SN4019 : Bascule bridge, Carmarthen
taken 13 years ago, near to Carmarthen/Caerfyrddin, Carmarthenshire/Sir Gaerfyrddin, Wales

Bascule bridge, Carmarthen
The bridge carries twin-track railway lines over the River Towy at the western edge of Carmarthen junction, a triangular junction about 700 metres SW of Carmarthen railway station.
The bridge is a combination of a standard bridge with a bascule section on the right. Bascule is French for seesaw or balance. A bascule bridge is a moveable bridge with a counterweight to balance the span during its upward swing to give clearance for river traffic. A bascule bridge can be single span, as here, or double span, as is London's Tower Bridge (a combined bascule and suspension bridge).
