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.
Traffic Impacts: Week of Oct. 16
- Paving: One lane of alternating traffic with up to 45-minute delays
- Spring Creek Road and Blue Valley Acres residents: Plan extra time exiting your neighborhoods.
- Reduced speeds of 35 or 45 mph: Please exercise extreme caution
$40 million budget (RAMP)
- Average Annual Daily Traffic:
3,100 - 3,600
- Contractor(s): Kirkland Construction
The project is approximately 85 percent complete. Progress from phase 2 includes:
- 300,000 tons of earth moved
- 200,000 square yards of asphalt reclaimed
- 85,000 tons of asphalt laid
Construction crews are progressing ahead of schedule. Early project completion is weather dependent. The wildlife underpasses are 95 percent complete, with the overpass at 75 percent completion.
Crews are also installing the deer fence along the highway and completing slope grading throughout the project. Mainline paving operations are underway along the highway and expected to be completed by the end of September.
Schedule and Traffic Impacts
During daylight hours, Monday through Friday, crews will intermittently close northbound and southbound lanes from mile points 126-131 for paving. Please plan additional time for your commute as delays could reach 45 minutes.
Alternate routes are strongly advised. Motorists are encouraged to use US Highway 40 and CO Highway 131 to detour around construction. These routes will add 28-30 minutes to your trip.
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
