According to Bridgestone Tire, road salt not only can rust your car, it can rust the road infrastructure. A well maintained roadway, with a full and sealed layer of asphalt, is your best defense against the possible damage of road salt.
“Automobile owners aren’t the only ones who need to worry about corrosion. Road salt can also damage bridges, parking garages, railroads, and other public transportation infrastructures. This corrosion damage is estimated to cost the highway and automobile industries $3.5 to $7 billion per year in the U.S.”
