CO 9 Widening from Iron Springs to Frisco

Traffic Impacts

August 2020
    • Starting June 30, traffic on CO 9 will be realigned to a single lane temporary roundabout at the Intersection of Water Dance Drive and Peak One Blvd., replacing the traffic signal.
    • Daytime work hours range from 7 a.m. to 7 p.m. Monday through Friday.
    • Vehicles are reduced to a single lane in both directions for the duration of the 2020 construction season.
    • Motorists should expect flaggers on the roadway to help guide them through the construction zone or when work is near intersections and the recreation path.
    • The speed limit is reduced to 35 mph, and work zone fines are doubled. Motorists should plan for possible 15-minute traffic delays.

About the Project

In May 2020 crews will begin widening of CO 9 between MP 94.8 to 96.15 from Iron Springs to Frisco, Colorado, Summit County. The project will include:

  • Widening of CO 9 to four lanes
  • Installing noise walls along Water Dance and Frisco Bay Townhomes
  • Providing a pedestrian underpass between Peninsula Recreation Area and the County Commons
  • Building roundabouts at Water Dance Drive and 8th Avenue intersections
  • Rebuilding the CO 9 southbound free right turn lane onto Main Street
  • Replacing signals at Recreation Way and Main Street
  • Improving drainage throughout the corridor

This project is part of CDOT’s “Whole System. Whole Safety.” initiative aimed at enhancing safety for Colorado’s traveling public. The highway widening and intersection improvements will provide increased capacity, reduced travel times, as well as safer intersections and crossings for motorists and pedestrians.
