Description

Glan Rhyd Railway Viaduct is a triple-arched structure built in 1829. It is constructed from coursed rubble and features segmental arches with tooled voussoirs and prominent keys. The piers are designed with pointed cutwaters that are moulded and stepped. Above the arches, there is a tooled string course and a parapet topped with large stone copings, although part of the eastern side has been replaced with concrete. On the western side, the parapet includes an engraved tablet that reads: 'THIS BRIDGE WAS ERECTED IN THE YEAR 1829 BY MORGAN THOMAS, LALESTON, MASON', with the letters highlighted in black paint.

Local climate

Glan Rhyd Railway Viaduct sits in one of the wettest parts of the UK, with an average of 1,190 mm of rain a year. This makes it wetter than 91% 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 18 freeze-thaw cycles a year, fewer than 83% 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.

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.
