Barmouth Bridge

Barmouth Bridge is a single-track viaduct that carries the railway across the River Mawddach estuary on the coast of Cardigan Bay, Wales. It sits between Morfa Mawddach and Barmouth and caters for rail, foot and cycle traffic.

The bridge opened in 1867, and originally included a drawbridge section at its north end for tall ships to pass, though this was later replaced by the current swing bridge section. In 1980, woodworm threatened the safety of the bridge, which needed major repairs to avoid closure.

The bridge is a Grade II* listed structure, and has one of the longest timber viaducts still in regular use.
