Des Moines, Iowa – It’s been sunny and relatively warm with temperatures in the 60s and 70s this week, but Iowa Department of Transportation employees are busy preparing for winter. Craig Bargfrede is the DOT’s winter operations administrator.
The agency’s 900 plows and other snow-moving equipment are being brought out of storage for tuneups and maintenance.
Over the summer, the Iowa DOT stocked storage facilities with nearly 230-thousand tons of salt to use on roads this winter.
In the coming weeks, even when it’s sunny and dry, Iowans may see DOT trucks spraying brine on roads and bridges. Bargfrede says it’s a “proactive approach.” Spraying brine on areas prone to frost prevents the formation of an icy layer, which typically occurs on cold, clear nights.
