I've rebuilt at least 4 miles of bridges in N.H. and VT. The salt gets into a crack and then hits the rebar. In the old days the rebar was not coated.Salt damages the cars, not so much the roads.
You have to chip out ALL of the bad concrete and iron and patch the bridge. This is very expensive, time consuming and dangerous. Sometimes your 200 feet above a river or gorge. I get your point, butt there are many kinds of salt and they all do the same thing.
