Barmouth Bridge Location within Wales

Barmouth Bridge (Welsh: Pont Abermaw), also known as Barmouth Viaduct, is a single-track largely wooden railway viaduct that carries the Cambrian Coast Railway across the River Mawddach estuary on the coast of Cardigan Bay, Wales. It sits between Morfa Mawddach and Barmouth in Gwynedd 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. Tolls were collected for foot and cycle traffic until 2013. The bridge is a Grade II* listed structure, and has one of the longest timber viaducts still in regular use in Britain.

The bridge crosses the estuary of the River Mawddach from Morfa Mawddach near Arthog northwards to the edge of Barmouth. The line is operated by Arriva Trains Wales, with connecting services south to Aberystwyth and east to Welshpool and Shrewsbury. The section containing the bridge is on the Cambrian Coast railway between Machynlleth and Pwllheli. The bridge is a Grade II* listed structure about 699 metres (764 yd) long and contains 113 wooded trestles supported by a series of cast iron piers. It is one of the longest timber viaducts still standing in Britain.
