Glenwood Canyon East Rock Scaling

April 18, 2011 - Northwestern Colorado/CDOT Region 3 - Traffic holds, delays east of Hanging Lake Tunnel April 20th and 21st.

GLENWOOD SPRINGS – In an effort to further reduce the potential for rockfall in Glenwood Canyon, the Colorado Department of Transportation and contractor Yenter Companies will complete two days of rock scaling (using pry bars to bring rocks down by hand) over I-70 at MP 128.9 (just east of the Bair Ranch Rest Area.) The cost of this preventative maintenance work is $5,100.

TRAVEL IMPACTS: On Wednesday and Thursday (April 20-21), motorists will encounter single-lane traffic in BOTH directions near the work zone, as well as full traffic stops while rocks are brought down. Crews will make every effort to keep these holds to 15 minutes or less, but delay time will depend upon safety, as well as traffic volumes and the time it takes to clear queues in each direction. Traffic control will be set up for westbound lanes at 7 AM, and for eastbound lanes at 8 AM – the work is likely to last until 7 PM each day. Thank you for going Slow for the Cone Zone!
