Expect delays on November 2 and 3 from 9 a.m. to 3 p.m.
Boulder County— The first phase of safety improvements on Colorado Highway 119 will begin Nov. 1 with the installation of rumble strips on the outside of the shoulder line from approximately Hover Street in Longmont to Foothills Parkway in Boulder.
The overall project will take 10 business days to complete and will begin with the rumble strips which are expected to be completed by November 3. Machining of the rumble strips will be performed during the day, from 9 am to 3 pm, using a slow system. -Single lane closure in motion. Traffic delays can be expected.
During those two days (which could possibly also happen overnight during non-peak hours), cyclists are strongly advised to avoid CO 119 because the right lane and shoulder will be blocked and impassable.
Once the stripes are in place, the project will add safety signs at intersections to alert drivers about cyclists in the area. This work is expected to be carried out from November 13 to 16 and will have sporadic lane and shoulder closures. Cyclists are also strongly encouraged to find new routes during this time.
Rumble strips provide an audible and vibration warning to drivers who may be leaving the road. The stripes will be installed along the outside shoulder edge line along the corridor where there is adequate space for their installation and still allow bicyclists to use the shoulders. No rumble strips shall be placed within 250 feet of any residence or business.
Next spring, work will begin on the broader aspects of CO 119's safety and mobility improvements.
Background
By 2040, the Diagonal Highway between Boulder and Longmont is expected to see a 25 percent increase in vehicle traffic, which can result in more congestion, delays, emissions, and potentially more crashes. The Colorado Department of Transportation and the Regional Transportation District are taking steps to mitigate these outcomes and expand transportation options beyond vehicles.
The CO119 Ciclovía and Safety and Mobility Improvement Project will provide improvements to make travel through the corridor safer for all modes, as well as faster and more reliable for public transportation. It will provide critical intersection safety improvements, build a regional bike path, and implement Bus Rapid Transit (BRT), connecting Larimer, Weld, and Boulder counties.
Project improvements include:
- pedestrian crossings
- New signage
- lined
- Improved signal synchronization
- Intersections
- Reconfigure CO 52 Intersection into a Split Intersection
- Safety improvements and access changes to the Airport Road intersection and other unsignalized intersections in the corridor
- Reconstruction of the Hover Street intersection
- Commuter bike path
- 9 miles of 12-foot-wide concrete path separated from the road
- 6 underpasses with pumping stations
- Level crossings at major intersections
- Direct connection to existing BRT stations and bicycle networks
- Lanes to avoid queues
- Jay's Way
- CO 52
- 63rd street
- Niwot Highway
- airport road
- Park and walks
- Bus rapid transit stations
- 63rd street
- CO 52
- Niwot Highway
- Foothills Pkwy/47th Street
Money
Funding has been secured for the implementation of the project, with construction expected to begin in 2024. CDOT, RTD, Boulder County, the City of Longmont, and the Denver Regional Council of Governments (DRCOG) have committed $115 million toward construction .
