CO 9 Colorado River South Wildlife & Safety Improvements

Crews on this project are reconstructing an 11-mile segment of Colorado Highway (CO) 9 between Kremmling and Silverthorne. Project work, which will improve safety through the corridor, includes:

  • widening the shoulders to eight feet;
  • alignment upgrades;
  • installation of five wildlife underpasses and two overpasses

Work is expected to last through July 2017.


Progress

The Colorado River South Wildlife and Safety Improvements project has been shut down for the winter. Traffic configurations have returned to the original alignment.

Construction crews will complete the project in April 2017. The only remaining work involves landscape seeding.

All major structural work—including the construction of seven wildlife underpasses and overpasses— is complete.

Project Background

CO 9 is a major traffic route between Kremmling and Silverthorne in Summit and Grand counties. CDOT, Grand County, Colorado Parks and Wildlife, and the Blue Valley Ranch partnered on this project following numerous wildlife-vehicle collisions, and human fatalities, between mile posts 126 and 137. This narrow roadway, near the Green Mountain Dam Road and Colorado River Crossing, bisects feeding and watering habitat frequently used by wildlife.

In October 2013 the State Transportation Commission selected CO 9 for RAMP funding to fast track the safety-improvement project
