Beginning at 9 a.m. Monday, the H-1 Fwy. westbound on-ramp from Kalihi St. (Likelike Hwy.) will be closed daily except during morning rush-hours. It will be open only from 5 to 9 a.m. on weekdays. At all other hours it will be closed. This schedule will continue through Friday, July 25. If work is completed sooner, the lane closures will be reduced.

The H1 Freeway Rehab Project from the vicinity of Middle Street to the Vicinity of Ward Aveune is reconstructing one of the oldest sections of the H1 Freeway through the Honolulu corridor that averages up to 200,000 vehicles a day.

It will provide a durable, smooth riding surface, upgrade lighting and drainage, install median glare screens, and increase traffic capacity by adding a fourth lane in each direction through widening and restriping.

The Hawaii Department of Transportation is cautiously optimistic for substantial project completion by July 31.
