Having trouble viewing this email? View it as a Web page.
I wanted to make sure you saw CDOT's updated days and times for closing CO 119 next week:
Full Canyon Closures Monday through Thursday, No Work Friday
Monday, May 20 through Thursday, May 24, State Highway 119 - Boulder Canyon will have single and full lane closures. During working hours there will be up to 5 areas impacted concurrently.
Full Highway Closures
Monday through Thursday (May 20 through May 23) rock blasting activities will result in a full closure of CO119 from MP 39-40, between the hours of 10 a.m. to 2 p.m. Motorists entering the canyon from Nederland will be stopped at 9:45am.
The new closure time between the hours of 10 a.m. to 2 p.m. will allow increased time for bigger blasts of rock which will eliminate the overall number of closures needed to complete the work.
Concrete Barrier removals are planned Monday through Thursday from MP 32-33.
Embankment installation will be done Monday through Thursday from MP 38-39.
Asphalt paving, and pothole repairs continue, impacting MP 26-34, and culvert installation will impact MP 36-37. Motorist will be guided around the single lane closures with traffic control flaggers.
A single lane closure will remain in place near MP 39, 24-hrs a day, 7 days a week to preserve the work zone area. Traffic will be managed by a timed traffic signal.
Hours, Delay Times and Alternate Routes
Work hours for this week are Monday – Thursday, 7 a.m. to 5 p.m. Up to 35 minute delays are expected through the canyon during work hours. Speed limits are reduced to 25 miles per hour in the construction zones. The work is weather dependent and the schedule may change. Please plan additional time to travel through the construction zones or to use the alternate routes of CO-72 or Lefthand Canyon Drive, during the full road closure.
The Boulder Canyon Trail, from Boulder, at the canyon mouth to the Fourmile Canyon trailhead, will be closed Monday – Thursday, 5 a.m. to 2 p.m.
The Boulder Canyon Creek will be closed for recreational use from the Fourmile Canyon trailhead, to the canyon mouth in Boulder, Monday - Thursday, 10 a.m. – 2 p.m.
