This Planning and Environmental Linkages (PEL) study is investigating the need and overall vision for improved access to I-70 between Horizon Drive and I-70B in Grand Junction.

An interchange at 29 Road has long been identified in many local and regional plans as a way to enhance local and regional connectivity, as part of a larger plan to provide connections in and around Grand Junction. Mesa County and the City of Grand Junction have been partnering on transportation improvements to support this connectivity for decades, including completion of Riverside Parkway and the project to carry 29 Road over I-70 Business Loop and the UPRR railroad. The city and county are continuing their partnership through this study to determine the best way to provide enhanced access to I-70 northeast of downtown Grand Junction.

The PEL Study has developed a thorough understanding of the existing and future transportation conditions and economic development opportunities within the project area. Throughout the study process, Mesa County and the City of Grand Junction are working closely with agency stakeholders, area stakeholders, and members of the public to identify issues and opportunities related to improving I-70 access at or between the Horizon Drive and I-70B interchanges.


Key elements of the study are to:

  • Identify the transportation vision and Purpose and Need for improved access to/from I-70 at or between Horizon Drive and I-70B. Complete the study in accordance with the Colorado Department of Transportation (CDOT) Planning and Environmental Linkages (PEL) process, including:
    • Public outreach
    • Direct involvement with local governments, community groups, and stakeholders within the interchange study area
    • Coordination with state and federal resource agencies
    • Documentation of study process, findings, and recommendations to National Environmental Policy Act (NEPA) standards, so information can be utilized or referenced in future NEPA documentation
    • PEL study documentation for FHWA concurrence
  • Identify existing and potential future transportation conditions and economic development opportunities within the study area.
  • Evaluate the potential benefits and impacts of additional interchange access along I-70.
  • Identify initial improvements that may be completed prior to construction of the full ultimate improvements.
  • Estimate conceptual cost of recommended transportation improvements.

PEL Process
This transportation study is being conducted using the PEL process. The PEL process is a study approach used to coordinate transportation planning efforts and to identify potential transportation benefits and impacts and environmental concerns, which can be applied to make planning decisions. PEL studies link planning efforts to future environmental processes and result in valuable information that may ultimately be used to prepare a NEPA study and project design.

PEL is a study process approach that is typically used to identify potential transportation benefits and impacts, along with environmental concerns, in a corridor or a specific location. It is generally conducted before overall project construction funding and phasing is identified, and before specific problems and solutions are known.

PEL studies can be used to make planning decisions and for planning analysis. These decisions and analyses, for example, can be used to identify and prioritize future projects, develop the Purpose and Need for a project, determine project size or length, and/or develop and refine a range of alternatives for improvements.

The PEL study process can be helpful in discovering needs and desires and garnering project support for an overall vision when a project involves multiple jurisdictions, and can be used as a prioritization tool.

PEL studies should be able to link planning efforts to environmental processes and result in useful information that can be carried forward into the National Environmental Policy Act (NEPA) process. The adoption and use of a PEL study in the NEPA process is subject to determination by the Colorado Department of Transportation (CDOT) and the Federal Highway Administration (FHWA).

The study area for this study includes I-70 between the existing adjacent Horizon Drive and I-70B interchanges and the north-south arterials of 29 Road, Horizon Drive, and I-70B from Patterson Road to I70.

The purpose of the project is to enhance the region’s transportation network to improve local and regional connectivity and to provide enhanced access to/from I-70 to planned land use.

Improved access to I-70 is needed to:

  • Address limited transportation network connectivity with no central north-south arterial corridor with access to/from I-70; and
  • Provide transportation infrastructure needed to support planned land use adjacent to and north of I-70.
  • A new interchange along I-70 between Horizon Drive and I-70B would provide a new direct connection between US 50 and the state’s major east-west route – I-70.
  • A new interchange would provide improved access to and from I-70 for residents and businesses to the south, potentially reducing trip lengths and traffic congestion on other routes.
  • A new interchange would create an opportunity to integrate development near the Grand Junction Regional Airport into the surrounding community.
  • It is envisioned a new interchange would spur new economic development in the Grand Valley, opening direct and convenient access to the commercial property north of I-70, as well as leading traffic to businesses along Patterson Road and North Avenue.

Understanding the ideas, perspectives, and needs of key stakeholders in the study area is critical to building broadly supported decisions and solutions. Multiple opportunities were provided for agency partners, area stakeholders, and the general public to engage and inform the study. The public and agency outreach included the following:

Public Engagement: The general public will be actively engaged to provide meaningful input on the area issues, project vision, evaluation of potential project benefits and impacts, and draft recommended improvements. In addition to an in-person and an online public meeting, presentations to groups and individual stakeholder meetings will occur as needed with those directly affected by the project. To request a presentation for your group, please contact Leah Langerman at leah.langerman@deainc.com.

Technical Team (TT): The TT met with consultant representatives to provide technical input throughout the study. The TT included staff from the local communities of Mesa County and City of Grand Junction, agencies including the Federal Highway Administration (FHWA), Colorado Department of Transportation (CDOT), Grand Valley Metropolitan Planning Organization (GVMPO), and Federal Aviation Administration (FAA), and Grand Junction Regional Airport. TT members kept their respective elected officials updated.

Presentations: Presentations occurred to keep policymakers and community members engaged throughout the study and to facilitate two-way information sharing. These presentations included the Mesa County Board of County Commissioners and Planning Commission, Grand Junction City Council and Planning Commission, Mesa County Regional Transportation Planning Organization, Grand Junction Regional Airport, and Independence Academy Charter School.

Public input is critical to making smart decisions for the 29 Road Interchange at I-70 PEL Study.  Submit your comments or questions here. All comments will be documented and used to help make project decisions.
