There will be several long diversion routes in place from tonight (Friday, July 4) through the weekend as a full closure of the A3 will be in place several upgrades are made. National highways will close the A3 in both directions between M25 junction 10 and the Painshill roundabout from 9pm on Friday, July 4 until 6am on Monday July 7.
This will be so that teams can widen the carriageway, install a new gantry as well revamp other bits of technology and carrying out some road re-surfacing, as reported by sister site Surrey Live. The closure is part of the much wider Wisley Interchange project, which is slowly nearing completion after years of work.
