I know the freeway salters already use a thick slurry salt mix that not only speeds the melting process, but also stays put alot better on bridges and such. I don't know what is exactly in the mix, but i seem to recall the mix is just as safe as pure salt.
Other than cost savings though, I wouldn't call it a eco benefit. It's still going to wash away into the ground and local water, I remember a article in the Milwaukee journal a few years back that some of the smaller ponds and lakes in the Madison area were starting to show a dangerous salinity level for the local wildlife. (they tend to over salt the roads a bit according to the article)
I live in the Northwoods, and what the county does here is salt right after the snow ends, and after that it's sand. a bit more economical, they just send a street sweeper out early spring and collect what hasnt washed away and reuse it
