Nighttime roadwork on Kūhiō Highway is scheduled to begin on January 4, 2026, between Oxford Street and Hardy Street and is expected to continue through mid-September. This work is part of the Kūhiō Highway (Hardy–Oxford) Waterline Project. During construction hours, the center two lanes will be closed, left-hand turns into side streets and businesses will be restricted, and traffic will be reduced to one northbound lane and one southbound lane to minimize impact on daytime traffic.
According to Kauai County, lane closures will occur on the following schedule: from midnight to 5 a.m. on January 4–5, then from 9 p.m. to 5 a.m. nightly from January 5–9, continuing nightly through September 15. The primary work zone will be located between Poinciana Street and Hardy Street until the end of January. Travelers on this route are advised to allow extra time or consider alternate routes.
The Waterline Project involves replacing aging infrastructure, including water mains, fire hydrants, and service connections to properties. The Department of Water aims to improve service reliability and prevent future failures. Work is expected to last approximately nine months. Residents may experience temporary water service interruptions, as well as noise, vibration, and dust during construction. Motorists are advised to follow posted signs and remain attentive to ensure safety.
