The southbound off slip road of the A1(M) at Sawtry has been closed following a serious collision involving a lorry.
A Cambridgeshire police spokesman said the incident, which only involved the Huntingdonshire District Council bin lorry, happened at about 11am.
Three people have been hurt, and the police spokesman said it was thought two people, both passengers had suffered serious injuries. The driver escaped with minor injuries.
Councillor Jim White, Huntingdonshire District Council’s Executive Councillor for Operations said: “First and foremost, our thoughts are with the families of those involved, and I would ask everyone to respect the privacy of their families at this difficult time. We will of course provide updates as and when they are available.”
A spokesman for the East of England Ambulance Service said: “We were called at 10.51am to a lorry on the B1043.
“We sent the Magpas Air Ambulance, an ambulance officer and two ambulance crews.
“Three patients were treated in total. The most seriously injured, a man in his 50s, was airlifted to Addenbrooke’s Hospital in a serious condition.
“The other two patients suffered what are thought to be minor injuries. One was taken to Peterborough City Hospital, while the other was taken to Hinchingbrooke Hospital, both by land ambulance.”
The police spokesman said two people had been seriously injured in the crash.
A spokesman for Magpas said: “As the first emergency responders on scene, the Magpas enhanced medical team assessed the man (in his 40s) who had sustained multiple life-changing injuries. They provided him with pain relief before placing him into an induced coma (giving him A&E level care). With help from the Cambridgeshire Fire & Rescue Service they extricated the man before airlifting him to Addenbrooke’s Hospital. He was in a serious but stable condition upon arrival at hospital.”
The A1(M) remains open, but motorists are being advised of delays in the area. The road is expected to be opened at 4pm.
