Repairs to Begin to Upper CO 7
Three-Day Intersection Closure at 7E North

In conjunction with the culvert work on CO 7 and 7E, ACC will close the northern intersection of CO 7 and 7E from Wednesday, July 27 through Friday, July 29. (This closure is likely to be shorter.)

While the majority of the work for this project will only prompt single lane closures that will be managed with a signal, this intersection work will progress much more quickly and safely if a full closure is in place. Access for homes and businesses on 7E will be directed to the southern intersection of CO 7 & 7E.

ACC will have single-lane traffic at the culvert crossings managed by a temporary signal. These signals will alternate traffic during non-construction hours, with a maximum five-minute hold. During working hours, ACC will manage traffic using flaggers, who will keep the delays under 10 minutes. There will be exceptions for days when rockfall mitigation occurs, which may require holds up to 30 minutes.

ACC will be working from 7 a.m. - 7 p.m., Monday through Friday, with work in the roadway complete by noon on Friday.

Phase I of upper CO 7 is scheduled for July 2016 – October 2017, with a winter work stop from mid-November to mid-March. A work stop means no construction will occur and there will be no traffic control related to this project within the roadway.

Traffic Impacts

• Full closure of the northern intersection of CO 7 & 7E from July 27 – July 29. Access is available at the southern intersection.
• Culvert work along CO 7 will prompt single lane closures at the point of work with through traffic alternating at the direction of a signal. Holds will be fewer than 5 minutes.
• Limited flagger-manned traffic holds may occur as equipment mobilizes in/out of a work site, and longer delays may be required if scaling for rock excavation is needed. These holds will be approximately 20 minutes long.
