Occupational Health and Safety is investigating after a man working on construction of the southeast ring road was crushed between a crane and a truck and sent to hospital with life-threatening injuries.
Paramedics and safety inspectors say the man was helping to take apart a crane and lowering a boom onto a flatbed trailer. The boom shifted and pinned the worker between the crane and truck.
"It was a very large piece of crane machinery that trapped the patient," said Stuart Brid eaux, an EMS spokesman.
Paramedics rushed the man in serious, possibly life-threatening condition to the Foothills Medical Centre after a difficult extrication.
Emergency crews were called shortly before 2 p.m. to the site at Marquis of Lorne Trail and 52nd Street S.E.
"Occupational Health and Safety has been notified," said police duty inspector Paul Stacey.
Pam Sharpe, spokeswoman with Occupational Health and Safety, said the man is 26 years old and worked for Red Deer Piling. He suffered injuries to his legs.
"A stop-work order has been issued," she said.
Investigators will review how the accident happened.
