One person was taken to hospital after a car veered off the QE2 near Blackfalds during the morning commute and rolled into a slough.

It happened shortly before 8, just north of the Highway 597 overpass, with northbound traffic reduced to one lane for over an hour.

Constable Mitch Gardipee with the Ponoka Traffic Section says the car rolled multiple times.

No word on the extent of injuries or what contributed to the crash.
