Hidden Cost of Road Salt

I have been very concerned about the use of salt on our Heath roads for a number of reasons: (1) the deterioration of our roads, (2) deterioration of our highway vehicles and our personal vehicles, (3) the  environmental impact of salt washing into our streams,  (4) the added costs of replacing our plows and trucks due to corrosion, and (5) the added cost of replacing the salt shed with material impervious to salt corrosion (apparently concrete is not.)

I understand that sand has drawbacks and does not give us those clear, albeit "whitish" roads, but I  think we should at least understand the hidden costs of salt vs sand and decide if we can afford it.   When I first moved to Heath in the pre-salt days, I used to brag to friends, "Once you get to Heath, the roads will be fine." And they were.  

I did a lot of research and found this article more relevant to Heath than the Mass DOT site.
