Statue Absorbs Pollution

Two 30 foot statues looking like the international symbol for water have been erected on Minnesota’s I-35W bridge. Not only is it appropriate considering it’s on the Mississippi River, it’s made of a photocatalytic concrete…meaning it can use ultraviolet light and make the exhaust out of your car less damaging to the environment. Gases such as carbon monoxide, nitrous oxides, and sulfur dioxides will be put into a higher oxidized state causing less damage. It basically works like an outdoor catalytic converter. Aesthetically, it will never look old and will always keep that white finish.
