I'm not an engineer, but it could be because the road salt deteriorates the concrete, rebar, or the iron supports of the bridge. I'm probably completely wrong, and the road crews are just lazy, or the city just doesn't care. Or, they're concerned about the salt being so close to the river, even though in the end, all the road salt they dump will eventually find it's way back into the water system one way or another. And when they salt things, it's overkill... they dump 3x as needed, and spill it everywhere. It's nasty shit, and causes a lot of damage to the environment. In most Canadian cities, you rarely see grass growing near streets... salt kills it all.
