120th Avenue Connection
Overview

The Colorado Department Of Transportation (CDOT), in partnership with the City and County of Broomfield, will extend 120th Avenue from Wadsworth Parkway, across US 36 to approximately 120th Avenue and Teller Street, including an intersection with US 287. The new 120th Avenue Connection will accommodate existing and forecasted east-west through-traffic, reduce out-of-direction travel, and alleviate traffic congestion.

The new 120th Avenue overpass is a 12-month Design-Build project, and the improvements will be completed in three phases:

Phase I (Design-Build) will construct portions of 120th Avenue (0.7 mile), a bridge carrying 120th Avenue over US 36, and a bridge carrying 120th Avenue over Commerce Street.

Phase II (Design-Bid-Build) will construct improvements to 120th Avenue east of US 36, and will require significant right-of-way acquisition and relocation. The project schedule has not been finalized.

Phase III will construct the local road system off of and around the 120th Avenue improvements constructed in Phase I. A portion of Phase III work is proposed to be included in Phase I work to maximize the "best value" of the design-build contract. The schedule for this phase will be announced in the future.
