The A1(M) has reopened northbound after a multi-vehicle crash led to a “significant” oil spill.

Traffic was stopped on the motorway between junction 6 at Welwyn and junction 7 at Stevenage, in Hertfordshire around 9.15pm.

Drivers were warned to expect delays, while a live traffic camera showed stationary traffic queuing on the motorway.

National Highways said on X, formerly Twitter, around 9.40pm: “All emergency services are on scene.

“Thanks for your patience if you're caught within the queue.”

National Highways urged those stuck in the queue of traffic: “Please don't take it upon yourself to turn around & drive the wrong direction back up the J6 entry slip road.

“Police will shortly be attending the slip road to address vehicles doing so.”

Meanwhile Hertfordshire Police urged people to avoid the area.

In a statement on Monday morning, National Highways said: “At 8.52pm on Sunday, 24 March 2024, police attended a road traffic collision at junction 6 northbound of the A1(M) that resulted in oil spillage and damage to a barrier.

“The road was subsequently closed, with National Highways also in attendance, and reopened at midnight.”
