Motorists around Gloucester are bracing for significant disruption as National Highways prepares to undertake vital repairs on the A40 Over Bridge. The maintenance work, scheduled over eight months from June 2026 to March 2027, will necessitate overnight closures and lengthy diversions—forcing drivers onto a 40-mile alternative route.
The A40 Over Bridge serves as a key artery linking Gloucester, Cheltenham, and Ross-on-Wye. It carries approximately 5,000 vehicles per hour during peak times, underscoring its importance for commuters, local businesses, and freight transport. The planned repairs address critical structural issues including concrete restoration, waterproofing, drainage enhancement, and other improvements to extend the bridge’s lifespan and reduce the risk of emergency closures.
The works will begin with overnight closures starting June 29, between Over roundabout and Highnam roundabout, with traffic diverted through the A417 and A449 routes. Subsequently, the overtaking lane will close in both directions to facilitate central barrier repairs and the installation of a contraflow system later in the summer. Notably, the slip road from A417 Over Causeway to A40 Westbound will remain closed for the duration.

At a recent Gloucestershire County Council meeting, concerns were raised over the impact on emergency response times, particularly for fire services west of the River Severn. Cllr Paul Hodgkinson reassured attendees that emergency services would maintain access throughout the closures, emphasizing the council’s commitment to addressing any arising issues promptly.
County officials are also advocating for a baseline road condition survey on diverted routes, aiming to hold National Highways accountable for any required repairs due to increased traffic. Gloucestershire County Council is actively coordinating with utility companies to minimize additional roadworks in the affected areas and closely managing permit applications to limit congestion.
Terry Robinson, engineering lead for National Highways South West, highlighted the necessity of the £7 million investment: “Many major roads were built over 60 years ago and need renewal to remain safe and functional. This complex scheme is vital for the long-term resilience of the A40 and will inevitably cause some delays, so we advise drivers to plan ahead and seek alternative routes where possible.”
Motorists should expect a mix of lane closures, contraflows, reduced speed limits (30 mph), and clearly signposted diversions throughout the project timeline. While these measures will ensure the route remains open most of the time, preparation and flexibility will be essential to navigating the disruption.
Gloucestershire residents and commuters are urged to check traffic updates regularly, plan journeys carefully, and consider off-peak travel to help alleviate congestion and maintain safety during this critical infrastructure upgrade.
