June 15, 2017 Project Update – Expect ongoing delays
KTI has begun installing cross-culverts under James Canyon Drive. Work started at the Lefthand Canyon end of the project and will progress towards Jamestown. This work will require single-lane closures between 7 a.m. and 6 p.m., Monday through Friday. Flaggers will be used to move travelers safely around the work zone, so expect delays of up-to 10 minutes. They will likely be shorter. Asphalt will be removed from both sides of the road in order to install the new culverts, so please use caution when traveling through this area.
In addition to the road work, stream work will commence around the same location and proceed west towards Jamestown. Expect delays when vehicles and equipment are entering and exiting the roadway from the stream area. These delays should be short and infrequent.
Please allow yourself more time to safely arrive at your destination during working hours (7 a.m. to 6 p.m. – Monday through Friday).
Anticipated Travel Conditions During Construction
- These conditions are anticipated to start the week of June 12, 2017 – weather permitting – expect short (1-2 minutes), infrequent delays until then
- The road will be reduced to 1 lane in multiple locations. In some spots, the lane closure will be in place 24-hours a day, seven days a week.
- There will be no full-time closures of the entire road.
- Lane closures will be managed by flaggers and by traffic signals.
- Traffic signals will be timed to allow the slowest traveler (usually cyclists) to safely pass through the construction zone.
- Please do not run red lights. They will be enforced just like normal traffic lights by the Sheriff’s Office.
- Working Hours
- March 1 to Oct. 31 – 7 a.m. to 6 p.m.
- Nov. 1 to Feb. 28 – 8 a.m. to 4:30 p.m.
- Monday through Friday – NO WEEKENDS
- No work will take place during federal holidays (Memorial Day, 4th of July, Labor Day, Thanksgiving, Christmas, New Years, etc.)
- Project expected to last through December 2018
Communication During Construction – How to stay informed

- Information will be posted on the Jamestown, Bar K, and Ward QT websites.
- Questions, comments and concerns can be directed to Andrew Barth at Boulder County Transportation
In September 2013, 17 inches of rain fell throughout Boulder County. One of the hardest hit areas was James Canyon. The rain and corresponding flooding destroyed much of the road through Jamestown and almost everything through James Canyon and permanently altered James Creek. Shortly after flood waters receded, Boulder County got to work and built an emergency access road into town to help get people some much needed relief and supplies.
Soon after the emergency road was built, the county returned and created a temporary “winter road” that allowed for access beyond high-clearance 4WD vehicles. This road remained in place until the summer of 2014 when a temporary asphalt surface was applied to the gravel sections of the roadway. The asphalt surface was applied so that area residents and service providers had a safe road to drive on while they completed their own flood recovery-related repairs and so that Boulder County and their engineering team could work on a permanent design for a roadway that would be safer for all travelers and one that would be resilient towards future flood events.
- Construction Start Date = May 15, 2017
- Anticipated End Date = Winter 2018
