Several methods are used to keep roads in good winter driving condition.
The City applies a mix of sand, salt and liquid calcium chloride to roads and walkways as required to maintain traction and/or melt snow and ice. The exact mix varies according to temperature and conditions.
Snow plowing begins on main roads after approximately 3 cm of snow has accumulated and more snow is forecasted.
After heavy snows, city neighbourhoods are bladed to a 5 cm snow pack after arterial and collector roads are cleared. Alleys are bladed before front streets. When activated, the Residential Blading Cycles begin on the same day each run.
As part of a pilot project, anti-icer (a calcium chloride solution with an added corrosion inhibitor) is applied to about half of Edmonton’s arterial and collector roads before snowfall. The product prevents the snow from sticking to the pavement, helping the roads to stay clear longer, and making snow removal easier.
