Planned M25 closures and central reservation work on the A3

We’ve finished putting in narrow lanes and a reduced speed limit on the A3 around the Wisley interchange and will be starting some work in the central reservation. We need to remove the lighting columns and metal barriers within our safe working area so we have enough space to carry out our improvements.

Overnight closures on the M25 start next week – Tuesday 7 February

We also need to install narrow lanes and put in a reduced speed limit on the M25 underneath the junction and will need to close the motorway overnight in both directions at different times between junction 9 (Leatherhead) and 11 (Chertsey).
