Parks Highway – Cantwell to Healy Planning and Environmental Linkages (PEL) Study logo
Project No. NFHWY00492


The Alaska Department of Transportation and Public Facilities (DOT&PF) in partnership with the Federal Highway Administration (FHWA) Western Federal Lands (WFL) and the National Park Service (NPS), are working together to identify potential future transportation and access improvements along the Parks Highway corridor (mileposts [MP] 203 and 259) between Cantwell and Healy.

The study team is conducting a Planning and Environmental Linkages (PEL) study that will look at current and future conditions and needs of transportation and access facilities along the Parks Highway corridor as it relates to the users and communities in the areas between Cantwell and Healy.

Project Area


This PEL Study process will bring together regional, community, and local stakeholders for a comprehensive multi-modal look at recent, active, and future transportation improvements along the interstate highway corridor. Stakeholders, such as the DOT&PF, Denali National Park and Preserve, Denali Borough, Alaska Railroad, Native groups, local businesses, and the public will come together to identify current and future needs within the study area.

The study area corridor covers the mileposts between 203 and 259, beginning just north of Broad Pass and extending north to the turnoff for the community of Ferry, including the only road-accessible entrance to Denali National Park at MP 237. The area expects a 1-2% yearly increase in traffic and it currently experiences high volumes of commercial traffic (buses, vans, tractor trailers, and vehicles with boat trailers) as well as increased pedestrian and vehicle traffic during the primary tourist season (May to September).

This area is a focal point for visitors to the State of Alaska, the Denali area, and specifically for visitors to Denali National Park.

Study Purpose and Goals

The purpose of the study is to provide a framework for implementing future transportation improvements. A PEL Study moves our ideas from the planning process directly into the environmental review process.

Desired outcomes include:

  • A clear and actionable PEL Study that guides future transportation enhancements and development on the Parks Highway corridor.
  • A PEL process that brings together regional, community, and local stakeholders for a comprehensive multi-modal look at recent, active, and future improvements along this interstate highway corridor.

PEL Study goals include:

  • Collect, compile, and analyze information about the conditions and concerns along the corridor to support the identification of individual transportation projects.
  • Conduct field studies (archaeology, condition reports, maintenance concerns, public concerns) and compile data already collected (crash information, deficient curves, bridge conditions) that will focus the areas of greatest attention and anticipate future needs to address.
  • Develop and evaluate possible solutions to the concerns identified.
  • Identify projects, termini, costs, and range needed to effectively address concerns in a timely manner.


The PEL Study started in early 2020 and is expected to take approximately two years. The PEL process and study will be conducted in consultation with the public, stakeholders, and federal and state resource agencies and tribes. A public meeting will be held during each phase.

The three main phases of the study include:

  • Assessing needs and opportunities– complete!
  • Developing conceptual improvement options - underway
  • Preparing a PEL Study

The final PEL Study provides a framework for implementing future transportation improvements along the corridor.

Our project advisory committee (PAC) provides guidance and input throughout the study duration. The PAC consists of representatives from DOT&PF, FHWA, NPS, tribes, Denali Borough, local communities, other public agencies, trucking industry, railroad industry, tourism businesses, local businesses, non-motorized users, and environmental groups.

Project Status

The Study Team will provide public notice in advance of the second public meeting April 12 – May 12, 2021. The Draft PEL Study will be available for public comment and review in late 2021. Our team is committed to working with stakeholders to allow PEL data collection and findings to save time and resources in initiating infrastructure projects for the involved communities.
