No. The organic deicers have no chloride. The reason for using them is to minimize corrosion. The stuff is more expensive and the expense is justified, because it minimies corrosion. The only significant source of chloride would be what was picked up elsewhere and washed off the vehicles passing over the bridge.

Right you are. But, this bridge is 40 years old and organic deicers are relatively new.
