Park County Chain-Up Stations

Project Complete!

The Colorado Department of Transportation, in collaboration with Zak Dirt, has completed the chain-up station project on Colorado Highway 9, north of Alma, and on US Highway 285 south of Grant. At both locations, shoulders were widened, erosion control measures were put in place, and electrical components were installed. The stations provide a safe location for freight and passenger vehicles to put chains on or off when the chain law is in effect, or during snow-packed driving conditions for traveling over Hoosier Pass (CO 9) or Kenosha Pass (US 285).

CORE electric is currently installing conduit along US 285 in order to provide power/service to the Grant chain up station. There will be intermittent shoulder closures until completion. Completion date is estimated to be mid-November.

Due to production delays, the installation and powering of control lighting centers at both locations will now take place in the summer of 2024. Despite these delays, truckers and other motorists will still be able to use the chain-up station without lighting and electronic signs this winter.


Project Benefits:

  • The project will allow motorists and freight vehicles a safe location to put chains on/off when the chain law is in effect, or in snow-packed driving conditions for traveling over Hoosier Pass (CO 9) or Kenosha Pass (US 285).
  • Advance warning signs will be installed to assist with wayfinding.
  • Lighting installation will improve visibility for motorists at chain up stations.
