TRAFFIC ADVISORY: Gazex maintenance to cause closures on Berthoud Pass Friday

October 10, 2017 - Denver Metro Colorado/CDOT Region 1 - NORTH CENTRAL COLORADO — Starting Friday, October 13, Colorado Department of Transportation (CDOT) crews will perform routine maintenance on the Gazex system on Berthoud Pass.

As part of the operation, a helicopter will be used to transport oxygen and propane bottles to the Stanley slide area on Berthoud Pass to replace the bottles used last season, which will require a full road closure. This work must be done before a significant amount of snow accumulates on the mountain top.

This work is weather dependent and the schedule is subject to change.

Gazex is a system that improves how CDOT approaches avalanches while also improving the safety of its workers and the public. Instead of handling live ordinance, Gazex is a permanent installation on the mountain that uses compressed gases to create a concussive blast to trigger a slide.

The system is triggered remotely by operators from a secure distance, creating safer operations. All traffic will be stopped during the remote triggers and held until the roadway can safely be reopened.


US 40 Berthoud Pass: Up to 30 minute traffic holds between mile posts 247 and 250 on Friday, October 13, 8 a.m. to 3:30 p.m.
