Dated to 1816, this is among the older surviving cast iron arch bridges in
the United Kingdom. It is also noted, especially among the older examples, as a
multi-span example. Also of note, the length and design of the spans varies. The
bridge is a very attractive structure and one of the more well-known cast iron
arch bridges in the United Kingdom.
Although it has received some minor alterations in the form of added
steel to strengthen some of the cast iron arch ribs, the original cast iron for
the most part remains in place on this bridge, including interior and fascia
arch ribs, and bracing between arch ribs.

Road bridge over river Wye. Dated 1816, by John
Raistrick. Cast iron carried on five ribs of five segmental arches
graded from the centre and carried on four massive stone breakwaters,
approximately elliptical, and with larger plinths at low water level;
abutment on Chepstow side, and abutment to right-angled return in road
on Tutshill side. Continuous plain railed balustrade with evenly spaced

singularly graceful design with roadway rising to centre.
History Built 1816. John Rennie (best known for
his designs for Waterloo, Southwark and London Bridges) originally
provided two designs, one for strengthening an existing bridge, one for
rebuilding. The eventual design built however, adapted from Rennie, was
by John Urpeth Raistrick of Haseldine and Raistrick of Bridgnorth. Water
colour drawings of the designs and the report are held by Chepstow
Museum. Raistrick specialised as an engine engineer and advised Brunel.
Central span strengthened in 1889 by placing steel box-girder ribs under
the 3 cast iron ribs. Foundations strengthened 1914 by driving concrete
piles into the river bed. Further strengthened in C20. A plaque
recording high tide in 1880s is low down on the right bridge abutment.
