Wales' only Bascule Bridge, across the Tywi at Carmarthen.

A Bascule bridge is a moveable bridge with a counterweight that continuously balances a span, or "leaf", throughout its upward swing to provide clearance for boat traffic. Once a fairly common feature, with the demise of high-masted ships the need for bascule bridges diminished and now there are only twenty remaining in the UK, the most famous being Tower Bridge in London.

Wales' only Bascule Bridge, across the Tywi at Carmarthen.

In Wales there is now only one remaining - it carries the Paddington to Fishguard railway across the river Tywi at Carmarthen. Also known as The White Bridge, it was built in 1903 and came down for the last time in 1956.

Although it can clearly be seen from the road bridge that carries the A40 across the Tywi, to allow you to get a closer look there is now a cycle way come pathway that will take you right up to it and from here you can really appreciate its grandeur as well as get an idea of the engineering that made it all work.
