Whitemud Drive Flooded and Closed Due to Severe Storm Runoff
Rising water levels turned sections of Whitemud Drive into lakes on Saturday night, trapping drivers and prompting emergency responses. According to Global News and eyewitness reports, the 170 Street underpass flooded significantly, deploying firefighters to help people stuck on the side of the embankment between the northbound and southbound overpass bridges. Vehicle traffic was forced to turn around on one-way freeway lanes, and side ramps became impassable. Three vehicles became stuck at the eastbound 170 Street off-ramp where a dip in the road collected around two feet of water. Edmonton police announced around 10:30 p.m. that the entire Whitemud Drive was closed between 156 Street and 178 Street, advising drivers not to travel unless necessary.
