Force refers itself to watchdog after bridge fall

Sgt Joe Calvert, from the force's road policing unit, said: "As a result of this incident, a man is currently in hospital in a life-threatening condition.

"Our thoughts are with him and his loved ones at this time."

The drivers of the lorry and Vauxhall Adam car both stopped at the scene.

"Nobody has been arrested and they are being treated as witnesses to the collision," the spokesperson said.

The motorway was closed in both directions following the incident but has since reopened.

Police have appealed for any witnesses or anyone with dashcam footage to contact them.
