Pont-y-blew

Pont-y-blew is a bridge made of ashlar sandstone, featuring a single segmental arch that spans off square abutments. The arch consists of one ring of regular voussoirs and lacks a keystone, with the structure set back below a flush regulating course. The spandrils rise to a slightly arched square string band, which supports orthostatic parapets that were formerly cramped at the top. The bridge has been reinforced and widened by adding a concrete slab beneath the string course, increasing the overall width of the bridge to 4.05 meters, which accommodates a carriageway of 3.6 meters.
