MONTROSE & SAN MIGUEL COUNTIES The Colorado Department of Transportation and contractor Oldcastle SW Group, Inc., begin a project on Monday, March 30, 2020, that will greatly improve the driving surface and safety on Colorado Highway 141 through Slickrock and CO 145 near Redvale. 

Specifically, the CO 141 work zone lies between mile points (MP) 16.2 and 60.139. This stretch begins  approximately 35 miles south of the Montrose-San Miguel county line, continues through Slickrock and ends at Naturita in Montrose County. On CO 145, the work zone extends north and south of Redvale, in Montrose County, between MP 108.54 and 112.507. 

The work consists of full-depth reclamation (pulverizing the existing asphalt down to the dirt subgrade) followed by re-grading and application of new asphalt; a ‘mill and fill’ in some areas (removing the top several inches of asphalt and applying new); asphalt leveling over the majority of the project; and asphalt overlay of the entire two stretches. Safety improvements on both highways will also include shouldering work, guardrail replacement, center-line rumble strips and new pavement markings. 

The project was contracted to Oldcastle SW Group for $10.7 million.


Work will begin with full-depth reclamation on a three-mile section of CO 141, starting at MP 38.5 and progressing south to MP 35.5. Through the project’s completion in late November 2020, motorists can expect single-lane, alternating travel through the work zone(s) during daylight hours, Monday through Friday. Weekend work is not anticipated, though may be possible, if necessary to expedite the project’s completion.

Please avoid distractions as you travel through the work areas and go “Slow for the Cone Zone!”

In early 2019, CDOT announced its Whole System — Whole Safety initiative to heighten safety awareness. This initiative takes a systematic statewide approach to safety combining the benefits of CDOT’s programs that address driving behaviors, our built environment and the organization's operations. The goal is to improve the safety of Colorado’s transportation network by reducing the rate and severity of crashes and improving the safety of all transportation modes. The program has one simple mission—to get everyone home safely.


CDOT has approximately 3,000 employees located throughout Colorado, and manages more than 23,000 lane miles of highway and 3,429 bridges. CDOT also manages grant partnerships with a range of other agencies, including metropolitan planning organizations, local governments and airports. It also administers Bustang, the state-owned and operated inter-regional express service. Governor Jared Polis has charged CDOT to further build on the state’s multimodal mobility options.
