From the Great Salt Lake to Herriman, here's a mound of 350 tons of salt used to de-ice roads on cold and snowy winter days or nights. Herriman City snowplow crews keep a stockpile that is constantly refilled to ensure they always have the salt they need to get the job done. The salt lowers the freezing point of water, which prevents ice from forming and makes it easier to melt existing ice and snow. | Herriman City
