UPDATE 4:27 p.m. from Innisfail RCMP:

Innisfail RCMP are redirecting northbound traffic onto Highway 2A from Highway 2 due to a two vehicle collision. Normal traffic flow is not expected to resume for several hours.

Motorists can rejoin Highway 2 by heading east on Highway 42 at Penhold, Alta, or simply continue north to Red Deer, Alta.

Southbound traffic is unaffected.

UPDATE 3:05 p.m.:

Traffic is being re-routed from QE2 at Hwy 590 into Innisfail for northbound drivers so that they can use Highway 2A between Innisfail and Red Deer. 

-

We are hearing reports of a semi-truck that is blocking both northbound lanes at the bottom of Antler Hill, north of Innisfail. 

A semi-truck with a load of hay is said to be blocking both northbound lanes, so traffic is being re-routed through the area. 

Stay tuned for updates on traffic and emergency crew clearance.
