The Alaska Department of Transportation and Public Facilities (DOT&PF), in cooperation with the Federal Highway Administration (FHWA), is proposing to rehabilitate the Glenn Highway from Airport Heights Drive to the Parks Highway Interchange. The purpose of the project is to extend the life of the pavement and provide safety and capacity improvements on entrance ramps that are found to be functionally deficient. Entrance ramps can cause congestion when traffic entering from the ramp doesn't have time to reach highway speeds and find appropriate gaps for merging. The entrance ramp geometry and lengths have been analyzed to determine locations where changes could be implemented to improve safety and decrease congestion.

In addition, the Glenn Highway Incident Management Traffic Accommodations project will construct median crossovers identified in the Glenn Highway Integrated Corridor Management (ICM) Study (2019) to reduce impacts from traffic incidents that often result in gridlock by rerouting traffic around an incident or to divert traffic around a construction work zone that require lane closures.

Improvements may include:

  • Resurfacing
  • Repairing the pavement structural section
  • Repairing or replacing culverts and other drainage improvements
  • Replacing damaged roadway signs, delineators, and lighting
  • Extending, repairing, or replacing guardrail
  • Reconstructing entrance ramps where recommended and as funding allows. Ramp reconstruction may include roadway lighting, drainage, signs, and guardrail improvements.
  • Constructing median crossovers

Status


The project got started in the fall of 2020. Crews have collected existing conditions data and completed an on-ramp traffic and safety analysis at nine interchanges in 2021. The Final Ramp Traffic and Safety Report (see Project Library) recommends improvements to upgrade 15 on-ramps to improve safety and traffic operations. Currently the design team are working on designs to upgrade on-ramps and fish passage culverts, replacing inadequate culverts and deteriorating pavement sections, and adding median crossovers identified in the Glenn Highway ICM Study. The project will be broken into phases to match available funding with the first phase anticipated to start construction in 2025.
