Work Begins On Improvements at C-470 & W. Quincy Ave

Villalobos Concrete, Inc. is proud to be the prime contractor for the upcoming traffic flow and ramp improvement project at the Colorado Highway 470 and W. Quincy Avenue intersection in Jefferson County. Beginning in mid-May, this state and federally funded project—led by the Colorado Department of Transportation—will include the construction of a single-lane roundabout with bypass lanes at the northbound C-470 ramp and a new T-intersection with a traffic signal at the southbound ramp. Work will take place Monday through Friday from 7 a.m. to 5 p.m., with some overnight and weekend operations as needed. The project is expected to be completed by late 2025.

Traffic Impacts

• Periodic on and off ramp closures to and from C-470 at Quincy Ave during off-peak daytime and overnight hours
• Some closures of half the existing Quincy Ave over C-470 bridge will be taken for roundabout and other construction
• A single lane closure on northbound C-470 will exist later in the project for sign work
• Onsite detour pavement will be built to route traffic around the proposed roundabout location
• Other detour routes will be marked for use during later phases of construction
• Signs and construction devices will be present to alert the public to the work zone, closures and restrictions
• Construction schedules are weather dependent and subject to change
