Highways Agency officers were called to make emergency repairs to a damaged barrier on the M25 on Saturday afternoon following a crash earlier in the day.
Two lanes of the clockwise carriageway were closed at around 12.20pm between junctions 8 (Reigate) and 9 (Leatherhead).
Repair crews were called in after a vehicle collided with a barrier protecting a bridge pier at around 6.30am. The incident was cleared and recovered by 9am but Highways Agency officers and an engineer were called in to repair the barrier and ensure the bridge had not been damaged.
Lanes one and two of the M25 were closed so the team could work in the area, causing delays for motorists.
