James Canyon & Logan Mill Updates – Traffic Signals & Paving

From Andrew Barth, Boulder County Transportation


The contractor, Kelley Trucking, Inc. (KTI), informed me that they will need to utilize traffic signals (24-7) starting tomorrow just below Jamestown so they can safely install a rockery. The signals will need to remain in place through the Fourth of July holiday, even though KTI will not be working on July 4 and 5. We’ll try to get them down so you can enjoy a travel delay-free holiday in the canyon, but it may not be possible. Crews will work on Friday, July 6, and there’s a possibility they’ll need to work on Saturday, July 7 if the road needs some last minute prep before paving starts on July 9.

Travel delays will remain in they 15 to 25 minute range during working hours, Monday through Friday, until paving starts.

Asphalt removal operations should end this week. KTI will continue working on prepping the the subgrade and placing road base in the sections where asphalt has been removed over the next several weeks.

Phase I paving, between the confluence/junction and the large retaining wall below town will start at 8 a.m. on Monday, July 9. Work will last until 6 p.m. on Monday, and then the schedule will shift to 7 a.m. to 5 p.m., weekdays, through July 20, when they expect finish this section. Expect long delays (30+ minutes) during paving and a lot of heavy truck/equipment activity. After Phase I is complete, Phase II paving operations will move above town starting on or around July 23. Phase III will start soon after Phase II has ended, sometime around August 13. This will be the final stretch of paving through town.

In addition, Work on the last retaining wall at the Logan Mill flood recovery project site is underway. In order to complete the work, the contractor will need to reduce Fourmile Canyon Drive to one lane at the intersection with Logan Mill in order to safely accommodate the equipment that will drill the caissons along the road that will form the wall.

A three-way traffic signal will be in use 24-hours a day, seven days a week through July to safely move travelers around the work zone.

The signals will be equipped with sensors that will detect vehicles stopped at the light in order to speed up the wait. Please do not run a red light. Not only is this dangerous, but it will also trip the signal and set the unit into a default timer setting which will create a longer wait for the next few cycles while the system resets itself.

Please let me know if you have questions.

Have a good day and a great Independence Day!
