M40 traffic caused by car crash near Bucks Oxon border

The collision happened on the southbound carriageway between Junction 6 for Lewknor and Junction 5 for Watlington in the late morning on Saturday, August 29.

The emergency services attended the scene and closed the road,

National Highways said lanes two and three of the three-lane motorway were shut as a result while crews dealt with the incident, leading to delays of around 40 minutes.

Congestion was worsened by separate lane closures between Junctions 4 and 5 in both directions following damage to the central reservation from an earlier incident.

Traffic built up on approaches to the crash, with nearby areas including Stokenchurch and Lewknor also affected.

Images from traffic cameras showed long queues of vehicles and emergency workers at the scene throughout the afternoon.

AA Travel also reported that one lane was closed on the northbound carriageway between Handy Cross and Stokenchurch due to emergency repairs.

National Highways later confirmed that all southbound lanes between Junctions 6 and 5 had reopened and that the lane closures linked to the earlier incident were also being removed.

Despite the reopening, delays of around 40 minutes remained on the approach as traffic slowly returned to normal.
