Vasquez Blvd Improvements: I-270 to 64th Ave-NEPA and Design

About the Project

CDOT completed a Planning and Environmental Linkages (PEL) Study for Vasquez Boulevard between 52nd and 64th Avenues in 2018. That study identified long-term transportation improvements and evaluated potential near-term projects that could be implemented with available funding.

CDOT, in close coordination with Commerce City and Adams County, is now conducting the Vasquez Boulevard I-270 to 64th Avenue National Environmental Policy Act (NEPA) and Design project. This project aims to improve traffic operations and safety at and between the 60th Avenue, 62nd Avenue, and 64th Avenue intersections with Vasquez Boulevard.

Project Facts

  • Cost: TBD
  • Contractor: TBD
  • Timeline: August 2019 to 2023
  • Location: Commerce City in Adams County. 

CDOT conducted an alternatives development and evaluation process in 2020, considering alternatives carried forward from the PEL and newly developed alternatives. This process included extensive coordination with Commerce City and Adams County staff and elected officials. Preliminary recommendations have been made.

Coordination is currently occurring with potentially impacted property owners to gather feedback related to refinements to minimize impacts before preliminary design begins. This project will also include NEPA documentation and final design of the preferred alternative. The improvements are planned to be constructed starting in 2023, depending on funding availability. Public and stakeholder coordination will occur throughout the process. Additional information can be found through the Resources links on the left side of this page.


Vasquez Boulevard I-270 to 64th Avenue NEPA and Design project is located within the city limits of Commerce City in Adams County

The Vasquez Boulevard I-270 to 64th Avenue NEPA and Design project is located within the city limits of Commerce City in Adams County. The study limits include Vasquez Boulevard from 58th Avenue (just north of the I-270 interchange) to 66th Way, and is generally bounded between Clermont Street on the west and Glencoe Street on the east.

The Vasquez Boulevard I-270 to 64th Avenue NEPA and Design project began in August 2019 and is expected to be completed in Fall 2022.

Construction is anticipated to begin in late 2023, depending on the availability of funding.

  • NEPA Complete: Early 2022
  • Preliminary Design Complete: Early 2022
  • Final Design Complete: Summer 2022
  • Right-of-way Acquisition: 2022 to Summer 2023
  • Construction Begins: Late 2023

The PEL Study completed in 2018 carried forward three near-term intersection improvement concepts in this project area.

The next step following the PEL Study involved determining the Preferred Alternative. CDOT developed and evaluated alternatives focused on addressing the project’s Purpose and Need and goals. A draft Preferred Alternative has been identified.
