Description

Furnace Bridge is a road bridge dating from an unknown period, built of rubble stone. It spans the Einion river with a single segmental arch. The arch is formed of stone voussoirs, slightly recessed and cemented together. A parapet is constructed from very large, long, squared stones.

Local climate

Furnace 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 95% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 92% of listed buildings.

It experiences an average of 35 freeze-thaw cycles a year, more than 57% 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.
