The two rightmost lanes on H-1 Freeway westbound between Nimitz Highway and the Pearl City/Waimalu offramp (Exit 10) will be closed from 9 p.m. to 4 a.m. nightly this week.

The ramps themselves will remain open during those hours, however.

The lane closures will allow the state Department of Transportation to conduct pavement striping.

Motorists are advised to use caution while driving through work areas and to allow for extra travel time. Roadwork is weather-permitting.
