Roadway repair work will begin Tuesday, just as another big swell rolls in, on a section of Kamehameha Highway near Kaaawa damaged Saturday by high surf.

The state Department of Transportation said in a news release that the work is expected to wrap up within a week.

Crews will be at the site daily, 7 a.m. to 6 p.m., repairing the damaged asphalt and guardrail, filling the area with controlled low-strength material, installing new guardrail and repaving the road.

The makai lane of the two-lane highway near Kaaawa Valley Road and Kanenelu Beach in Kaaawa will remain closed 24 hours a day. Until repairs are finished, flag-wavers will assist with traffic contraflow in the mauka lane.

The DOT advises motorists to drive with caution.

Earlier this month, the state completed repairs to another surf damaged stretch of the highway just 100 feet north of of the current repair site.

DOT is continuing to work on long-term improvements to Kamehameha Highway along the shoreline in Kaaawa, Hauula and Punaluu, according to the news release. It will work with with federal, state and county partners to ensure the necessary steps for permitting are followed, and that development of the project includes community input.

For estimated travel times, DOT recommends traffic/mapping apps and websites, including GoAkamai.org.
