Pont King Morgan

Carmarthenshire County Council's new lightweight slender footbridge over the River Towy, UK is a new landmark structure linking the station with the town centre. The bridge has a single span over the river with the foundations wholly out of the river channel and backspans clear of flood levels, providing minimum impact on the river habitats. The river and floodplain are a Site of Special Scientific Interest. The County Council intends to improve the waterfront and historic quay at Carmarthen and it is hoped that the bridge will attract investment in the redevelopment. The bridge is a twin-masted, cable-stayed structure supporting a fabricated steel cycle/footway deck that is curved in elevation and S-shaped in plan. The deck widens at the pylons to provide viewing platforms. The deck has an effective skew over the river of 25 degrees from bank to bank. The steel pylons are 20m high. The inclusion of lateral ties between the deck and pylon foundations results in an increased lateral stiffness relative to that of a raked pylon design. Deck sections and pylons were fabricated by Rowecord Engineering Ltd. The sections were lifted into place using cranes. The bridge lighting uses Light Emitting Diodes.
