The new concrete of St. Anthony Falls Bridge.


  “The St. Anthony Falls Bridge used about 50,000 yards of concrete. Hoover Dam used more than three million. And the Three Gorges project in China contains more than a yard for every man, woman and child in Canada, population 33 million.”


33 million yards of concrete is certifiably insane.  China’s at it again…

That new I-35W bridge in Minneapolis is beautiful.  The contractor has even built sculptures bookending the bridge that can actually sequester airborne carbon dioxide, thanks to a chemical additive that makes the concrete’s footprint “carbon negative.” They also include additives that scrub pollutants from the air, keeping the bridge bright white.
