Commuters that use a busy Calgary highway needed to find a different route on Wednesday following an early morning crash. Officials said a vehicle rolled on Crowchild Trail around 5:30 a.m. The incident appears to have knocked down a power pole in the area. No other vehicles were involved. “At this time, northbound Crowchild Trail is closed between 17 AVE and 33 AVE S.W. We are asking drivers to avoid the area,” Calgary police said in a statement. There is no information on any injuries because of the crash. As of 8 a.m., traffic was still blocked.
