Vasquez Boulevard Improvements: I-270 to 64th Avenue | Design Phase
About the Project
CDOT, in close coordination with Commerce City and Adams County, is conducting the Vasquez Boulevard I-270 to 64th Avenue project. This project aims to improve traffic operations, safety and pedestrian connections within the project area.
Vasquez Boulevard I-270 to 64th Avenue NEPA and Design project is located within the city limits of Commerce City in Adams County.
An Environmental Assessment study was conducted to identify potential impacts and mitigation strategies, per National Environmental Policy Act (NEPA) guidance. The study concluded in March 2024 with a Finding of No Significant Impact. The project will be designed and constructed in phases, with construction occurring on the first two funded construction packages from Spring 2025 through Fall 2027. Public and stakeholder coordination will continue to occur throughout the process. Coordination has been occurring with potentially impacted property owners to gather feedback related to refinements to minimize impacts as design progresses. Additional information can be found in the Resources links on the left side of this page.
Schedule & Important Dates
- Finalize design plans for construction package 1 (northeast area): Early 2025
- Begin construction for package 1: Spring 2025
- Finalize design plans for construction package 2 (remainder of improvements): Fall 2025
- Begin construction for package 2: Late 2025 / Early 2026
- Package 1 construction complete: Fall 2026
- Package 2 construction complete: Fall 2027
Planned improvements include the following main elements:
Construction Package 1 (construction beginning Spring 2025)
- 62nd Avenue/Vasquez Boulevard intersection: Intersection improvements with new traffic signal providing full access between Vasquez Boulevard/CO 2 and 62nd Avenue. Continuous-T intersection allows southbound Vasquez Boulevard through traffic to travel through intersection without stopping.
- 62nd Avenue between Vasquez Boulevard and Parkway Drive: Widening and addition of turn lanes.
- Parkway Drive/Forest Drive intersection: Add curb bulb-outs on the corners.
- 60th Avenue/Vasquez Boulevard/Parkway Drive intersection: Prohibit left turn from Parkway Drive (all inbound movements to Parkway Drive remain). Improve traffic signal phasing and timing. Add a new northbound right turn lane from Vasquez Boulevard to Parkway Drive and 60th Avenue.
- Vasquez Boulevard between 60th Avenue and 64th Avenue: Reconfigure lanes and striping.
Construction Package 2 (construction to begin Late 2025/Early 2026)
- Southwest quadrant of the 60th Avenue/Vasquez Boulevard intersection area: Add a new local roadway connection on the Clermont Street alignment running south-north from 60th Avenue to the 59th Avenue alignment, then turning to run east – west between Clermont Street and Dexter Street.
- Dexter Street/60th Avenue Intersection: Prohibit the northbound connection from Dexter Street to 60th Avenue (inbound movements from Vasquez Boulevard/60th Avenue to Dexter Street remain).
Construction Package 3 (on hold until funding is obtained)
- Northwest quadrant of the 60th Avenue/Vasquez Boulevard intersection area: Add a new local roadway connection running east – west between Dexter Street and Clermont Street on the 61st Avenue alignment. Add a left turn from Clermont Street onto 60th Avenue. The local road and sidewalk alignment and location of drainage ditches will be determined during final design.
- Dexter Street/60th Avenue intersection: Southbound Dexter Street traffic would have a right turn only at 60th Avenue.
- Extend the eastbound through/right turn lane for Vasquez Boulevard further west on 60th Avenue.
The Planning and Environmental Linkages (PEL) Study for Vasquez Boulevard was completed in August 2018 to provide a framework for the long-term implementation of transportation improvements along the Vasquez Boulevard corridor between 52nd Avenue and 64th Avenue as funding is available, and to be used as a resource for future project NEPA documentation. CDOT, in cooperation with FHWA and local agencies including Adams County, Commerce City, City and County of Denver, DRCOG and RTD, conducted the PEL study following FHWA and CDOT PEL guidance. The PEL study identified long-term transportation improvements and evaluated potential near-term projects that could be implemented with available funding.
Although the PEL study suggested some near-term projects in the vicinity of Vasquez Boulevard and 60th Avenue, additional work was needed to fully investigate a range of alternatives for improvements to be implemented with available funding. In 2020, the Vasquez Boulevard, I-270 to 64th NEPA and Design project developed and evaluated alternatives focused on addressing the project's Purpose and Need and goals, including consideration of alternatives carried forward from earlier study and newly developed alternatives. This process included extensive coordination with Commerce City and Adams County staff and elected officials, resulting in identification of the Proposed Project. The Proposed Project was then evaluated through the NEPA process, which concluded with a Finding of No Significant Impact in early 2024.
