More Project Location Maps

In April 2019, crews began modernizing 35 traffic signals on US 287, Colorado Highway 7 and CO 128 in Broomfield, Boulder and Jefferson counties.

Work includes:

  • removing and replacing outdated signal-controller cabinets and fiber optic cable;
  • installing new vehicle detectors, conflict monitors and closed circuit televisions; and
  • upgrading the communications at the intersection from serial to ethernet.

In addition to improving safety, the upgrades will help improve real-time traffic monitoring.

Phase 4 - March

Beginning March 2, 2020, the Colorado Department of Transportation (CDOT) and contract partner Interface Communications will begin modernizing traffic signals at 46 intersections along Interstate 70, US 40, US 6, CO 93, CO 72, CO 177, and CO 7.
As part of CDOT’s Whole System Whole Safety initiative, this project will improve safety by adding new traffic detection to improve realtime traffic monitoring.  Enhancements for the $2.35M project include:

  • Removing and replacing outdated signal controller cabinets and fiber optic cable.
    Installing new vehicle detectors, conflict monitors, closed circuit televisions.
    Upgrading the communications at the intersection from serial to ethernet.
