The state Department of Transportation is advising motorists of multiple lane closures scheduled between Aiea and Pearl City over the weekend for deck widening and concrete pours.

Three westbound right lanes on the H-1 will be closed between the Kaonohi Street Overpass and the Waipahu offramp Saturday night through Sunday.

The lanes will be closed from 8 p.m. to 10 a.m. Sunday and reduced again to one right lane from 2 p.m. to 4 a.m. Monday during the concrete curing process.

The department is advising motorists to stay on the freeway as there are other lane closures on Kamehameha Highway.

The Moanalua Road on-ramp to the H-1 westbound will be closed starting 8 p.m. Saturday through 8 a.m. Sunday. Motorists are advised to head westbound on Moanalua Road/Kuala Street and turn right at the Kamehameha Highway intersection to access the freeway.

Also, two westbound left lanes and one eastbound right lane on Kamehameha Highway between Puu Poni Street and Kuleana Road will be closed from 9 p.m. Saturday to 2 a.m. Sunday for concrete pours.

During the concrete curing periods, crew personnel and equipment will leave the work site, but lanes will remain closed as the concrete hardens. Drivers are asked to follow the posted speed limits and drive slowly through the area to minimize vibration effects on the concrete as it hardens.
