Late Friday evening, Airdrie RCMP confirmed that lanes were re-opened after a multi-vehicle collision near Crossfield. 

A multi-vehicle collision on the QEII Highway, heading Northbound near Crossfield at Township Road 285 had shut down traffic for a few hours on Friday evening.  

Eyewitnesses said that a jack-knifed semi is blocking the northbound lanes.

Earlier on Friday, over two dozen vehicles were involved in a collision East of Carstairs. One woman in her 80's was injured and taken to hospital.
