Bridge and Causeway to Former Quarry at Chwarel-y-Fedw.

The Bridge and Causeway to the Former Quarry at Chwarel-y-Fedw is a Grade II listed structure. It features a slate-rubble causeway that is approximately 230 meters long, extending in an arc from the road, across the river Lledr, and ending at the railway line. The longest section, about 180 meters, leads to the river and includes a 9-span clapper section made of large slatestone slabs, with cutwaters on the upstream, convex side. On the opposite side of the river, there is a similar 10-span clapper section that rises slightly in the middle and is connected to the first section by a modern timber bridge. The causeway stands approximately 1.2 meters high and is 1.8 meters wide, constructed of dry-built, random rubble. It features a metalled footpath and, in part, a 20th-century wire fence.
