Bont-uchel

Large single-span road bridge constructed of squared, rough-dressed limestone blocks; approximately 20m long. Tall, wide segmental arch with rough-dressed voussoirs recessed below a projecting archring, and with large keystone to the up-river side. Flat carriageway with quarry-dressed parapets and copings, the former splayed slightly at the approaches, most noticeably at the S end; the copings are fixed with iron ties. Terminating square piers to the parapets on the S side and the down-river side of the N end; its opposite, to the S, has been disturbed by the subsequent construction of a building on that side; bench mark to the inner face of the southern up-river pier. Stepped-down from the latter is an associated section of parapetted rubble revetment wall which curves in an arc for approximately 8 m in 2 stages. Opposite this, on the southern down-river side, is a similar wall which follows the line of the road eastwards in an arc for approximately 50m; here it terminates some 3m short of a second, smaller road bridge (Bridge to E of Bont-uchel Chapel); slab copings.
