Airport Viaduct Deck Repair Project Map
Work has begun on the H-1 Freeway Airport Viaduct for approximately 94,000 square feet of concrete deck repairs. Weakened portions of the deck will be removed and replaced with a fast-setting concrete, and sealed with a concrete overlay. Roadwork also includes expansion joint repairs and pavement striping. The project, consisting primarily of weekend work, will preserve and prolong the life of the Airport Viaduct. Lanes under the Airport Viaduct on Nimitz Highway will be temporarily closed while deck demolition and reconstruction is happening above. For updated project information including lane closures, visit, and follow our Facebook and Twitter social media channels.

Vineyard Boulevard Resurfacing Project
Work has begun on the Vineyard Boulevard Resurfacing Project between Palama Street to the H-1 Freeway On-Ramp.  The project, which requires lane closures and primarily takes place between 8:30 – 3:30 p.m., will extend the life of the existing roadway, enhance driving safety and improve the surface condition of Vineyard Boulevard. Improvements will include reconstructing weakened pavement areas, replacing damaged curbs, gutters and sidewalks, installing new bus pads and loop detectors and replacing existing traffic signal heads with new, energy-efficient, LED optical units.
