Local agencies across Michigan are preparing for what could be better than a 40 percent increase in salt costs this winter, which is also expected to be early and harsh.

The County Roads Association of Michigan says the price of salt has risen steadily over the past decade while revenues have been on a downward slide. The statewide average is expected to run nearly $66 per ton of road salt for the 2014-15 winter season, up more than 46 percent from last year.

CRAM director Denise Donohue says the harsh winter last year caused many road agencies, and other public entities that cooperatively purchase salt from them - such as school districts and other governmental agencies - to deplete their salt reserves. She adds that as the demand for early salt delivery increased this year, so did the price.

The association also said because of the unusually harsh winter last year vendors weren't able to adequately stockpile a supply.
