Does Chicago salt their roads in the winter?

[Tenzo]

1) It is illegal to salt the streets in Chicago

It is unlawful for any person to spill, pour, drop or place, or to permit the spilling, pouring, dropping or placing upon any asphalt or bituminous pavement laid upon any public street, court, alley or place within the city, and oil, petroleum, kerosene, benzine or other similar oil, or oily substance, or liquid, or any salt, rock salt, common salt, salt brine, acid, chemical, broken glass, or any injurious or destructive material which might damage such pavement.

2) Yes they salt. LOTS

And stainless steel most certainly does rust when exposed to a combination of salt and water long enough and often enough. All the 15-year-old rusting hulks you see plying the streets of various northern locales are made of stainless steel.

If you're talking about cars, they are most certainly not made out of stainless steel. This would make scrapping them worth thousands of dollars, vs. the $240 a ton for regular steel that is being paid now.

Right, as IT29 points out I was confusing galvanized with stainless. Nevertheless, stainless steel is still prone to rusting when exposed to salt and water. Obviously it is more resistant to corrosion than plain ol' iron, but to say it "does not rust" isn't quite accurate. It just takes longer to do it.
