Lefthand Canyon construction update for Feb. 8, 2016

Hello Transportation Listserv Subscriber -

Even with the high volume of snow received last week, construction in Lefthand Canyon continues to move forward and remains on schedule. Work within the daily closure area consists predominantly of clearing materials and prepping areas for large-scale removal. The dirt and rock removed is either being used to create a new road base in this construction zone or is being stockpiled for future construction activities associated with the project. If you've traveled through the zone, you've noticed that most of the asphalt has been removed. This material is being ground up and reused as a new road base throughout this stretch of construction. A large goal of the project is to reuse whatever materials we can in order to minimize the need for outside materials that will need to be hauled into the area, and that includes trees and other vegetative material which can be used to help restore creek habitat.

Kelley Trucking is also currently working on the creek-side of the road to armor, strengthen and protect this area against future flood events. Subcontractors are working diligently on two new bridges, one of which is at the intersection of James Canyon and Lefthand Canyon drives. The other is just west of Olde Stage Road. The new bridges will greatly enhance the carrying capacity of water over the previous culverts.

Travel Impacts:

  • The road will continue to be closed from 8 a.m. to 4 p.m., Monday through Friday, between Olde Stage Road and James Canyon Drive
    • Work begins at 7 a.m. each day - The road is open for one pass in each direction at 7 a.m., 7:30 a.m. and 8 a.m. (Monday - Friday) before being fully closed.
    • Each weekday, the road opens at 4 p.m. and 4:30 p.m. for a single pass in each direction before being fully reopened at 5 p.m.
  • On Saturdays the road opens every 30 minutes between 7 a.m. and 5 p.m. for one pass in each direction between Olde Stage and James Canyon Drive
  • No work on Sundays

At the bridge project located near the intersection of James Canyon and Lefthand Canyon drives, flaggers will move travelers safely around the construction zone. Delays should hopefully be no longer than 3 to 5 minutes. The contractor believes they will be able to continue this pattern of traffic control for the foreseeable future. Any new information will be share via this email list and on

Boulder County, Central Federal Lands, and Kelley Trucking all thank you for your patience and understanding.

Please do not hesitate to contact me with questions, comments, or concerns.

Have a good day.
