Highways chiefs are advising drivers to plan ahead as partial closures on the M3 are expected to cause delays.

Lanes one and two of the M3 northbound are currently closed between junctions 4 (Frimley) and 3 (Lightwater) to allow teams to repair a carriageway defect.

Work will involve removing and then relaying a large section of the northbound carriageway of the M3, with work expected to continue through the rush hour. Lanes three and four will remain open throughout.

Sam Day, South East traffic operations manager for National Highways, said: “This is safety-critical work and was identified following a routine inspection of the carriageway. We are gearing up to start the repair immediately, and advising drivers to expect delay and to avoid the area if possible.”
