Winter Maintenance - What’s New?
As we move into winter, MDT is at work to keep the traveling public safe. You’ll notice a few new additions this year for winter maintenance...
MDT now has 19 tow plows statewide that are ready for action! Find out more about these powerful plows that can clear twice the snow with one plow!
Snowplow cameras are back! There will be 12 camera locations this year, and the images will publish to the interactive travel map when the plows carrying them are active. The snowplow cameras have also been added as a layer to the Travel Info map, and will be available on the web and using the mobile app.
The new Capital/Cedar Interchange bridge on I-15 is equipped with an automated de-icing system. The system installed is a strip and nozzle system, and the bridge houses about 100 nozzles. Prior to the roadway freezing, the system will activate and spray anti-icer on the bridge. Potassium acetate is the chemical that will be used and is the same chemical that is used to anti-ice airplanes. It is environmentally safe and is not corrosive. The amount of chemical used will be no more, and in most cases, less than what is currently used. The traveling public should be aware that the system can be activated at any time it senses a freezing event. This includes while traffic is moving across the bridge. When there is not a freezing event for 7 days or longer the system will activate periodically in maintenance mode. This is to prevent plugging of the nozzles when the system has been idle. During the spring, summer and fall months, when the temperature is well above freezing, the system will be in maintenance mode. It will activate 2-3 times / month with straight water to flush out the nozzles so as to keep them in good operating condition.
