First planned daytime closure of the M25

M25 to close at junction 10 for full weekend

Drivers warned of first planned M25 closure

The M25 will be closed for a full weekend for the first time ever as a major project progresses to make journeys safer and reduce pollution.

This will be the first of five closures between now and late 2024. 

The motorway will shut in both directions between junctions 10 (A3 Wisley) and 11 (A320 Chertsey Interchange) from 9pm Friday 15 March to 6am Monday 18 March 2024 to demolish the Clearmount bridleway bridge and install a very large gantry.

The Junction 10 improvement scheme will see an increase in the number of lanes to make journeys safer and improve traffic flow. It will also make it easier and safer to enter and exit the M25, provide safer entry roads for Wisley, Pyrford, Old Byfleet and RHS Wisley. It will also reduce the pollution caused by traffic jams.

Without a full closure of the M25 at this junction, it would be impossible to safely demolish the overbridges and install the new gantry.
