St. Charles County snowplow drivers prepare for the challenges of clearing streets. Ashley Harrellson, 38, a Highway Street Maintenance Worker with over two years of experience, readies herself for long shifts with coffee and sandwiches. Speaking to St. Charles County Government, Harrellson noted the satisfaction of her work, saying, "I like when you're driving and there's all snow ahead of you, and then you have your plow down and you're throwing salt, and you look behind you and it's all clear."
St. Charles County snowplow crews work in shifts, covering roads from dawn to dusk or overnight to keep streets clear. Michael VanBuren, a 12-year veteran, said unpredictable weather often requires quick responses. The Highway Department, led by Superintendent Ted Dunkmann, is equipped with 18,000 tons of salt, 50 snowplows, and sufficient staff to maintain the county’s 1,700 lane miles every half day.
An online Snow Route Map allows residents to track snowplow progress in real time. The Highway Department adjusts its strategies based on storm conditions, avoiding pretreatment with salt brine when rain is expected.
After winter, the Highway Department shifts focus to other roadwork, including maintaining rights-of-way, paving asphalt, replacing concrete street pads and sidewalks, performing storm sewer work, trimming trees, and mowing rights-of-way.
