A 210-year-old wrought iron bridge has been fully closed to the public following the detection of fresh cracks.
The Old Wye Bridge in Chepstow had already seen cars prohibited from using it since October 2025, when structural engineers initially raised concerns about fracturing.
A follow-up inspection carried out in March 2026 revealed additional fractures, leading to the bridge being shut completely from March 27 onwards, with pedestrians and cyclists now also unable to cross.
A Monmouthshire County Council official said ensuring public safety continues to be the primary focus for all local authorities.
The council recognises that this closure creates considerable challenges for local residents and plans to work together with Chepstow Town Council and Tidenham Parish Council to explore every possible avenue for minimising the impact.
The approach includes collaborating closely with specialist engineers to ensure decisions are based on evidence, subject to review, and focused on maintaining this essential river crossing for the long term.
Technical experts have concluded that the bridge is under significant strain, with a real risk of part of the deck supported by Pier 2 collapsing.
Initial analysis suggests the latest damage stems from stress caused by freezing temperatures, compounded by deterioration from years of traffic loading.
Monmouthshire County Council, Gloucestershire County Council, and The Forest of Dean District Council are now joining forces with specialist engineering consultants to conduct thorough assessments.
Plans for repair are also under consideration to determine what construction work would be required to enable the bridge to reopen safely.
A Gloucestershire County Council spokesperson said the authority understands the vital part the Old Wye Bridge plays in how residents go about their daily lives, and appreciates how frustrating and disruptive this closure has been.
The crossing was shut to safeguard the public, and the council supports that decision.
A Forest of Dean District Council spokesperson stated public safety must remain the top priority, and the council has confidence that both highway authorities will be able to resolve these issues swiftly for the benefit of the communities they share.
