County Road 70 (Owl Canyon Road) & County Road 9 Roadway Improvements

Project No. 339

(CR 70 (Owl Canyon Road) between CR 9 and CR 5 & CR 9 from CR 70 to the new Larimer County North Landfill


Last Updated: April, 2024


The project includes 1.5 miles of roadway widening and reconstruction of CR 70 from the CR 9 intersection to just west of I-25. The project also includes 4 miles of roadway widening of CR 9 from the CR 70 intersection to the new Larimer County North Landfill entrance. Both roadway widening projects will accommodate two lanes of roadway and 6- to 8-foot-wide paved shoulders. Bridges will be replaced at several irrigation canal crossings and major/minor drainage ways. Intersection improvements are planned for both the C9 and CR 7-5J intersections. Along with the roadway widening on CR 9, conduits for the County’s Broadband infrastructure extensions are being installed.  In addition to the above improvements CR 70 will also be repaved on the I-25 overpass and the gravel road section from I-25 to CR 5 will be paved to accommodate a 26’ paved roadway.


 Construction began on the project with the widening and resurfacing of CR 9 from just north of the CR 70/9 intersection up to the new Larimer County North Landfill site in August 2023, with the majority of the bridge and culvert replacement work around CR 70 continuing through the Fall and Winter. With most of the structure work starting to conclude, roadway widening and intersection work along CR 70 will continue to be ongoing throughout the rest of the Spring the thru the Summer. In mid-March, CR 70 had to be unexpectedly closed due to unforeseen poor conditions of the roadway as the road was being widened and reconstructed. The County will continue to do whatever it feasible can to keep the road open during construction as the project moves forward. The final road work associated with the project will be the replacement of the Boxelder Creek bridge located 0.3 miles north of the CR 70/9 intersection. The replacement of this bridge was delayed due to utility relocations needing to occur ahead of the bridge’s replacement. The project is expected to be substantially complete by the early October of 2024.

The project is funded through a combination of Larimer County Road and Bridge, Larimer County Solid Waste, Larimer County IT, and CDOT funds.
