Draft Environmental Assessment (EA)
Available December 29, 2025 to February 12, 2026.
This is the final opportunity to comment on the Environmental Review – more specifically the Draft Environmental Assessment (EA) and Draft Individual Section 4(f) Evaluation—of the Safer Seward Highway. Don’t worry, you’ll have more opportunities to engage and comment later on when design happens. Right now, we are focusing on environmental and human impacts of the proposed action.
The purpose of the project is to reduce crash rates and severity, improve mobility and reliability for all users, and safely accommodate mixed uses in the corridor. The proposed action is a divided four-lane highway with a separate pedestrian pathway. About 7 miles of the Alaska Railroad would be re-aligned to make space for the improvements. The modifications require the conversion of 281 acres within Chugach State Park and 17 acres within the Anchorage Coastal Wildlife Refuge to transportation use.
The Draft EA for the Safer Seward Highway project was released on December 29, 2025. This marks a critical milestone in the project’s environmental review process and is your final opportunity to provide input on the EA before it is finalized.
So… what’s happening?
- We’re conducting a series of public hearings in Girdwood, Anchorage and Indian in January 2026. Learn more about the January 2026 hearings.
- Comment Period for the Draft EA + Draft Individual Section 4(f) Evaluation
We invite all community members, corridor users, and stakeholders to review the document and submit comments from December 29, 2025 – February 12, 2026 (45 days).
What This Is and What It Isn’t
The EA evaluates potential environmental impacts of various alternatives and helps guide future decisions.
This EA is not a design document. It does not set the final design. We can also decide on no action – leaving the highway as is, and continuing to live with the safety problems that we have right now.
Why Your Voice Matters
Your feedback helps shape the future of the Seward Highway corridor. Really, it does because you drive it. Whether you live nearby, travel the route regularly, or care about Alaska’s transportation future — this is your chance to be heard. We want to hear it all: what you like and what you don’t like about the environmental assessment.
The Draft EA document is available digitally below. Hard copies are available at the Anchorage Loussac Library, 3rd Floor Public Notice area and at the Girdwood Library, Circulation Desk.
