Winter weather impacts rock blasting completion in Boulder Canyon

BOULDER — Due to the winter weather conditions that hit Boulder Canyon this week, final rock blasting on Colorado Highway 119 has been rescheduled for Feb. 12 and Feb. 13 from 10 a.m. to 2 p.m. 

CO 119 will be closed between Mile Point 39 and MP 40, from 10 a.m. to 2 p.m. each day, while rock blasting operations occur, in order for the work to be completed as safely and efficiently as possible.

Moving quickly on these blasts will allow crews to open the road to two-way traffic in advance of a number of community activities in the area, including Frozen Dead Guy Days in mid-March in Nederland. 

Snow and ice conditions made the rock face unstable for blasting operations and created an unsafe work environment for the crews and traveling public, so the work was rescheduled. 

“Colorado winters are often unpredictable, as we all know, and we experienced it first-hand this week. At the end of the day, we want to make sure we’re doing our part in keeping the traveling public and our crews safe,” said Jared Fiel, communication manager for CDOT Region 4.

Rock blasting is weather-dependent, which impacts work duration and overall project completion. Please refer to the project contact information below for the most up-to-date information. Should winter weather or other unexpected conditions occur, rock blasting activities will be rescheduled.    

What’s Next

Once rock blasting is completed, drivers can still expect to encounter travel delays with ongoing efforts to remove loose rocks and material from the slopes above the highway throughout February and March. Because this rock scaling work involves pushing large boulders onto the roadway below to prevent natural rockslides, traffic will be stopped in both directions for several minutes while this work is done and the roadway cleaned up. Traffic queues will then be cleared in both directions before vehicles are again stopped to continue scaling work. Drivers should plan for delays of about 20 minutes.  

In addition, drivers can expect single-lane closures to resume in April for river armoring and roadway reconstruction work. These single lanes will be ongoing throughout the summer and fall.

There is also the possibility that four to five four-hour full closures will be required to complete the pedestrian path extension for Boulder County. 

Construction is scheduled to be complete late 2020. However, weather could impact planned paving work. Paving operations require certain temperatures to ensure the quality of the asphalt. If weather affects the current schedule, paving will be done in spring 2021. 

Drivers should continue to check the project website, email updates and hotline for the most up to date travel information. See contact info below. 

TRAVEL IMPACTS 

Local detours remain 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). Expect lane shifts and short delays at this work zone. 

Anyone wanting to receive text alerts about this project and the closure can text CO119 to 21000.
