Description

The Carmarthenshire Dock tramroad bridge is a well-constructed single-arched stone bridge, believed to date from 1805. The long abutments are straight on the northern side but curve slightly outward at the south-eastern wing, and they are battered on the upstream side. The bridge features a shallow segmental arch, which is now made of red brick, while the bridge itself is constructed from carefully dressed sandstone. On the north elevation, the arch is inset to accommodate weir planks for damming the river, likely to assist with the scouring of the dock. The large copings are level with the bridge deck, which is characteristic of early 19th-century tramroad bridges, being flat and lacking parapets. Unusual iron stanchions bolted to the copings support modern railings.

Local climate

Carmarthenshire Dock tramroad bridge sits in one of the wettest parts of the UK, with an average of 1,430 mm of rain a year. This makes it wetter than 98% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 99% of listed buildings.

It experiences an average of 10 freeze-thaw cycles a year, fewer than 91% of listed buildings. Of these, 3 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.
