THE A47 Fen Road was closed for almost four hours this morning after a crash involving a Royal Mail van and an ambulance near Guyhirn.

Huge traffic tailbacks were sparked by the incident, which happened just after 6am. The ambulance had its blue lights on and was carrying a patient.

Sources at the scene said the ambulance had been pulling out of Gull Road when the collision happened.

The road was closed in both directions as traffic queued between the A141 March Road junction in Guyhirn and the B1167 New Cut junction in Thorney Toll.

A diversion was put in place by Cambridgeshire Police and a police spokesman said the road was re-opened at around 10am.

A spokesman for the East of England Ambulance Service said: “We can confirm that an ambulance was involved in a collision just after 6am this morning on the A47 between Wisbech and March.

“The ambulance was conveying a patient to Peterborough City Hospital at the time. Another ambulance was dispatched immediately to convey the patient who remained stable throughout.

“Both members of the ambulance crew suffered minor injuries and were taken to the Queen Elizabeth Hospital in King’s Lynn and Peterborough City Hospital.

“The driver of the second vehicle was taken to Queen Elizabeth Hospital in Kings Lynn with leg injuries.”
