A crash has closed a dual carriageway this afternoon (July 31).

Emergency services have been at the scene of a collision on the A1081 London Colney bypass.

The crash, which happened at around lunchtime, was serious enough to temporarily close the dual carriageway in both directions.

Hertfordshire Fire & Rescue Service says it was called at 12.37pm to a crash involving two vehicles.

It happened on the southbound carriageway in the direction of the Bell Roundabout/junction 22 for the M25.

Fire engines from St Albans and ambulances attended and the A1081 was closed both ways to allow the emergency services to work safely.

An air ambulance is also believed to have attended. 

It is unknown how serious any injuries sustained were; however by 3pm only police remained on scene along with a recovery truck.

A Peugeot was just off the road and had damage to the rear of its vehicle, while a Fiat 500 was on the recovery vehicle.

The incident scene is adjacent to the entrance to the industrial estate off the A1081, where the Sainsbury's distribution yard is based, but on the other side of the carriageway.

The A1081 remains closed towards the Bell roundabout by police but it has reopened in the direction of the London Colney roundabout and the A414.

When a full closure was in place, traffic was badly affected in London Colney High Street and at the Bell roundabout, including drivers leaving the M25.

Shoppers leaving Colney Fields retail park also faced delays. 

The London Colney roundabout remains slower than usual but it looks like the dual carriageway will be fully reopened soon.
