Project Information: 

The main focus of the project is to pave the final 3 miles of the Owl Canyon corridor.  Along with the paving, the roadway will have minor vertical and horizontal geometric improvements that will allow for a posted speed limit of 50 mph once the project is complete.  The paved road will consist of one lane in each direction with 8 foot shoulders for a total paved width of 40 feet matching the previously reconstructed phases to the east of CR 21.  The current gravel road carries over 2,500 vehicles per day, including a large percentage of heavy trucks and recreational vehicles, which is more than 6 times above the paving threshold.  It is extremely challenging and expensive to maintain the existing gravel road with the existing traffic volumes and they are predicted to keep climbing.

CR 72 will be re-aligned at the US Highway 287 approach with this phase to straighten the two existing horizontal curves.  Re-striping of the existing dual northbound lanes on Hwy 287 at the CR 72 intersection is also proposed to allow for an exclusive northbound acceleration and deceleration lane on and off of Hwy 287. 

A new dual 12' wide by 4' tall concrete box culvert just west of Owl Canyon Trail will be constructed and drainage culverts will be replaced and upsized to properly convey stormwater flows under the roadway.  Fencing and gates will be replaced where impacted by the widening project.

A full road closure for the duration of the construction project is not anticipated with this phase.  Two lanes for local and through traffic will be maintained during construction.

The project will be funded entirely by Larimer County.  The preliminary construction cost estimate is $7.8 million.   

Project Status:

Design and construction plans are currently being prepared for the project.  Larimer County Engineering staff has held meetings with most of the adjacent property owners in recent months.  Additional right-of-way acquisitions needed for the widening are planned to occur during late 2020 and early 2021.  Construction is anticipated to begin in the Spring of 2021 and continue through the remainder of the year.
