A southbound lane of Anthony Henday Drive has reopened following a four-vehicle crash south of Yellowhead Trail NW.

It's unclear what caused the crash, but around 1 p.m. Wednesday, police asked drivers to avoid the route while emergency crews went to work.

Pictures posted to Twitter showed a large truck that left the road and a blue compact SUV with apparent damage to its rear end.

There is no word on injuries.
