Motorists in Gloucestershire are bracing for significant disruption as essential repairs to the A40 Over Bridge near Gloucester will trigger a lengthy 40-mile diversion. This major maintenance project, managed by National Highways, is set to run from June 2026 through March 2027, with work focused on the bridge that carries the dual carriageway over the River Severn, a key link connecting Gloucester, Cheltenham, and Ross-on-Wye.
The upcoming road closures have sparked concern among local communities and health officials, who warn the detours could double travel times for emergency services and hospital patients. At peak times, the A40 experiences traffic volumes of around 5,000 vehicles per hour, underscoring the importance of this route for commuters and freight alike.
Initial overnight closures are scheduled to begin on June 29, from 8 PM to 6 AM, between the Over roundabout and Highnam roundabout. During this period, motorists will be diverted along a circuitous route via the A417 and A449, resulting in extended journey times. Subsequently, an overtaking lane closure will commence on June 30 to facilitate central barrier repairs and the installation of a contraflow system later in the summer. The slip road from the A417 Over Causeway to the A40 westbound will remain closed throughout the project.

Councillors and emergency service representatives have voiced concerns regarding response times and road conditions on diversion routes. In response, Gloucestershire County Council is conducting baseline surveys on alternative roads and working with National Highways to ensure rapid resolution of any issues. Fire service officials have been assured that emergency access will be maintained despite the restrictions.
Terry Robinson, engineering lead for National Highways in the South West, emphasized the vital nature of the repairs. “The A40 at Over was built in the 1970s," he noted. “This £7 million investment will extend the bridge’s lifespan, enhance safety, and reduce the risk of unforeseen closures caused by emergency repairs.”
The scope of work includes concrete repairs, new waterproofing, improved drainage, and various upgrades designed to increase the route’s resilience. To prioritize safety, a 30 mph speed limit will be enforced throughout the affected areas, alongside lane closures and contraflows. Overnight closures will be closely managed with clear signage to minimize inconvenience.
Gloucestershire County Council is proactively coordinating with utility companies to prevent additional roadworks that could exacerbate congestion during the repair period. The council’s Streetworks Team is also scrutinizing permit applications to limit overlapping disruptions.
In light of the anticipated delays, drivers are advised to plan journeys carefully and use alternative routes where feasible, especially during peak hours. The combined efforts of National Highways and local authorities aim to balance necessary infrastructure improvements with minimizing impact on residents, businesses, and commuters.
