Traffic was backed up in Saskatoon’s north end following two separate collisions Wednesday evening.

Emergency crews responded to a 10-vehicle crash on Circle Drive, about one kilometre west of the Circle Drive north bridge, as well as a three-vehicle collision on Warman Road, south of the Circle Drive ramp.

The 10-vehicle crash, which occurred in the eastbound lanes, blocked two of three lanes and backed up traffic past Millar Avenue. Police described the collision as a chain reaction involving numerous rear-end crashes. Four pickup trucks, five cars and a semi were involved in the incident. No one was injured, police said.

The Warman Road crash left only one southbound lane open to traffic. Police said a vehicle turning onto Warman Road from Hazen Street collided with a vehicle travelling northbound on Warman. A third vehicle waiting to turn was also hit.

A 19-year-old woman suffered head injuries and a 64-year-old woman suffered minor injuries, according to police. A 21-year-old man was charged with leaving a stop sign before it was safe to do so.
