Description

The West Bridge, also known as St Thomas Bridge or the Footbridge Riverside, is a late medieval packhorse bridge located over a river in Launceston. It is constructed from slatestone rubble with large slate dressings and features wrought-iron railings. The bridge has five spans, with two cut-waters and four-centred arches on the upstream side and one arch on the downstream side. Late 19th-century railings and a central cast-iron lamp are also present. Currently, only the arch heads are visible, as the piers are submerged due to the river's silting.

Local climate

The West Bridge sits in a wetter-than-average part of the UK, with an average of 1,030 mm of rain a year. This makes it wetter than 83% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 84% of listed buildings.

It experiences an average of 18 freeze-thaw cycles a year, fewer than 82% of listed buildings. Of these, 8 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.
