Union Chain Bridge

The Union Chain Bridge spans the River Tweed between Horncliffe in England and Fishwick in Scotland. It is a suspension bridge built with wrought iron chains, standing 449 feet above the water. Completed in 1820, it was the world’s longest wrought iron suspension bridge at the time. The bridge’s sandstone pier on the Scottish side and tower on the English side support its chains. Its approach roads curve sharply on the English bank due to steep river sides. The bridge is a Category A listed building in Scotland and a Grade I listed building in England. It holds the title of an International Historic Civil Engineering Landmark. Captain Samuel Brown designed the bridge after experimenting with iron chains for naval use. Robert Stevenson attended its opening ceremony in 1820, where Brown tested the bridge with a loaded curricle. The bridge once charged tolls until 1885, and its toll cottage was demolished in 1955. Visitors find a restored bridge that reopened in 2023 after a £10.5 million renovation. The bridge carries Sustrans Route 1 and the Pennine Cycleway, linking cycling routes across borders. Its chains appear on the Flag of Berwickshire, marking its place in local heritage. The surrounding landscape includes the river’s steep banks and the gentle approach road in Scotland. The bridge stands as a testament to early 19th-century engineering and remains in use today.
