The southbound side of Reigate Hill will be closed for up to 14 weeks from next month.
The closure will allow repairs to the 240 metre retaining wall that runs along the A217 Reigate Hill, and replace the vehicle barrier that is supported by it. The twenty four seven closure will run from the M25 junction 8 roundabout stopping north of the petrol station and the Yew Tree pub.
The work will start on 7th September. A signed diversion will be in place. The road will remain open northbound.
