Project History

Background and Summary of Events (2011-2021)


  • HDOT assembled a community-based task force and began working on the Kamehameha Highway Realignment Project.
  • The task force held four well-attended community meetings. As the project was focused on protecting the highway from erosion, the "Most" Realignment Alternative, a proposed shift much farther mauka from the existing highway alignment, was evaluated.


  • HDOT installed temporary barriers along the edge of the right-of-way on the mauka side of Kamehameha Highway, prohibiting parking in the City and County's properties.


  • HDOT removed the barriers, as a result of a preliminary injunction that was issued by the First Circuit Court - the "Save Laniakea Beach" decision.


  • HDOT began preparation of a Draft Environmental Assessment that would allow for the reinstallation of the barriers.


  • HDOT, in working toward the Draft Environmental Assessment, applied for a Shoreline Certification with the State Department of Land and Natural Resources.
  • A Notice of Appeal was filed regarding this application.


  • The Notice of Appeal that was filed in 2017 was granted, requiring HDOT to reapply for the Shoreline Certification.
  • HDOT reapplied for a Shoreline Certification, but further community objections resulted in agency decisions that rejected HDOT's application.


  • A serious accident occurred in August 2019 in the vicinity of Laniakea Beach, reinforcing the need for change along this portion of Kamehameha Highway. HDOT revised the project so that it would be achievable within existing budget constraints and could be constructed in the near future.
  • This August 2019 accident resulted in shifting the primary purpose of the project from erosion protection for Kamehameha Highway to pedestrian safety and the project name changed from the 'Kamehameha Highway Realignment Project' to the 'Kamehameha Highway Pedestrian Safety Project'.


  • A court settlement in June 2020 provides for an interim solution for the Laniakea corridor by creating crosswalks and a one-way traffic pattern for the informal parking area. HDOT is not responsible for implementing this interim solution and no schedule has been provided to the community.


  • HDOT completed the Pre-Draft Environmental Assessment Scoping Phase, with a public comment period that ended on Friday, February 26, 2021.
  • HDOT published the Draft Environmental Assessment, with a comment period that closed on September 22, 2021.
  • HDOT published the Final Environmental Assessment on December 23, 2021. This document had a "Finding of No Significant Impact" determination.
