GLENWOOD SPRINGS - Barring any further weather impacts through the night, CDOT crews anticipate opening I-70 Glenwood Canyon by daybreak on Friday, Aug. 20. Crews were encouraged by how well the canyon landscape weathered over three inches of rain that fell over a 24 hour period.

The National Weather Service forecast calls for continued precipitation to dissipate in the early morning hours. Crews have already commenced cleaning up three small material slides in several areas that have seen activity before.

The Colorado Department of Transportation closed Interstate 70 in both directions through Glenwood Canyon at mile points 133 (Dotsero) and MP 116 (Glenwood Springs) at 4:20 p.m. on Aug. 18 due to a Flash Flood Warning issued by the National Weather Service. 

Rain gauges throughout the area measured over three inches of rain in several locations. CDOT will continue to follow the same standard traffic safety and detour procedures that have been in place during the previous closure as forecasts dictate. The repairs in Glenwood Canyon have held up through this weather event so far. 

Muddy water covers the roadway
