Project Updates

The Draft EIS publication is planned for release in Fall 2024. This will initiate a public comment process, followed by the Final EIS and Record of Decision planned for mid-2025.

Look forward to public meetings kicking off the Fall, in addition to the following project updates:

  • Environmental analyses are being reviewed by Hawaii Department of Transportation (HDOT) and the Federal Highway Administration (FHWA).
  • The Lahaina wildfire did not physically affect the highway project area, however it did result in delays and updated environmental analyses.
  • An extensive assessment of cultural resources is underway -HDOT and FHWA continue to consult with the State Historic Preservation Division (SHPD), local residents and cultural practitioners.
  • Evaluations of wetlands, waterways and threatened and endangered species continue.
  • The RAISE grant deadline for funding construction has been extended. 

Project Overview

The scenic coastal Honoapiʻilani Highway (State Route No. 30) is a single two-lane highway that currently serves as the primary access route to and from West Maui.

It is part of the island’s belt road system which operates as a two-lane principal arterial on the National Highway System (NHS) and Freight Network System (FNS).

The undivided highway provides two 12-foot travel lanes with 4-foot to 8-foot shoulders. Most of the highway terrain is relatively flat, lying close to mean sea level.

Project Purpose

The Primary Purpose of this project is to provide a reliable transportation facility in West Maui and improve Honoapiʻilani Highway’s resilience by reducing the highway’s vulnerability to coastal hazards.

Objectives:

  • Conform with Regional Land Use and Transportation Plans

Project Need

As a coastal highway, Honoapiʻilani Highway is vulnerable to:

  • sea level rise
  • passive flooding
  • annual high wave flooding
  • coastal erosion

As delineated by the Hawaii Climate Change Mitigation and Adaptation Commission (HCCC)’s Sea Level Rise Exposure Area (SLR-XA).
