Kapaa’s Olohena Road to close Wednesday for retaining wall work

A portion of Olohena Road in Kapaa will close Wednesday from 9 a.m. to 1:30 p.m. so crews can pour a concrete retaining wall, a short window that will still disrupt a road many east-side residents use for daily travel, deliveries, errands and commutes. The County of Kauai said the work is being handled by the Department of Public Works and Earthworks Pacific.

The detour plan sends eastbound traffic on Olohena Road onto Waipouli Road from Kamalu Road via Olohena Road. Westbound traffic will be routed onto Waipouli Road via Hauiki Road and then onto Kamalu Road via Olohena Road. The county said motorists will need to use alternate routes during the work period and directed questions to Brandon Esaki of Earthworks Pacific. For drivers moving through Kapaa neighborhoods in the middle of the day, the closure will concentrate traffic onto the Waipouli, Kamalu and Hauiki road network.

The May 20 work is part of a longer effort along Olohena Road, also known as Route 581. County public works reports describe a larger improvements project between Kaapuni Road and Kāmalū Road that includes resurfacing and reconstruction where needed, paved shoulders where feasible and a new two-lane bridge over Konohiki Stream. In July 2025, the county said a new traffic pattern at Olohena and Kaapuni Road followed a unanimous Kauai County Council resolution in June 2025, with the goal of improving safety, visibility and traffic flow through a dedicated left-turn lane and a more conventional two-way stop.

This is not the first time the corridor has been disrupted by county construction. On March 11, 2024, the county closed a portion of Olohena Road from Kamalu Road to Waipouli Road for bridge replacement at Konohiki Stream, and local traffic was allowed through even though vehicles could not cross the bridge from either direction. In October 2025, the county announced lane closures near Kapaa Middle School for guardrail repair and installation, followed later in the year by a notice for roadway reconstruction and bridge work that said construction would be minimized during student pick-up and drop-off times.

Taken together, the notices show a corridor under repeated reconstruction as county crews work through one phase after another on a road that remains central to movement across Kapaa. The Wednesday closure is brief, but it lands on a route that has become a regular focus of county infrastructure work.
