It’s been about 10 months since road crews first started digging up a nearly 4-mile stretch of the H-1 freeway through the heart of Honolulu for overdue repair and repaving work along the state’s busiest highway.

But by early Friday morning the overnight lane closures that have inconvenienced drivers and slowed late-night traffic should finally be in the rear view mirror, state traffic officials say.

The final lane closures for the state’s H-1 Rehabilitation Project were set to start at 8:30 p.m. Thursday and wrap up at 5 a.m. Friday, shutting down all the westbound lanes from the Vineyard Boulevard offramp to Halona Street, state Transportation Department spokesman Derek Inoshita said.

Also scheduled for overnight: eastbound lane closures along various segments of the H-1 up to the Vineyard onramp, but no closure that fully closes traffic heading in that direction, Inoshita added.

Work on the $45 million project to fix the H-1 roadway from Middle Street to Ward Avenue began in September. Some 200,000 vehicles use that 3.5-mile corridor through town each day. It was last paved about 15 years ago, transportation officials said.

In the coming months there could be "minimal" closures to do electrical inspections on the project, but nothing on the magnitude of the closures that have halted traffic in recent months, Inoshita said.
