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

Welcome

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


CURRENT STATUS

An Open House has been scheduled to provide public review and seek comments on the Draft Preliminary Engineering Report, including the engineer’s recommendation. 

PUBLIC OPEN HOUSE

When: June 27, 2018, stop by anytime between 4 and 6 p.m.
Where: Dimond Center Hotel, 700 E Dimond Blvd, Anchorage

The team’s evaluation of multiple interchange types is documented in the Draft Preliminary Engineering Report.  Two interchange types were selected for further consideration, a signalized tight diamond and a compressed diamond with roundabouts.  Both meet the forecasted capacity of the interchange, include access to local residents and businesses, and enhance non-motorized facilities. 

 

CommentsThe team requests your feedback by July 11, 2018 and will consider comments when making a final recommendation this summer.  Comments may be submitted via the project website, by email to Anne Brooks at: comments.brooksalaska@gmail.com or by phone to 907-272-1877.

  Please submit responses by Wednesday, July 11, 2018.

PROJECT DESCRIPTION

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.

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.
