There were rush-hour delays of 40 minutes on a major motorway heading to London after a crash involving several vehicles - but the accident has now been cleared.
National Highways says that the inside lane of the M3 was shut between Junction 3 for Bracknell and Junction 2 for the M25 because of a “multi-vehicle collision”.
It said traffic officers are on the scene, and estimated that disruption could continue until about 10am. The AA traffic monitoring website said it was first reported at 6.35am.
National Highways has now confirmed that the motorway is running as usual again.
