Thanksgiving week was met with a bit of seasonal snow, and ACHD crews met it head-on. We prepared for the little flurry of snow we received Wednesday morning the day before by applying magnesium chloride, an anti-icing agent, to the roadway. Magnesium chloride helps prevent a bond from forming between the pavement and snow/ice. That same material was still present on the roadway when we received a bit more snow on Friday. Our weekend on-call crews were called in at that point, and they worked on plowing and treating roadways through yesterday.
Sunday, the snow became more persistent, and our second on-call crews were called in at 6 p.m. that night and worked until 1 a.m. Monday morning, when they were relieved by the initial on-call crews. Crews used salt pre-wet with magnesium chloride and employed plows to clear snow and slush from the roads. As temperatures rose and snow turned into rain, much of the snow that remained began to melt.
Crews continued to monitor and treat their routes throughout the day Monday. The potential for more snow is being forecast for this weekend.
