Slope protection work to close one lane on Hāna Highway

Posted on Jul 17, 2026 in Main, News

KAHULUI, Hawaiʻi – The Hawaiʻi Department of Transportation (HDOT) is notifying the public that the makai lane at mile marker 9.8 on Hāna Highway (Route 360) in Waikamoi will be closed for slope protection work.

The lane will be closed from 7 a.m. to 5 p.m. Mondays through Fridays, beginning Monday, July 20.

Traffic will be alternated in the open lane. Traffic controllers will assist motorists.

The closure is to allow for work necessitated by erosion caused by the Kona Low storms earlier this year. The project is expected to be completed in approximately three months.

Please follow all traffic controls and drive safely around the workers.

All work is weather permitting. For construction schedule updates or changes, see HDOT’s social media pages on https://www.facebook.com/HawaiiDepartmentOfTransportation and on Twitter/X @DOTHawaii.
