Spencer Bridge Engineering has won the Historic Bridge Project of the Year Award at the New Civil Engineer Bridges Awards 2024 for its work on the Union Chain Bridge crossing the border between England and Scotland.
Opened in 1820, Union Chain Bridge crosses the River Tweed. It’s the world’s oldest suspension bridge still carrying traffic and was the longest wrought iron suspension bridge in the world when it opened.
Joe DiMauro, Engineering Director said: “We’re incredibly proud to have been honoured with prestigious industry awards for our work on Union Chain Bridge.
“This recognition further reinforces Spencer Bridge Engineering’s reputation as an industry leader in specialist bridge works, including the delivery of projects on historic structures.
“Our expertise, experience and wide-ranging capabilities across the company mean we can be trusted to complete complex bridge works to exceptional standards. I’d like to thank the team for their tremendous work which made this project so successful and these awards possible.”
Designed and built by Royal Navy officer and bridges design pioneer, Captain Samuel Brown, the crossing was credited with being a catalyst for bridge innovation and influenced the design and construction of suspension bridges around the world.
Spencer Group was appointed by Northumberland County Council to dismantle the bridge and carry out a complete refurbishment and rebuild, ensuring the 200-year-old structure continues to provide safe passage for vehicles, pedestrians and cyclists for many years to come.
A key element of the project was to ensure all modifications were in keeping with the heritage and historical significance of the bridge and, where possible, structural elements, including the main suspension chain rods, links, pins and hanger caps, were refurbished rather than replaced.
The existing masonry towers were also refurbished using stone from the same quarry that was originally used. Working in partnership with local stonemasons and heritage bodies, the Spencer Bridge Engineering team conducted masonry trials to determine the exact stone facing and pointing techniques required to best match the existing structure.
