Christmas Eve travellers are being warned of closures to a usually-busy stretch of motorway after a lorry struck a safety barrier.
The crash which took place early on Tuesday morning between junctions 7 and 6 of the M40, left the HGV overhanging a footpath below.
The southbound carriageway has been fully closed between junction 8a for Oxford and junction 6 for Lewknor while the vehicle is recovered, National Highways said.
Work to repair the damaged safety barrier will also have to be carried out.
During the closure, a diversion is in place via the A40.
Craig Sowden, operations manager for National Highways’ East region, said: “This collision has left an HGV balancing precariously over a footpath used by members of the public below.”
“We have looked at all possible options but the only way to manage this situation safely is to close the carriageway.”
