CDOT upgrading signals in Northwest Metro Area

April 24, 2019 -


BROOMFIELD/BOULDER/JEFFERSON COUNTIES—CDOT has begun a project to enhance safety and functionality at 35 intersections along US Highway 287, and Colorado highways 7 and 128.

Upgrades include modernizing traffic signal communications, from Serial to Ethernet, replacing outdated controller cabinets and fiber optic cables, and the installation of new vehicle detectors, conflict monitors and closed circuit televisions.  These improvements will help reduce potential vehicle conflicts by improving real-time traffic monitoring, allowing CDOT to modify signal timing, improve traffic flow, cut vehicle emissions, and help reduce driver stress and frustration.

Drivers are urged to slow down to the posted speed limit through the various work zones, which will consist of single lane closures Sunday through Thursday from 9 p.m. to 5 a.m., and shoulder closures Monday through Friday from 6 a.m. to 6 p.m.
