Dalton Highway MP 305 to 335 Reconstruction

Dalton 305 to 335 project area.

The Alaska Department of Transportation & Public Facilities (ADOT&PF), in cooperation with the Alaska Division of the Federal Highway Administration (FHWA), is proposing to reconstruct the Dalton Highway between milepost (MP) 305 and 335.

Project Purpose

  • Improve safety,
  • Reduce maintenance costs.

Project Scope

This project proposes to reconstruct the Dalton Highway between MP 305 and MP 335 including:

  • Re-grading and widening including rebuilding the road section to handle heavy traffic loads without seasonal load restrictions,
  • Improvements to deficient roadway geometry such as flattening curves and grades,
  • Replacing the Dan Creek Bridge near MP 331,
  • Constructing new turnouts,
  • Improving drainage through ditching, new culverts, and replacing existing culverts,
  • Reconstructing approaches,
  • Upgrading signing and delineators.

Construction is anticipated to begin in 2020.

Project Status and Schedule

The project team completed a tour of the project area in mid-September 2015. The project survey was completed in 2016, and geotechnical investigations are ongoing. The team is currently working on preliminary design work, geotechnical investigations, and environmental documentation.
