Everyone knows you can recycle that old cereal box, your soda can from dinner and even a glass bottle, but what about a bridge? Yeah, you can recycle that, too. On July 10, MoDOT will demolish the Rte. 40 bridge and recycle 100% of the debris.
Built in 1966, the bridge is constructed of materials that are readily recycled today. After demolition, crews will retrieve:
* 2,578 tons of concrete, which will be used for base rock material or as rock ditch liner;
* 210 tons reinforcing steel, which will be collected and delivered to a recycler; and
* 579 ft of aluminum handrail, which also will be collected and delivered to a recycler.
"Recycling our materials is a priority in this job," said MoDOT Construction and Materials Engineer Perry Allen. "One-hundred percent of this bridge is recyclable and we plan to salvage all 100%."
Large-scale recycling is not a new concept for the department. MoDOT leads the nation in the number of recycled roof shingles added to asphalt mixtures. Other examples include:
* 325,000 tons of concrete and asphalt were recycled and reused during the reconstruction of a 10-mile stretch of I-64 in St. Louis;
* When the Rte. 19 Missouri River Bridge near Hermann was taken down, about 2,000 tons of steel from the structure was recycled;
* MoDOT has used enough recycled tires in its construction projects over the past two years to equip 20,000 cars;
* About 70% of state highway signs are produced from reclaimed material; and
* Using the latest technology, MoDOT can actually recycle entire asphalt roads.
The Rte. 40 bridge will be razed with a series of controlled charges. Beginning 12:01 in the morning on Saturday, July 10, northbound and southbound I-435 will be closed to all traffic until 5 a.m. Monday, July 12, so crews can salvage and remove debris.
Bridge demolition is part of the American Recovery and Reinvestment Act-funded project to add a third lane to I-70 in each direction and improve the interchange at I-435. It also will include removing and replacing the Blue Ridge Cutoff (George Brett) Bridge over I-70.
