US 36 Traffic Cameras
& CO 66 Fiber Optic Cable Newsletter

Work Moving Into the Town of Lyons

Project Update 

The Colorado Department of Transportation with contractor, Dillie and Kuhn, plan to start work in downtown Lyons toward the end of the week prior to Memorial Day weekend (subject to weather).

Potholing and boring operations will occur at the intersection of US Highway 36 and 5th Avenue. There will be a right-lane closure from 5th Avenue onto US 36 eastbound while construction is underway (see map below). 
This is in preparation for fiber optic cable installation, which is anticipated to begin later this summer.

Crews are also working their way along Colorado Highway 66 westbound from I-25 to Great Western Railroad Crossing (Mile Post 42.7 to MP 41.45) installing pull boxes. Shoulder closures are expected. 

Please visit http://COTrip.org for real-time impacts on this project and others across the state. Crews will be off the road by noon on Friday to accommodate for the heavy traffic associated with Memorial Day weekend.
 

About the Project

The project consists of bringing fiber optic cable to CO 66 and traffic cameras to US 36. Fiber optic cable will be installed from I-25 to Lyons offering support for the US 36 traffic cameras. Once it is completed, crews will move to US 36 with the introduction of traffic cameras. 

Benefits of fiber optic:
  • Expands internet access to communities
  • Offers support for traffic cameras
  • Manages traffic equipment and technologies
  • Improves emergency service communications

Benefits of traffic cameras: 
  • Helps to get first responders to the scene faster since they are monitored by CDOT Operation Centers 24 hours a day
  • Assists the public and snowplows in understanding road conditions before going out
  • Keeps an eye on a challenging canyon corridor, which has a history of flood, fire, heavy snow and strong winds
  • Assists authorities in managing traffic flow in real time
  • Encourages safer driving behavior with visible cameras
  • Collects data for future planning

Map shows the construction zone from I-25 to Estes Park on Colorado Highway 66 (fiber optic cable) and US Highway 36 (traffic cameras). Overall project begins at Mile Post 42.97 (CO 66) and continues west to MP 1.49 (US 36).
