Travel Advisory

February 5, 2019 - Jefferson County

The Colorado Department of Transportation (CDOT) will close US Highway 6 in Clear Creek Canyon between Colorado Highway 119 and Colorado Highway 58 this afternoon (Wednesday, Feb 5) beginning at 3 p.m. to repair the rockfall netting just west of Tunnel 1.

Incident Background

Early in the morning on Wednesday, Feb. 5, a rockslide occurred just west of Tunnel 1 on US 6 in Clear Creek Canyon. Due to rocks on the roadway, a safety full closure was put in place around 4:30 a.m. 

CDOT’s Geohazards Team responded to assess the slide, and deemed it safe for CDOT Maintenance to begin the cleanup around 7 a.m. Once all rocks were cleared, crews found damage to the pavement that was repaired at that time. The road safely opened back up just before 9 a.m.

As a next step in rockfall mitigation at this site, CDOT Geohazards will return this afternoon to repair the rockfall netting damaged by the slide. They will also continue to assess the site to determine if further mitigation is needed. This is happening today beginning at 3 p.m., resulting in a full closure of US 6 between CO 58 and CO 119.


The full closure of US 6 during this work is necessary for the safety of the crews and the traveling public, as there will be various pieces of machinery in a narrow canyon area. The closure is expected to last four hours or longer.



  • Drivers can take I-70 both eastbound and westbound as an alternate route around the closure.
