Cadw's description

In an elevated position, set well back from the N side of the A4212 leading W of Trawsfynydd.

Late C19 viaduct, formed part of the Trawsfynydd to Bala section of the Conwy valley line. The Bala to Ffestiniog section of the line was opened on November 1st 1882, passenger services withdrawn on 2nd January 1960 and freight services withdrawn on 27th January of the following year. The Great Western Railway built the line from Bala in a bid to capture a share of the lucrative Blaenau slate traffic, unfortunately it failed to do so. It did, however, get a great share of traffic in terms of troop trains to Trawsfynydd to serve the Army ranges in the mountains to the S-E of the village.

Late C19 viaduct of local stone; comprising 10 round arches.

Included as a C19 railway viaduct which forms a prominent local landmark.
