HONOLULU (KHON2) — The Hawaiʻi Department of Transportation is closing the westbound H-1 Freeway Airport Viaduct for nighttime construction on Friday, May 16, and Saturday, May 17.
The full closure begins at 11 p.m. and ends at 6 a.m. each day. It’s all part of the ongoing improvement project for the viaduct.
Here is what you need to know.
Know where the closure starts and ends
The entire westbound section of the H-1 Airport Viaduct will close between the Keehi Interchange and the Pearl Harbor Interchange. During the closure, no westbound traffic will be allowed on that stretch of freeway.
Plan ahead for detours
On-ramps to the viaduct from Lunalilo Freeway, Nimitz Highway and Kamehameha Highway will also be closed. Drivers should use Nimitz Highway as a detour.
The Rodgers Boulevard on-ramp from Daniel K. Inouye International Airport will remain open, but the Aolele Street on-ramp will be closed from 11 p.m. Friday until 1 a.m. Saturday.
Expect more weekend lane closures
Even outside of the full closures, three right lanes on the westbound viaduct remain closed on weekends. This ongoing lane restriction will continue until mid-June, so plan accordingly if you travel that route.
Construction crews will be installing expansion joints
This part of the project involves working on the concrete deck and placing expansion joints across the road surface. This work is necessary to support the long-term structure of the freeway.
Always follow safety signs and updates
HDOT urges all drivers to obey traffic signs and barriers. Special duty police officers will be on site.
