I-70 through Glenwood Canyon will remain closed at least through midday tomorrow following a rock slide that damaged the roadway and left massive boulders on the highway. The Colorado Department of Transportation plans to begin moving traffic though the canyon sometime tomorrow by operating a single-lane alternating traffic pattern that could remain in place for several days while repairs and rock stabilization continues. Yesterday, crews began the process of evaluating the walls of the canyon and removed boulders from the eastbound lanes. The problems in Glenwood Canyon began after an initial rock slide occurred early Monday morning creating delays, but did not close the highway. A subsequent and much larger rock slide occurred Monday night, closing the road to all traffic. Until the single lane alternating traffic plan starts, vehicles will continue to be detoured through Meeker, Craig, Hayden, Steamboat and Oak creek. A multi vehicle accident on rabbit ears pass yesterday, compounded traffic problems in the area when the pass was closed for about 2 hours for accident clean up. Photos courtesy of CDOT.
