M3 junction 9 improvements - Road Closures. 06/11

Bridge Demolitions

• 9pm Friday 6 November to 6am Monday 9 November 2026 (southern bridge demolition)
  • M3 junction 9 to 8 northbound and southbound diversions

Please ensure the signed diversion routes are followed, allow extra time and avoid unsuitable local roads.

Long-distance and freight traffic should use an alternative better suited route i.e. A37 to A30 to A34 or A3 to the M25, we ask these are incorporated into route planning.

***Important Information***

From Monday 14 September until late November 2026 Easton Lane westbound towards Tesco will be reduced to one lane. This to allow work to start on the embankment and the old southwest subway.

Don't Forget - M3 junction 9 northbound entry slip road will be closed from 9pm Friday 31 July 2026 until winter 2027 – this means there will be no access the M3 northbound from the roundabout.

The diversion routes are designed to suit all vehicle types.

You are advised not to use a Satnav when following any of the diversions because there is a risk it could direct you down an unsuitable road or back onto the network when it is closed.
