The eastbound lanes of the Yellowhead Highway were closed and traffic was being detoured onto side roads due to a fatal collision east of Edmonton Friday afternoon.
The crash happened on Highway 16 near Range Road 215, about 10 kilometres east of Sherwood Park. STARS air ambulance was also dispatched to the area.
Alberta Health Services said one man was airlifted by STARS to an Edmonton hospital in critical condition. A spokesperson for STARS later said the man is 82 years old and was taken to the Royal Alexandra Hospital in critical but stable condition.
Another adult was treated and taken to hospital in stable condition.
A third person died on scene, AHS said.
The RCMP said officers were called to scene of the multi-vehicle crash at about 4 p.m.
A Global News crew on scene saw traffic was flowing westbound, however eastbound was closed.
At 10:40 p.m., the RCMP said the scene had been cleared and traffic was no longer being disrupted.
