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:

  • Provide Regional Transportation System Linkages that Support the Safe Movement of People and Goods
  • Conform with Regional Land Use and Transportation Plans

  • 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).
