Bontddu railway bridge. 1929. Bontddu at Esgairgeiliog Ceinws was built in the 1870's by the Cambria Wynne quarry to connect their mill workshop to the Corris Railway across the river. It was also used by the villagers as a convenient, if sometimes dangerous route across to the main station and the main road. To prevent the bridge becoming a public right of way, there were two small gates on the two ends of the bridge, which were closed once a month and a shilling charged for crossing to keep it legally a private way. When the bridge started to fall into disrepair, a new lower and much safer footbtidge was built further down stream.
