Turnagain Pass Corridor Master Plan


This project will develop a corridor master plan for the Turnagain Pass area. The corridor surrounding the Seward Highway from approximately MP 56 to MP 75 is seen as having high potential to offer a wide-array of recreation opportunities and this planning effort could develop a long-term recreation vision and goals for the area, research and analyze various options, develop initial site designs, and conduct environmental reviews, working towards a comprehensive suite of shovel-ready projects that support public recreation of the area while respecting and enhancing the highway for the major transportation route that it is.

A master plan would create a long-term vision for Turnagain Pass, with modifications and capital improvements expected in the 20 years following the plan completion. In the process of developing a master plan, public involvement will be sought from current users, stakeholders, general public, and other interested parties. After the completion of the master plan, proposed improvements would be analyzed under the NEPA process including a possible Environmental Analysis and Decision Notice as applicable. Projects identified for the early phases of development may be brought to a conceptual design level (Design Narratives) to support quick implementation of high-priority plan elements.


  1. Develop and preserve a joint vision for the Turnagain Pass corridor
  2. Identify current needs, forecast future needs, and create a prioritized list of projects to address these needs.
  3. Increase long-term sustainability, safety, and access to forest lands for travelers and users


The study will develop a corridor master plan for the Turnagain Pass areas. The project team has structured the study around progressive deliverables in two phases that support stakeholder engagement at key milestones:

  1. Phase 1: Initial Conditions
    1. Develop an Engagement Plan for the entirety of the project
    2. Develop Existing Conditions
    3. Analyze travel demand in the corridor and identify project needs
    4. Prepare Phase 1 Report
  2. Phase 2: Corridor Investments
    1. Propose prioritized projects and improvements
    2. Develop conceptual designs and cost estimates
    3. Establish and management and maintenance strategy
    4. Conduct environmental analysis, as applicable
    5. Prepare a Final Report

The tasks for this study are organized around progressive memoranda leading to a final report. The research is guided by a project management team composed of FHWA Federal Lands Highway, US Forest Service, and the State of Alaska.

How to Engage

The study s anticipated timeline is 24 months total, ending in approximately December of 2024. The study team will engage Tribal governments, land management agencies, recreation users, and the public throughout to understand future needs.
