A crash on the A1(M) this afternoon near Hatfield has caused congestion along the stretch.
Police were called to the southbound carriageway in the Hatfield Tunnel to reports that a silver Toyota Land Cruiser with a connected trailer had collided with the barrier at around 3.20pm.
The crash caused the vehicle to face the wrong way on the carriageway, resulting in two lanes being closed by police and Highways England officers.
A police spokeswoman said no one was injured but officers are still at the scene helping with traffic management and recovery of the trailer.
All lanes have since reopened but motorists are being warned of knock-on delays.
