A section of the QEII Highway north of Calgary was shut down on Wednesday after a collision.
The incident forced the closure of the northbound lanes of the QEII at the Carstairs overpass at Highway 581.
A tweet from 511 Alberta reported the closure just before 10 a.m., saying it was due to a jackknifed semi-trailer.
A Facebook post from the Carstairs Fire Department said traffic in the area was being detoured, and that the road was “very icy.”
