a coped parapet wall on a projecting course. The underside of the arch was reinforced in the later 20th century with a concrete plinth and low revetment, which supports arched steel beams. Additionally, the sides of the bridge have later 20th-century reinforcing rods with circular steel ties.

Pont Newydd sits in one of the wettest parts of the UK, with an average of 1,250 mm of rain a year. This makes it wetter than 93% 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 16 freeze-thaw cycles a year, fewer than 84% of listed buildings. Of these, 6 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.
