Colorado Highway 119 Boulder Canyon full closure for safety blasting Oct. 19

BOULDER Colorado Highway 119 will be closed from Milepoint 39-40 on Saturday, Oct. 19, at 8 a.m. through Sunday, Oct. 20, at 8 a.m., allowing project crews to safely remove a potentially unstable rock ledge above the Boulder Canyon. 

This 3,000 cubic yard blast is necessary to ensure the safety of Colorado 119 users, and will require more clean-up than the regularly scheduled daily blasts. 

In light of the start of the school year and bus operations, the Colorado Highway 119 team has scheduled this extended full closure over a weekend to minimize impacts as much as possible.

During the extended closure, travelers are urged to avoid the Boulder Canyon route,] if possible. Local detours are available. From Boulder, a northern alternate route can be taken via CO 7, US 36 and CO 72. A southern alternate route is available via CO 93 and CO 72. Please note, motorists taking the southern alternate route should be aware of a current project on CO 72 in Coal Creek Canyon, between Plainview Road (mile point 12.3) and Pinecliffe (MP 24.6). A detour map is included below. Expect lane shifts and short delays at this work zone.
