ACHD taking on winter operations and last updated 2021-02-16 09:57:53-05 MERIDIAN, Idaho â Monday's new snowfall is not a concern, but all the snow that accumulated since Friday kept ACHD employees working around the clock to keep roads safe. âIn the more urban areas the roads are looking really good, but our crews are finding that the areas that are a little more rural are the areas that need to have a little more treatment so weâve doubled up on crews in that area,â said Natalie Shaver with Ada County Highway District. ACHD has 64 trucks capable of treating the roads, 46 plows to clear roads, and plenty of magnesium chloride and salt or salt mixtures to keep roads from freezing over. But with more snow expected later this week, donât expect snowplows on neighborhood or side streets.
