The Conwy Railway Bridge carries the North Wales coast railway line across the River Conwy between Llandudno Junction and the town of Conwy. The wrought iron tubular bridge, which is now Grade I listed, was built in the 19th century by Robert Stephenson. It is the last surviving example of this type of design by Stephenson after the Britannia Bridge across the Menai Strait was destroyed in a fire in the 1970s.
The bridge was constructed to carry the Chester and Holyhead Railway across the River Conwy. Robert Stephenson, in collaboration with William Fairbairn and Eaton Hodgkinson, provided the engineering plans. Before their involvement it was intended to be a suspension bridge, complementing the 1826 Conwy Suspension Bridge by Thomas Telford. However, after Stephenson's appointment as chief engineer, the design changed because a suspension bridge was considered not robust enough to carry trains. Stephenson and his collaborators invented wrought-iron box-girder construction in order to bridge the River Conwy in a single span.
