The A3 will be closed in Surrey tonight (Friday 11 April) - as works on the M25 motorway continue.

The major route will be shut from 9pm on Friday until at the latest 6am on Monday so that more works can be carried out on junction 10 of the London orbital route.

Healthlands are being restored and the Wisley Interchange upgraded to reduce congestion, improve safety and create more reliable journeys say National Highways.

The A3 will be shut between Junction 10 and Painshill Roundabout/A425 with the following alternate routes being suggested by highways bosses:
