Description

New Bridge, also known as Gunnislake Bridge, is a bridge over the River Tamar, dating from around 1520, with some rebuilding to the parapet walls. It is constructed of granite ashlar, with the parapet walls made of rubble and topped with granite coping. The bridge measures a total length of 55 metres and features five triangular refuges on each side, six slightly pointed arches, imposts at the springing of the arches, and recessed arch rings with chamfered outer order. The ashlar rises to a string course and is built out in rubble above. The parapet walls are splayed back at each end.

Local climate

New Bridge sits in a wetter-than-average part of the UK, with an average of 1,000 mm of rain a year. This makes it wetter than 80% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 81% of listed buildings.

It experiences an average of 17 freeze-thaw cycles a year, fewer than 84% of listed buildings. Of these, 7 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.
