Road Closures - Cyclists

Closure Due To Widespread Flood Recovery Efforts

James Canyon Road Closed - Local Residents, their invited guests and Services Only - No Outside Cars or Bicycles

Due to continued recovery and repair operations associated with the September 2013 flood event, Boulder County is re-establishing restrictions on non-local traffic, including bicycles, in James Canyon from the junction with Left Hand Canyon, through Jamestown, to the junction with State Highway 72 (Peak-to-Peak). The restrictions go into effect immediately. Lefthand Canyon will remain open to all roadway users.

Cycling Guidelines

  • If your primary mode of transportation is by bicycle and you live in an access restricted area, contact Carla Weinheimer with the Sheriff's Department located at 5600 Flatiron Parkway, or call 303-441-3650
  • On open roads be aware of possible debris on the side of the road (gravel, sand, branches) that has not been cleaned up.
  • Please adhere to road closures - these roads are closed because they are unsafe for travel.
