Sugarloaf Road near the intersection of CO 119/Boulder Canyon Drive was damaged during the flood of September 2013. Boulder County made temporary repairs shortly after the flood. A new retaining wall system is currently being designed that will replace the temporary wall that is currently in place. Designs are in the preliminary stages. They will be made available on this webpage as soon as possible. Construction is anticipated for the spring of 2018.
There are currently no meetings scheduled.
- June 14, 2017 – Presentation of preliminary designs
Scope of Work:
The scope of repairs include, but are not limited to:
- Reconstruct 1890 feet of retaining wall where the slope is currently unstable
- Repair retaining wall where it is damaged but still stable
- Improve drainage by regrading ditches and adding new culverts
- Reconstruct 1930 feet of roadway to meed current county standards, which includes a 4-foot uphill shoulder
- Replace all guardrail (approximately 1580 feet)
The project is reimbursable by FEMA.
- Design and permitting – underway
- Anticipated bid release – Spring 2018
- Construction – Late spring 2018 through mid-summer 2018
Anticipated Travel Impacts:
- Alternating single-lane closures in place 24/7 for a few weeks during construction. Traffic signals will be used after working hours.
- Flaggers will be used during most of the project
- A lane on SH 119 may be closed to accommodate the retaining wall work.
- We are hopeful that traffic will be shifted onto the shoulder to reduce the need for the lane closure
CDOT plans to resurface Boulder Canyon Drive/CO Hwy 119 during the summer of 2018, so there may be some overlap between our work and theirs.
