The two projects being celebrated include: 

  • US 160/CO 17 Intersection and Signal Improvements

    • Budget: $6.8 million

    • Funding Type: Surface Treatment and FASTER Safety Funds

    • Contractor: Concrete Works of Colorado, Inc.

    • Duration: July 2020 to March 2021

    • This project was located at the intersection of U.S. Hwy 160 and Colorado 17 on the east side of Alamosa. The enhancements will improve traffic flow through the intersection and provide improved safety and mobility for pedestrians and vehicles. The work included: 

      • full-depth reconstruction of the intersection 

      • deteriorating asphalt removed and upgraded with concrete pavement

      • new storm sewer system to improve drainage

      • new light signal to allow new traffic configuration

      • new cross walk features with universal push buttons and indicators for pedestrians

      • curb ramps in compliance with the Americans with Disabilities Act

  • CO 17 Widening and Resurfacing 

    • Budget: $30 million

    • Funding: Senate Bill 267, Surface Treatment, Rural Roads and System Engineering Analysis Funds

    • Contractor: APC Southern Construction Co. 

    • Duration: June 2020 to June 2021

    • This project was located on CO 17 from Hooper to the US 285 junction, MP 84.5 and 118.4. The construction greatly enhanced safety for travelers on the narrow two-lane roadway, with the widened shoulders providing a recovery area for vehicles veering off the road and safe location for vehicles to pull off of the highway during emergencies. The work consisted of:

      • widening the existing roadway

      • resurfacing overlay along 36 miles

      • culvert extensions and erosion control

      • Final signing, striping and rumble strips

The two projects amount to more than $36.8 million of asset and safety improvements in the San Luis Valley.
