According to the Salt Institute the United States applied roughly 17,000,000 tons of road salt during the winter of 2013-2014. Other reports say that more than 20,000,000 tons of salt are applied on our roadways every winter.
To put that into perspective, that equates to:
- 124lbs of salt per person in the United States (there are 322 million)
- 158lbs of salt for every car or truck on the road in the US (there are 253 million)
- ~15x more salt than is used each year by the entire US food processing industry (source)
