DENVER, CO–(Marketwire – May 10, 2011) – ACH Foam Technologies supplied an estimated 2.1 million cubic feet of EPS Geofoam to the second largest Geofoam project in the US: the West Valley TRAX line. Utah Transit Authority (UTA) constructed the light rail line to a new hub in West Valley near Salt Lake City. Projected to cost $200 million and span 5.1 miles, the project required 639 truckloads or 750,000 cubic yards of the lightweight fill material. ACH Foam delivered the first truckloads in Febuary 2009; Geofoam installation was complete by January 2010.
A large landslide has closed SR 14 east of Cedar City, Utah. UDOT expects that the road will be closed for up to 2 weeks for cleanup and to ensure that the slope is safe. Boulders up to an estimated 20 tons are now blocking the road and will likely need to be blasted down to a smaller size. A UDOT spokesman interviewed on the video shown after the break estimate the size of the slide at 700 to 800-ft long and 10 to 12-ft thick.
A stretch of tunnel on Eastbound I-70 in scenic Glenwood Canyon Colorado was closed last March because of a 70-foot long crack in the ceiling. Since then the two-lane westbound bore has been handling both eastbound and westbound traffic while repairs to the damaged segment were undertaken. This project has a little of everything: heavy excavation, rockfall, slab reinforcing, geofoam, and even geogrid! Read on for more details, a map and photos. (Photo by Concrete Works Of Colorado)
