Statewide, Iowa — Snow is not in the forecast — but several big orange DOT trucks have been out on the highway with their sprayers going.
DOT winter operations director, Craig Bargfrede says they are spraying plain water, not salt brine.
He says all of the trucks are outfitted with a GPS system that is connected to the spreader controllers.
Bargfrede says most of the treatment they do now is a salt brine. They may sometimes put down some wet salt, but only for certain conditions. Bargfrede says they have developed a guide for the plow drivers for setting the material that is deployed.
He says they started earlier this month to get everything ready for when there’s actual winter weather.
Bargfrede says there is some early indication they may be busy.
Bargfrede says they will have the equipment ready, whatever Mother Nature throws their way.
