A collision is causing huge problems on the roads this morning.

There has been a crash at Mill Hill Circus which has led to tailbacks from Edgware and Borehamwood.

The A1 is gridlocked between Rowley Lane, Borehamwood, and Mill Hill Circus while the A41 is solid from Broadfields Avenue to Apex Corner.

It means anyone travelling via Stirling Corner, Apex Corner, or Mill Hill Circus can expect severe delays.

Side roads have been affected too - Hendon Wood Lane is at a standstill from Barnet Gate to Totteridge Common while it's busy in both directions in Highwood Hill.

And the A411 Barnet Road is queuing from Furzehill Road in Borehamwood to the traffic lights in Elstree village, with all routes into Elstree struggling.
