Cobham service area work moves forward on Surrey M25
Work to build a fourth motorway service area on the M25 has taken a step forward in Surrey.
The new Cobham service area near junction 10 at Wisley will fill a 65-mile gap between service stations on the motorway, the Highways Agency said.
Diversions are in place on the clockwise M25 so work to build slip roads can move into its next phase.
Lanes on both carriageways will be narrowed during the work, and a 50mph speed limit will be in place.
Highways Agency project manager Anne-Marie Palmer said the work was being funded by the motorway service developer with controls in place to ensure it met Highways Agency standards.
She said: "By keeping the maximum number of lanes open at all times and keeping construction traffic off the local road network, we are confident that we can keep traffic moving."
Work on the slip roads started in May and the diversions were put in place on Sunday.
The Highways Agency said all restrictions would be removed in time for the London 2012 Olympic and Paralympic Games and the service station was expected to open next year.
Currently, the M25 has service areas at South Mimms in Hertfordshire, Thurrock in Essex, and Clacket Lane on the Kent and Surrey border.
