One person has died after a single-vehicle crash on the Anthony Henday early Thursday morning.

Emergency crews were called to the Henday just west of Manning Drive around 2 a.m. When they arrived they found a Toyota Corolla in the ditch. The lone occupant of the vehicle was outside of the vehicle.

The eastbound lanes of the Henday will be closed to traffic at Manning Drive for several hours while investigators are on scene.

Police believe drug impairment and vehicle maintenance may have been factors in the crash.

Anyone who witnessed the crash is asked to call the Edmonton police complaint line at 780-423-4567.
