Welcome to the Dowling Road/Seward Highway Interchange Reconstruction website.
The Alaska Department of Transportation and Public Facilities (DOT&PF) and design consultant, Lounsbury and Associates, is beginning preparation of the Design Study Report, Plans, Specifications and Estimates for the selected roundabout alternative. This work follows the recommendation developed in the Preliminary Engineering Report produced in 2018. The DSR will provide analysis of all elements of design and be coordinated with local entities, such as the Anchorage School District and Anchorage Metropolitan Area Transportation Solutions. In addition, the team will review and ensure compliance with existing plans, such as the Anchorage Bicycle and Pedestrian Plans. The results of their efforts will be presented at local forums and an early-summer public meeting.
As a reminder, the proposed work will include:
Construction for the proposed project is anticipated to begin in summer 2020.

Preliminary engineering, environmental, and design efforts will proceed on the schedule outlined below.
This project will reconstruct the Dowling Road/Seward Highway interchange. The goal is to improve safety, serve both motorized and non-motorized travelers, be cost-effective, and be easy to maintain. The reconstructed interchange will accommodate projected traffic through 2040.
This photo shows the existing Dowling Road and the transmission line (shown in red) adjacent to it. The yellow lines show existing DOT&PF right-of-way.
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.
