Summary

County commissioners and staff told residents that widening State Highway 7 and grade-separating U.S. 85 at 120th Avenue depend on coordination with CDOT, railroads and funding from state and federal programs.

Adams County commissioners told a packed town-hall audience that work to widen State Highway 7 and build a grade-separated interchange at U.S. 85 and 120th Avenue depends on coordination with the Colorado Department of Transportation, regional partners and available funding.

Commissioners emphasized they participate on regional committees and coalitions to press for projects but said many roads within the county are owned and funded by state or federal agencies, which complicates timelines and responsibility. “It’s always a work in progress,” Commissioner Julie Duran Mullica said about coordinating county priorities with CDOT and other agencies.

Why it matters: Highway 7 and the 120th/85 corridor carry increasing traffic as new neighborhoods are built along those routes. County officials and residents said safety, congestion and bicycle/pedestrian access are immediate concerns.

County officials described the Highway 7 Coalition — a corridor group that includes municipalities from Brighton to Boulder — as a venue for joint planning and noted the railroad that crosses Highway 7 is a separate, often uncooperative, property owner that complicates station and crossing plans. Commissioner Lynn (last name not specified in the transcript) said the coalition “includes every entity along that entire corridor from Brighton to Boulder” and that design work for improvements has been completed in sections.

On the U.S. 85/120th Avenue interchange — a long-standing regional priority — commissioners said Adams County has committed $8 million toward design and right-of-way but that the full interchange remains unfunded and is not yet on CDOT’s 10-year program. “We recognize the urgency of this project,” a county public-works representative said, but added it will require state or federal funding to move into construction.

Officials encouraged residents to use the county’s online reporting tools and to weigh in at CDOT public meetings as a way to influence prioritization. Commissioners also said the county posts local projects on its website and plans to improve outreach and transparency about which projects the county controls and which are led by CDOT or cities.

Ending: County leaders said they will continue advocacy at the regional and state levels and asked residents to provide feedback and to participate in public comment periods for CDOT and regional planning efforts.
