Olowalu: The Road to Resilience
The University of Hawaii Manoa and The Nature Conservancy are completing a separate study to rethink, redesign, and restore the shoreline from Ukumehame to Launiupoko, including the existing Honoapi’ilani Highway. Learn more about Olowalu Project
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.
