Balfour Beatty, in partnership with National Highways, has reopened the M25 ahead of schedule, following the completion of the latest stage of improvement works for the Junction 10 improvement scheme.

The M25 between Junction 10 and 11 was closed at 9pm on Friday 12 July until around 11pm on Sunday 14 July, marking the third closure of the M25 since the beginning of this year.

During the closure, Balfour Beatty successfully installed 72 concrete beams which will form the second of the new Junction 10 gyratory bridges and lifted two new gantries into place – one being a 45 metre superspan gantry, spanning the entire width of the M25 carriageway.


Howard Williams, Balfour Beatty Project Director, said: "Another great achievement for Balfour Beatty and National Highways, as we reopen the M25 to the travelling public ahead of schedule following another complex weekend of works.

"I would like to extend my thanks to my colleagues and our supply chain partners who have worked tirelessly to make this latest closure a roaring success, and to the public who listened to the advice and followed the diversion routes."

Balfour Beatty will now turn its attention to the construction of the next modular bridge, which will take place offsite. The bridge will then be wheeled into place on a self-propelled modular transporter later this year.

The Junction 10 improvement scheme is due to complete in Summer 2025.
