Avalanche Mitigation on I-70 starting March 10, 2019

HEADS UP! Safety critical helicopter operations will begin tomorrow, Sunday, Mar. 10 in order to perform avalanche mitigation at several slide paths along the I-70 corridor. The areas impacted are as follows:

8:30-9:30 a.m.: Mission on Big Marvin slide path on Vail Pass (mile point 186)

11:00-Noon: Mission in 10 Mile Canyon (mile point 196 east of Copper Mountain)

1:30-2:00 p.m.: Mission on Silver Cloud and Bard Shoulder slide paths in Silver Plume

Due to the dynamic nature of this work it is impossible for CDOT to estimate how long these closures will take place. The Colorado Avalanche Information Center has identified many mountain ranges in western Colorado as being at high risk for avalanche slides. It is very likely that a natural slide could occur and motorists should plan for unexpected closures as well.

There is also the possibility of large debris fields with trees and rocks mixed with snow in these slides which can take maintenance operations longer to clear.

Should you encounter an avalanche or powder cloud while driving.
-Reduce speeds
-Pull over to shoulder if possible
-Turn off your vehicle
-Remain in your car
-Call 911 and request help
-Make sure you are prepared with an emergency kit and adequate traction. An emergency kit should include: jumper cables, flares or reflective triangles, ice scraper, car cell phone charger, blanket, map,cat litter or sand for traction, food and water.
