Conwy Railway Bridge

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. It is the last surviving example of this type of design by Stephenson after the original Britannia Bridge across the Menai Strait was destroyed in a fire in 1970 and replaced by a two-tier truss arch bridge design.

The Conway Railway Bridge was designed by railway engineer Robert Stephenson in collaboration with William Fairbairn and Eaton Hodgkinson. The original plan had been for suspension bridge complementing Thomas Telford's Conwy Suspension Bridge of 1826. After Stephenson's appointment as chief engineer, the design was changed because a suspension bridge was considered unsuitable for trains. Stephenson and his collaborators invented the wrought-iron box-girder structure to bridge the River Conwy in a single span.
