The A507 near Stotfold is blocked this morning after a three-vehicle crash, while a broken down car and heavy fog are causing long delays on the A1(M).

The A507 collision involved two cars and a van, with an ambulance currently on the scene.

The road – from Norton Road up to Junction 10 of the A1(M) for Stotfold and Baldock Services – is currently blocked both ways.

On the A1(M), a broken down vehicle blocking the southbound slip road for Junction 9 at Letchworth Gate from about 8.20am has caused delays, with the foggy conditions also adding to heavy traffic southbound between Junction 10 and Junction 7 for Stevenage.
