Spring Road Projects affecting Cyclist in Boulder County

From Boulder County Transportation
Attn: Boulder County Cyclists!!

Construction season is here and Boulder County has a couple of large projects going on now that were put on hold when the flood hit last September. Also, flood repairs are due to start on Flagstaff Road.
51st Street Reconstruction – Jay Road to the Boulder Reservoir.

Boulder County has started construction on 51st Street from Jay Road to the Boulder Reservoir. Originally scheduled for last September, this project is now underway and should be completed by May 15. The project includes removing the old pavement, re-establishing the old road shoulders and re-paving the entire length of the project. A new connection between the Diagonal Highway (SH119) and “old” 51st Street will be installed as part of the project. Cyclists should exercise caution while using the roadway especially as the top layer of pavement has been removed.

Please reply to this email if you’d like to be added to the project notification list.

63rd Street / Jay Road Intersection Repaving.

Boulder County contractors will be re-paving the intersection of Jay Road and 63rd Street starting Wednesday, April 23 and continue for one week. Surface will be milled asphalt during that period.

Highway 119 Underpass at Airport Road – includes new concrete sidewalk along Airport.

Boulder County is starting construction on a new bicycle and pedestrian underpass crossing of the Diagonal Highway at the current intersection with Airport Road. Users of the Highway should see some construction activity starting next week. All lanes of the highway will remain open and a bicycle shoulder has been included in the “shoo-fly” detour pavement. Ogallala Road will be CLOSED at the Diagonal Highway starting Monday May 5, and lasting for much of the construction period. The project is scheduled to last through the end of December.

The current underpass and sidewalk design is available for viewing on the Boulder County website. Please reply to this email if you’d like to be included in construction updates on this project.

Lefthand Canyon / James Canyon Debris Project – No bikes Until May 1.

Boulder County contractors are clearing debris from both Lefthand Creek and James Creek. Due to unsafe conditions Boulder County is now restricting access for cyclists through May 1. Residents requiring access by bicycle should contact the Boulder County Sherriff’s office for a permit. Full details are available on the County website.

· Highway 93 Shoulders – Construction continues through mid-September.

CDOTs work on the Highway 93 south of Boulder continues. They have made good progress with both adding shoulders to the highway and the new underpass to carry the Community Ditch Trail under the highway.

The latest construction schedule has the project continuing through mid-September. The trail crossing is currently closed and is likely to remain so throughout the summer. We’ll let everyone know as soon as it is opened.


All schedules are subject to change due to weather or other factors. Please use caution when riding and remember, "Courtesy is Contagious"!!!!

News Item: 


Highway 7 barriers and shoulders

At the usual downhill speeds on Hwy 7 (South St Vrain canyon), it's pretty hard to use the shoulders anyway between sand and debris and wind. If you're going downhill, especially around corners, use the lane.

On the barriers, I would guess they will be there for a while because there is not as much stream bank as there was before, and DOT probably wants to prevents cars from going into the creek.
