Bridge Documentation

This location is truly unique, featuring three bridges: the Conwy Railway Bridge, the Conwy Suspension Bridge, and the Conwy Road Bridge, all located in the shadow of the beautiful Castle Conwy.

This riveted steel deck arch bridge is the youngest of three bridges at this location next to Castle Conwy. Although (in comparison to the castle and the other two bridges) this bridge is not very old having been built in 1958, it is of riveted construction and offers a nice comparison to the nearby older bridges, and because it is an arch bridge, it makes for a unique setting where three bridges next to each other crossing the same waterway each have a drastically different structure type.

An unusual feature of this bridge is that the spandrel wall is covered by a non-structural facade that hides the underlying structure. This facade appears to have been designed to harmonize with the visual appearance of the Conwy Railway Bridge, as it is a simple steel facing with vertical ribs, reminiscent of the appearance of the Railway Bridge's girder web.

Site Description

Single-arched steel road bridge of 1958 carrying the former A55 trunk road (nprn 403728) over the Afon Conwy; faced with stone on the north side to harmonise with nearby Conwy Castle (nprn 121). The bridge was constructed to supersede Telford's adjacent suspension bridge of 1826 (nprn 43083) and has itself been superseded by a road tunnel (nprn 409064) under the estuary opened in 1991.
