Sunshine Canyon and Flagstaff Opening; Bike Resident Access Cards Available for Pick-Up

Boulder County, Colo. – Due to the recent progress by CDOT and County Transportation Department crews and contractors, as well as the successful temporary opening of Sunshine Canyon last Sunday, Boulder County will open up both Sunshine Canyon and Flagstaff Road to all users at all times starting on Saturday, Nov. 16. As committed, the county has monitored and conditions on these roads and, due to the recent progress, will be opening the roads to all users.

With the re-opening of SH72 in Coal Creek Canyon by CDOT and the anticipated completion of most of the emergency shoulder repairs on Flagstaff by County Road Maintenance by the weekend, there will be less commuter traffic on Flagstaff, and the road will be safer for all users. For Flagstaff to remain open for all users, it is important that everyone complies with the one lane signal where the road has been washed out.

Sunshine Canyon is now open to all users with completion of the two-lane temporary winter access road along 4 Mile Creek between Boulder Canyon and Salina. The opening of the 4 Mile winter access road should reduce construction vehicle traffic on Sunshine Canyon and Poorman Roads.

What: Cycling allowed in Sunshine Canyon and on Flagstaff Road.
When: Indefinitely, starting Saturday Nov. 16
Who: All motorists and cyclists allowed
Where: All of Sunshine Canyon and Flagstaff Road

These roads will be open to cyclists and motorists for the foreseeable future, save for situations in which dangerous conditions or further significant road reconstruction requires temporary restrictions. Those closures will be posted when the schedules of repairs are finalized.

Bicyclists living on restricted access roads may obtain a bike resident access card that allows legal access the road. The resident access cards are available for cyclists who use their bikes as their primary mode of transportation and use restricted access roads for access. Visit the Boulder County Sheriff’s office to obtain a permit.

Boulder County Transportation Director George Gerstle said “We would like to thank everyone, motorists and bicyclists alike, for their patience while we repair the county roads as quickly as possible. We will be asking for even more patience and understanding when we ask everyone to avoid certain roads for limited times as we continue our work to fix the county roads. We want to remind all residents that while we are making progress on repairing the roads, we still have more to do (please refer to for updates), and may have to periodically restrict travel on some roads during periods of construction and repair.

“During this challenging recovery phase, please be considerate of affected residents and stay out of heavily damaged areas. Everyone is working hard to recover and rebuild, and we ask that people respect their work and stay away from damaged areas of the county unless there is a good reason to be there.”

Jtown, et al.

Thanks CDOT and County workers for making this happen relatively fast, even though it feels like forever ago!

Not to sound ungrateful, but I havent heard any updates about progress on Lefthand,Canyon and the forks to Jtown and Ward, Old Stage opening, etc. I presume work is happening but any progress updates to report there? How about South St Vrain (hwy 7) out of Lyons as well?

Canyon & Lyons residents, I hope you are also making forward progress in rebuilding your lives, although I'm sure it's a long and winding road. Stay CO Strong!

I drove lefthand and based on

I drove lefthand and based on what I saw, I wouldn't hold my breath for the road to be back to normal anytime soon. The destruction west of the fire station is breath taking. I did not see the damage east of jamescanyon. I was able to drive to ward and peak to peak. I did turn around before south st vrain. Road worker said if I didn't have access permit that I wasn't allowed down south st vrain. I didn't see any significant signs of repair on lefthand being done. It looked like the road was cleared safely enough so that cars could pass but no road repair.
Lee hill and old stage are absolutely rideable but the problem is lefthand. I guess the county wants to keep these roads that feed to lefthand closed to cyclists until lefthand is repaired. I'm just grateful that flagstaff and sunshine are open.
