New Gaunless Active Travel Bridge Reconnects Visitors with Railway Heritage
A historic section of the Stockton and Darlington Railway has been brought back to life by Beaver Bridges following the installation of a new steel bridge as part of a 12-mile walking and cycling route in County Durham.
The trail follows the original railway line, which opened in 1825 and marked a major milestone in transport history with the introduction of the world’s first steam-powered passenger railway service.
The new Active Travel bridge manufactured at our Forge 44 facility, recreates the historic Gaunless Bridge, built between 1823 and 1824. The original structure was the first lenticular iron railway bridge and is regarded as a pioneering example of iron bridge construction for the modern railway.
Designed to reflect the original bridge’s “quality and ingenuity”, the new structure combines historical inspiration with modern engineering. Its contemporary design incorporates reinforced concrete pile foundations, weathering steel parapets and a deck made from recycled glass-reinforced plastic.
Architectural weathering steel railings line both sides of the sloping approaches to improve safety for walkers and cyclists, while a reinforced slope provide secure access between the bridge and the embankment.
The bridge will complete the S&DR Active Travel Route, developed to mark the railway’s bicentenary. Following the original line from Witton Park to Darlington with the aim to give visitors the opportunity to explore the railway’s historic landscape while encouraging Walking & Cycling.
Cllr Tim McGuinness, Durham County Council’s Cabinet said: “We are delighted to be restoring a key part of County Durham’s history with the installation of the new Gaunless Bridge. Creating a new Gaunless Bridge has been a large and challenging project and this marks an exciting milestone for everyone involved.
Once complete, people will be able to explore the original line and reconnect with our county’s incredible railway heritage.”
