Station 3 - Schedule & Project Next Steps

Project Schedule

As design and construction continue, the project has seen a robust field season.

  • Geotechnical investigations are continuing at the bridge site
  • Extensive cultural resources research and monitoring have occurred throughout the project.
  • Site monitoring found cultural artifacts on June 7, 2021 (inadvertent discovery).
  • Water quality testing is continuing upon request.


The project has separated the western intersection of the new Sterling Highway and the existing Sterling Highway (MP 55 to 56) into its own phase – and it will now be Phase 5. This was previously a part of Phase 4.

Design and construction of the western intersection are contingent on the land exchange between Cook Inlet Region, Inc. (CIRI) and the U.S. Fish and Wildlife Service (USFWS), which is tentatively scheduled to happen this winter. Once the land exchange is complete, design of the intersection will begin.

Project completion will likely occur in 2027.


Coordination with property owners is well underway. Property appraisals are continuing on Phase 1B. The project is coordinating with Kenai Peninsula Borough & U.S. Forest Service to gain access to alignment on existing roadways. Phases 3-5 will not impact private property owners.

Station 4 - Watershed Connectivity

Hydrology Map

    Hydrological mapping is complete. Wetlands are maintained, and culverts, ditches, and wildlife passages will provide watershed connectivity throughout the project area.
