Loughor bridge

Loughor bridge is a steel and concrete road structure that crosses the Loughor Estuary, linking Gorseinon on the eastern side with Loughor on the western side. The A484 crossing accommodates both vehicle traffic and pedestrian movement through dedicated walkways on each side.

The present structure was completed in 1988, replacing a wooden swing bridge built in 1833 and a concrete bridge from 1923. This succession of crossings reflects the growing traffic needs and engineering improvements spanning more than 150 years.

The bridge stands as a symbol of regional development, marking the boundary between Carmarthenshire and Swansea counties with distinct language preferences on road signs.

Pedestrians and drivers can use the bridge safely with dedicated pathways on each side away from traffic. Weather conditions over the water can change quickly, so it helps to plan crossings during calmer times and wear appropriate clothing for exposure.

During low tide, traces of earlier crossings become visible in the riverbed where old support pillars from previous bridge structures still protrude from the water. These submerged remains are a tangible reminder of how many centuries of movement have happened at this spot.
