Smog Running Scared

Beginning this week, St. Louis smog is running scared - not because of Halloween tricks, but due to some very hungry new concrete.

On Monday , a new smog-eating concrete was poured in St. Louis. It's being tested on a 1500-foot stretch of the new Route 141.

The concrete contains an additive that absorbs smog, uses sunlight to break it down and releases it as nitrogen and carbon dioxide.
