Caerhowel Bridge (partly in Berriew community)

Caerhowel Bridge is a road bridge constructed from cast iron, featuring sandstone ashlar central and outer piers. It has two arches made up of five parallel cast-iron arches that consist of bolted segments, connected by horizontal and diagonal struts. The arches are designed with a cusped lattice pattern, and the large open spandrels include raking uprights. The road deck is supported by cast iron outer girders that have raised panel ornamentation, along with the inscriptions 'Thomas Penson County Surveyor 1858' and 'Brymbo Company Iron Founders 1858'. Above the deck, there are iron railings with dog-bars and trefoil heads set between full-height uprights.

The bridge features a rounded-ended central cutwater with a tooled chamfered band positioned below the sloping masonry from which the iron arches spring, also rounded at the front and topped with a rounded capstone. The piers are made of an unusual green sandstone ashlar, topped with a brown ashlar bullnosed cornice beneath an ashlar parapet pier that has a heavy tooled stepped cap, which is pyramid-topped. A plaque on the upstream side reads 'Thomas Penson County Surveyor 1858', while the downstream side displays 'Brymbo Company Iron Founders 1858'. The outer bridge piers are made of similar stone, and beyond these piers are abutments constructed from rock-faced stone, featuring a broad band beneath massive plain ashlar parapets topped with a thin iron rail.
