Description
Pont Gam is a high single-arched bridge made of coursed sandstone. The bridge features a segmental arch with a tooled arch ring. On the southeast side, there is a rounded and stepped cutwater, located where the Neath and Tennant Canals meet. To the southwest, a ramped approach is set at an angle with the parapet, which is corbelled out over the abutment on the east side.
On the north side, the parapets curve out at acute angles and are also corbelled out over the abutment on the west side. The parapets descend to water level and retain much of their original flat stone coping, although some sections have been partly renewed with concrete, particularly on the east side.
Local climate
Pont Gam sits in one of the wettest parts of the UK, with an average of 1,380 mm of rain a year. This makes it wetter than 97% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 96% of listed buildings.
It experiences an average of 28 freeze-thaw cycles a year, fewer than 69% of listed buildings. Of these, 12 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.
