ODOT's winter maintenance practices include plowing, sanding and applying liquid and solid deicers.
The combination of practices used may vary to accommodate the different climate, traffic and storm conditions.
ODOT's goal is to improve road conditions during and after a storm. However, it is always up to the motorist to drive according to conditions.
ODOT's winter highway maintenance practices reduce costs and limit impacts on natural resources while maintaining high standards for public safety -- our No. 1 priority. ODOT's standard practices during snow removal include:
Sanding material is sometimes applied on roads and bridges to provide better traction for safer driving. ODOT's practices minimize effects on natural resources by:
The use of deicer is an effective way to improve road surface safety during winter conditions. ODOT uses magnesium chloride (MgCl2) with corrosion inhibitor and solid salt (NaCl), both as an anti-icer before a storm to help prevent ice and snow from bonding to the road, and as a deicer after a storm to help break the bond between ice and road. Use of these chemicals has been proven to improve road conditions, reduce crashes and mobility restrictions and reduce the use of sand - which limits impacts on air quality, water quality and aquatic habitat. We continually strive to optimize application timing & rates of these products. ODOT uses:
We believe protecting the environment while providing a safe transportation system is a smart move. Plowing, sanding and deicing do not, however, make the road completely safe. Travelers have a shared responsibility to travel safely. Drive at speeds appropriate for road and weather conditions; consider delaying travel if necessary.
