County Road 37 (Red Mountain Rd) Resurfacing Project


The Road and Bridge Department is working on a project to improve and surface CR 37 (Red Mountain Rd) in its entirety from the Colorado/Wyoming state line to US Highway 287. This section of road is currently a native surface and will receive a six-inch layer of aggregate base course. The project will include improvements to the roadside drainage, replacement of several drainage culverts, snow fence, minor width and horizontal alignment improvements along with the import and placement of approximately 50,000 tons of aggregate base course. 


Road and Bridge crews have continued to work on the resurfacing of CR 37 through the 2020/2021 winter.  Culvert installation is nearing completion, drainage and earthwork are approximately 2.5 miles from completion and the aggregate surfacing is approximately 3 miles from completion of the planned 9.7 miles.  Final completion is anticipated to be June of 2021.

County Road 44H (Buckhorn Road) Reconstruction Project


From the end of the asphalt west of County Road 27 to Ballard Road (Forest Road 129) the grade of County Road 44H will be raised to pre 2013 flood elevation.  The entire 10.13 mile length will be surfaced with a 6 inch depth of road base.  The road will remain on its present alignment and not impact Buckhorn Creek.  However, the first six culvert crossings of the Buckhorn Creek west of CR  27 will be replaced with concrete box culverts ranging in size from 25’x8’ to 15’x7’.  The existing 84” culvert approximately 0.4 east of Ballard Road will be extended a few feet on each end.

Construction Budget:  Approximately $7,300,000. 


Final approval for the project was given by FEMA in September 2020.  The project has been bid and awarded to Flatiron Constructors and work began on the project in early January 2021.  Work is underway on two of the seven crossings that are being improved.  The project is anticipated to be complete in the fall of 2021.

Red Feather Lakes Road Drainage Improvements


A 10-ft x 8-ft box culvert will be replaced using a tunnel liner system and a secondary steel pipe will be installed adjacent to it (which requires boring or pipe ramming the new pipe under the roadway).  The concrete box culvert is just east of the Lonepine Trailhead (at the curves with guardrail). The contract was awarded to Underground Infrastructure Technologies.. 

Project Budget:  $1,000,000


Construction has begun, starting with the construction of a temporary site access to both the upstream and downstream culvert openings. Additionally, the Contractor is preparing the platform necessary to begin the pipe-ramming operation. This work will continue for an estimated 3 weeks to install the 196-ft, 5-ft diameter steel pipe under live traffic. Continuous monitoring during pipe ramming is being done by Lithos Engineering. Underground Infrastructure Technologies LLC (UIT) has been awarded the work in the amount of $869,425.00.

Impacts to traffic during construction will be minimal except during times of equipment and material deliveries.
