Dowling Road Seward Highway Interchange Reconstruction
   State of Alaska Project Number CFHWY00359


Welcome to the Dowling Road/Seward Highway Interchange Reconstruction website. 

Current Status

The project is just getting underway. Thank you to all those who filled out the online survey about familiarity and use of different interchange types. The survey is now closed. If you would like to send a comment to the team please email Anne Brooks at or call toll free 866-535-1877. There will be a public open house later this year once the Draft Preliminary Engineering Report is available. To receive notice of the open house and other opportunities to participate, please sign up for email updates on the right side of this page.

Project Scope

The goal of the project is to provide a Dowling Road/Seward Highway interchange that serves both motorized and non-motorized travellers, is cost-effective, easy to maintain, and efficiently conveys both large and small vehicles. The reconstructed interchange will accommodate projected traffic volumes through 2040 and provide enhanced safety and mobility throughout the corridor.

This project will evaluate interchange types both with the existing bridge and with a replacement bridge.

Project History

Constructed in 2003, the existing roundabout interchange replaced two traffic signals with Alaska’s first multilane roundabouts and converted Dowling Road from a substandard two-lane road to five lanes. The roundabouts were designed to meet projected 2020 traffic volumes and the current traffic volumes at some of the approaches now exceed those projections, resulting in longer wait times. There were also right-of-way, utility, and other constraints that were limiting factors during the original design. The Alaska Department of Transportation and Public Facilities has since implemented safety fixes to solve some problems with the existing interchange and acquired additional right-of-way.
