HONOLULU — The state Department of Transportation advises O'ahu motorists that the H-1 Freeway ZipperLane will be deployed at 5 p.m. Sunday for overnight repaving work on the H-1 Freeway in the west-bound direction between Paiwa Street and Kunia Road in the Waikele/Waipahu area.

Crews will begin deploying the ZipperLane at 5 p.m. along the H-1 Airport Viaduct and are expected to reach the Waikele area shortly before 9 p.m.

The early deployment of the ZipperLane will separate crews from freeway traffic as part of a pavement-resurfacing project from Waipahu to Waikele and allow work crews adequate time to complete scheduled tasks. Construction hours will be between 9 p.m. to 4:30 a.m. The ZipperLane will then open to morning rush-hour traffic on the normal schedule at 5:30 a.m. Monday morning.

Nightly roadwork, with no early ZipperLane deployment, will resume on Monday night through Friday morning from 9 p.m. to 4:30 a.m.

This "pavement preservation" project will resurface all lanes along the 1.83 mile-stretch of the H-1 Freeway between Waipahu Street and the Waikele Stream Bridge and also includes the on- and-off-ramps at the Paiwa Interchange and the eastbound Waipahu off-ramp. Contractor Grace Pacific Corporation is scheduled to complete the $4.6 million project in June.

Pavement preservation projects help to extend the lifespan of roadway surfaces by repaving the top layer of asphalt before there is subsequent damage to the road foundation. This proactive approach prevents future repaving work that would be much more extensive and expensive, transportation officials said.
