CO 151 Resurfacing & Culvert Improvement in La Plata/Archuleta County

About the Project

The project will improve approximately 13 miles of CO 151 east of Ignacio (Mile Point 12.8) at the La Plata/Archuleta county line to south of the Old Coal Mine (MP 26). Work will include:

• Milling old asphalt
• Paving with new asphalt
• Shouldering
• Rumble strip installation
• Guardrail replacement
• Road sign replacement

Additional work will consist of six culvert improvements including repairing one culvert, cleaning out two culverts and replacing three culverts throughout the project limits.

Project Benefits

• The new asphalt will:
  • Add approximately 10 years of life to the highway
  • Provide a smoother road surface
  • Add durability by increasing the resistance of ruts and road damage
• The new 31-inch high guardrail:
  • Meets new safety standard requirements (former standard height of guardrail was 27 inches)
  • Help veering vehicles remain on the road more effectively
  • Make the highway safer for the traveling public

Work Schedule

• Monday through Friday from 7 a.m. to 7 p.m.
