Left lane closures are possible in both directions all this week on Kahekili Highway from Kulukeoe Street to Ha'iku Road, the state Department of Transportation said.

The closures will occur from 8:30 a.m. to 3 p.m. as needed for median planter box construction.

The work is part of a $4.1 million project to landscape Kahekili Highway.

Motorists are advised to use caution while driving through the work areas and to allow extra travel time.
