Major Roadworks on M25 Roundabout at Swanley Interchange to Last 5 Months, Drivers Advised to Plan Ahead

Drivers in the Swanley area should prepare for major roadworks on the M25 roundabout at Junction 3, which will last for the next five months.

Starting on June 17, National Highways will be carrying out strengthening works on the west bridge of the Swanley Interchange, which runs over the A20. This follows similar work that took place last year on the roundabout’s east bridge.

The purpose of these repairs is to ensure the safety of the bridges and ensure they can handle the predicted increase in traffic in the future. The work is expected to continue until early November, and drivers are advised to plan for extra travel time and follow the diversion signs that will be in place.

Similar to last year’s project, there will be lane closures and a temporary steel safety barrier will be installed on the west bridge to separate workers from moving traffic. The repairs will begin in the right-hand lane, with work shifting to the left-hand lane in late August and continuing through September and October.

In order to minimize disruption to drivers, the western section of the roundabout, between the A20 westbound entry and eastbound exit slip roads, will be closed overnight on June 17 and 18 between 10pm and 5am. A diversion will be in place via the A20 westbound to the Crittalls Corner roundabout and back. This same route will be used for approximately 20 future overnight closures.

The Swanley Interchange is a crucial connection for the M25 and M20, providing access to the Kent ports, London, and the south east. It is also a gateway to popular local attractions such as Brands Hatch and the Kent Downs. Drivers are advised to plan their journeys accordingly and stay informed of any updates or changes to the roadworks.
