Colorado Department of Transportation crews are performing rock scaling work at Vail Pass on Interstate 70 this week [1, 2].
These operations are necessary to prepare the area for the installation of avalanche fencing. This safety project aims to reduce the risk of snow slides and debris impacting the highway, which serves as a critical transit artery for the region [1].
The current work involves the removal of loose rock from steep slopes to prevent natural falls from blocking the roadway. Because of the precarious nature of the terrain, crews must operate in close proximity to active traffic lanes [1, 2].
Motorists should expect delays as periodic lane closures in both directions will continue through next week [1]. These closures are scheduled to facilitate the safe movement of heavy machinery and personnel along the mountain pass [1].
While current efforts focus on rock scaling and fencing, other reports indicate that broader auxiliary lane construction projects in the area are entering their final year of development [2]. The combination of these efforts is intended to modernize the infrastructure of the pass, and improve overall driver safety during winter months [1, 2].
Travelers are encouraged to monitor local traffic reports for real-time updates on lane availability. The Colorado Department of Transportation said the disruptions are expected to be intermittent throughout the coming days [1].

The ongoing work at Vail Pass represents a critical intersection of geological mitigation and winter weather preparedness. By combining rock scaling with avalanche fencing, the state is attempting to address two distinct hazards—falling rock and snow slides—that frequently disrupt I-70. These short-term traffic disruptions are a trade-off for long-term reliability on a route prone to extreme weather and terrain instability.
