After an extensive clean up process due to a rockslide, the Colorado Department of Transportation was able to partially reopen I-70 last night. CDOT says a pilot car is guiding traffic through Glenwood Canyon, but that they will be completely shutting down the highway again for more safety work. The plan now is to close down all lanes between the hours 9a.m. and 4p.m. for the next several days, until more rocks can be removed and the hillside can be better secured. During the periods that the highway is closed the same detour route will be used which again will send traffic through Northwest Colorado. CDOT is estimating that their crews have brought down about 400 tons of rock in the past week, in an effort to make the canyon safe for the single lane traffic pattern.
