Union Chain Bridge

The Union Chain Bridge is a suspension bridge that spans the River Tweed between Horncliffe, Northumberland, England and Fishwick, Berwickshire, Scotland. When it opened in 1820 it was the longest wrought iron suspension bridge in the world with a span of 137m and the first vehicular bridge of its type in the United Kingdom

A Bridge of Innovation

The bridge was designed by Captain Samuel Brown, a naval officer and engineer. Brown had patented a new type of eye-bar chain that was stronger and lighter than the chains used in previous suspension bridges. It represents a remarkable feat of engineering for its time, featuring a suspension design supported by massive stone towers.

A Link Across Borders

As its name suggests, the Union Chain Bridge played a crucial role in connecting England and Scotland. The bridge was built in two years, at a cost of £7,700 and was opened on 26 July 1820 by the Duke of Northumberland. The bridge was a major engineering feat at the time, and it was widely acclaimed as a symbol of peace and unity between England and Scotland.

Architectural Significance

The Union Chain Bridge's design was ahead of its time, influencing the development of subsequent suspension bridges worldwide. Its stone towers, wrought iron chains, and wooden decking combine to create a structure that blends engineering practicality with architectural elegance.

Facts And Figures

The bridge spans 137m and is anchored to a free standing tower on the Scottish side and a tower melded to the rock face on the English side. The bridge is supported by two sets of chains, each of which consists of 180 eye-bars.

The Union Chain Bridge cost £7,700 and celebrated its grand opening on the 26th of July in 1820 and the ceremony was graced by the presence of esteemed figures, including the renowned Scottish civil engineer Robert Stevenson. Captain Brown, the bridge's designer, conducted a remarkable test in which he towed twelve carts with a curricle (two-wheeled chariot), all in front of a crowd consisting of approximately 700 spectators. The bridge operated with toll charges until the year 1885, and it's however the toll cottage on the English side was eventually demolished in 1955.

Longevity And Restoration

The Union Chain Bridge has been listed as a Grade I listed building since 1986. It is a popular tourist destination, and it is also used by local people as a crossing point over the River Tweed. In 2020, the bridge underwent a major restoration project that cost £10.5 million. The project included replacing the chains, repairing the towers and abutments (the bit which connects the deck of a bridge to the ground), and repainting the bridge. The restored bridge reopened to traffic in April 2023.

It's a fabulous construction and a lovely area for a wander with amazing views from the middle of the bridge.

If a car does traverse the bridge while you are on it, then it can get a little bouncy!
