Colorado Highway 159 resurfacing project to begin  between Ft. Garland and San Luis

June 28, 2019 - Southwestern Colorado

COSTILLA COUNTY — On July 8, the Colorado Department of Transportation will begin construction on Colorado Highway 159 in Costilla County. Construction efforts will consist of resurfacing CO 159 from Fort Garland to San Luis. 

Work will begin at the north end of CO 159 at MP 33.5 in Fort Garland, extending south toward San Luis to MP 18.5. In July, crews will begin the initial leveling course of the roadway and begin work on the railroad crossing south of 3rd Street in Fort Garland. After this work is complete, crews will begin overlay work. Milling at the north and south ends of the project is set to begin late summer 2019.


Project Location Map


Regular work hours are Monday to Friday from 6:30 am to 6:30 pm. No weekend work is anticipated. 

  • Single lane closures during resurfacing work.

  • During work on the Rio Grande Scenic Railroad crossing south of 3rd Street in Fort Garland, there will be a small detour for two days across the tracks. 

  • Motorists should expect minimal traffic impacts. 


The CO 159 resurfacing project includes surface treatment, leveling course to smooth the roadway, final overlay, shouldering, new signing and new pavement markings. The project will add an additional 10 years of life to the highway. Work will smooth the road surface and eliminate ruts and road damage, making the highway safer for the traveling public. Work is expected to end in Fall 2019, weather dependent.

A&S Construction Co. of Canon City, CO is the prime contractor on this $5 million project.

To heighten safety awareness, CDOT recently announced its Whole System — Whole Safety initiative. This project 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 interregional express service. Governor Polis has charged CDOT to further build on the state’s intermodal mobility options.
