Salt gets spread on existing ice to melt it all the time.  Where does the absorbed water go in this model?  This assertion is so confusing.&lt;p&gt;As someone who grew up in a cold climate, the way I recall it is that the salt lowers the freezing point of water by forming a brine, allowing it to run off the road and&amp;#x2F;or be evaporated by the sun.</text><parent_chain><item><author>CivBase</author><text>Many places in the midwest have actually switched away from using salt to melt snow because it does a lot of damage to concrete and vehicles.

The only times I&amp;#x27;ve seen the midwest US use sand instead of salt is when the temperatures are below where salt is still effective.&lt;p&gt;Do you have a citation for this statement, because it is 100% the opposite of what I see in my day-to-day life.</text><parent_chain><item><author>CivBase</author><text>Many places in the midwest have actually switched away from using salt to melt snow because it does a lot of damage to concrete and vehicles.
