Work continues this week on an upgrade to the central reservation barrier along the M25 between junctions 5 (Sevenoaks) and 6 (Godstone), ahead of a major improvement project scheduled to start in the spring.
Narrow lanes and a 50mph speed limit are in place, with a free recovery service operating 24 hours a day. There will be additional lane and slip road closures as required, which will be carried out overnight when traffic flow is lowest.
