120th Avenue Connection Final Phase

In September 2010, the Colorado Department of Transportation and the City and County of Broomfield completed the first two phases of the 120th Avenue Connection project. The initial phases of the project constructed a new six-lane portion of State Highway 128 and a bridge over US 36 that connects with Wadsworth Boulevard. Click here for a map of construction phasing. Prior to this project, motorists in the Broomfield area could only cross US 36 at Wadsworth Parkway. Now that the SH 128 bridge over US 36 is complete, motorists, pedestrians and bicyclists can access 120th Avenue by taking the new portion of SH 128. Click here for a map that shows how to access the new bridge from the local street network.

The final phase of the project will complete the construction of the new roadway that will connect SH 128 and 120th Avenue. It will also construct a grade separation at the Burlington Northern Santa Fe Railroad. A bird's eye view of what the project will look like when it is completed is pictured here.

Project Schedule

Currently, design and right of way acquisition are underway. Construction is anticipated to begin in 2014 with a duration of two years.

Project Budget

The project construction budget for the final phase is $26 million. 80% of the funding is federal with a 20% match from the City and County of Broomfield.
