I-70 Kipling Interchange

The Environmental Assessment (EA) for the I-70/Kipling Interchange is available for public review through February 24, 2019. The EA provides a detailed evaluation of the Proposed Action Alternative (Diverging Diamond Interchange) in comparison with the No Action Alternative.

Public input will be considered by the Colorado Department of Transportation (CDOT) and the Federal Highway Administration (FHWA) prior to issuing a decision document to finalize the National Environmental Policy Act (NEPA) process.

Project Area

The focus of the project is the I-70/Kipling Street interchange area in Wheat Ridge.

The project study limits include:

  • I-70 from Ward Road to Wadsworth Boulevard
  • 44th Avenue to 51st Place on Kipling Street

Phase 1: Planning & Environmental Linkages Study

In July 2013, CDOT completed a Planning and Environmental Linkages (PEL) Study of the interchange. This detailed transportation study—informed by broad public outreach, including two public meetings, community focus groups and frequent agency coordination—provided a plan for future improvements to:

  • reduce congestion;
  • optimize operations;
  • improve safety; and
  • provide multimodal connections at the interchange.

Phase 2: NEPA & Preliminary Design

Starting in late 2016, the project team began the National Environmental Policy Act (NEPA) and Preliminary Design phase of work, which is required to move interchange improvements forward. This process is expected to be complete in early 2019.

This project will follow the CDOT and Federal Highway Administration (FHWA) NEPA process to:

  1. Examine the needs for improvements to the interchange area;
  2. Identify the proposed action;
  3. Investigate the anticipated benefits and impacts of the proposed improvements (through an environmental assessment);
  4. Produce preliminary design plans, and;
  5. Make funding, scheduling, and phasing recommendations.

Public and agency input will be used in the decision-making process.
