Current Status

The Alaska Department of Transportation and Public Facilities (DOT&PF) has assumed the responsibilities of the Federal Highway Administration under 23 U.S.C. 327 and is soliciting comments and information on a proposal to reconstruct the Dowling Road/Seward Highway interchange in Anchorage, Alaska.  The proposed work would include:

  • Reconstructing the existing Seward Highway bridge to facilitate the full width of the adjacent highway and center median.
  • Reconstructing the existing Dowling Road roundabouts and frontage roads
  • Minor horizontal and vertical realignments
  • Pedestrian and bicycle facility improvements
  • Upgrading curb ramps to comply with Americans with Disabilities Act (ADA) standards
  • Replacing or improving signage, striping, and lighting
  • Drainage improvements
  • Vegetation clearing
  • Utility relocations

This proposed project will comply with Section 106 of the National Historic Preservation Act; Executive Orders: 11990 (Wetlands Protection), 11988 (Floodplain Protection), 12898 (Environmental Justice), the Clean Air Act, Clean Water Act, Fish and Wildlife Coordination Act, and U.S. DOT Act Section 4(f).

Construction for the proposed project is anticipated to begin in summer 2020. To ensure that all possible factors are considered, please provide written comments to the following address by January 31, 2019.

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.
