A10 Closed for Three Weekends to Install New Bridge Near Waterbeach

A section of the A10 will be closed for three weekends in September to facilitate the installation of a new bridge near Waterbeach, aimed at enhancing travel for cyclists and pedestrians to Cambridge. The closures will take place from the Cambridge Research Park roundabout to the Denny End Road junction in Waterbeach, starting on September 6 and concluding on September 21, 2025.

The A10 will be closed each weekend from 20:00 on Friday until 04:00 on Monday, allowing for uninterrupted work on the bridge. This bridge, designed by the master developer Urban&Civic, will create a direct, predominantly off-road route for active travel to Cambridge, connecting the new town to the recently upgraded Mere Way.

To further minimize disruption, an additional closure will occur simultaneously on the A10 from the Denny End Road junction to the Car Dyke Road junction. This coordinated effort will help reduce traffic congestion in surrounding areas, particularly for large vehicles and heavy goods vehicles.

The project is critical for improving local infrastructure. Paul Mumford, Project Director for Urban&Civic, emphasized the importance of the new bridge, stating, “This significant piece of infrastructure for Waterbeach will provide residents and the wider community with a direct, predominantly off-road, active travel route to Cambridge.” He noted that the bridge is part of a broader initiative that includes future transport projects like the Park & Ride and busway planned by the Greater Cambridge Partnership.

The weekend closures will allow for 24-hour working, with the bridge lift scheduled for the first weekend. The subsequent weekends will be used for finalizing the installation, which includes tarmacking and path lighting.

Karl Lomas, Project Manager at GRAHAM, acknowledged the inconveniences these closures may cause, stating, “We understand that these road closures will impact local people travelling in the area, and our team will be working 24/7 during these periods to complete the complex lifting installation of the 90-metre, 150-tonne steel bridge as efficiently and safely as possible.”

The completed bridge is expected to open in early 2026, marking a significant step towards enhancing active travel options for the community. The Cambridgeshire County Council will oversee the essential works to ensure minimal disruption during the installation process.

Residents and road users are encouraged to plan their journeys accordingly and explore alternative routes during the closures.
