National Highways report junctions 4, Frimley, and 3, Lightwater, on the M3 Northbound will be partially closed.
This is due to a carriageway defect.
Lanes one and two are currently closed, but lanes three and four will remain open while infrastructure repairs are taking place.
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.’
Work will involve removing and then relaying a large section of the northbound carriageway of the M3.
This is expected to last through rush hour.
National Highways advises commuters to plan their journeys in advance.
Traffic monitoring system ROMANSE reports there will be ‘heavy delays’ of approximately 50 minutes.
