Me Want Smog!

Nom, nom, nom ... this concrete doesn't care much for cookies, but can't resist a nice batch of smog.
MoDOT and contractor Fred Weber Inc., will test a new type of concrete on a section of Route 141 in St. Louis this month.

A new additive which breaks down smog will be added to the stretch. The additive absorbs smog, uses sunlight to break it down and releases it as nitrogen and carbon dioxide.

Stay tuned for the result!
