Properly called the M25 Holmesdale Tunnel Refurbishment and Junction 25 Improvements. The works will provide a third lane eastbound through junction 25 (previous works provided the third lane westbound), and widen the adjacent Holmesdale Tunnel to dual four lane. It will also provide essential refurbishment work on the electrical and mechanical equipment within the tunnel.
This scheme was completed in and we're no longer accepting updates or changes to this page.
The eastbound lane was opened this month, ahead of schedule, and the speed limit through the roadworks was increased accordingly. The westbound exit and eastbound entry are both still closed.
Works were finally completed in early September.
