Cambridgeshire Police are appealing for witnesses following a serious collision involving a lorry overturning near St Neots this morning (November 3).

At about 10.30am, the HGV collided with the roundabout linking the A428 with Cambridge Road (B1428) and then overturned, spilling its contents of grain across the road.

Officers and paramedics attended the scene. The driver of the HGV, a man in his 50s, was taken to hospital with serious injuries, where he remains in critical condition.

The A428 has now been closed in both directions between B1043 and A1198 near St Neots, and National Highways expects the closure to be in place for several hours.

The police are diverting traffic via local routes at this time.

Collision investigation work is also underway and ongoing on the road.
