H-1, Kamehameha Hwy. lane closures this weekend from Aiea-Pearl City

Local News

The state Department of Transportation advises Oahu motorists of multiple lane closures at various locations between Aiea and Pearl City scheduled between 8 p.m. Saturday, July 18, continuously through 4 a.m. Monday, July 20, for deck widening and concrete pours.

“Normally, on the weekends prior that we’ve done this work, all lanes have been open by 6 p.m. on Sunday evening, but this weekend the difference is that that lane is not going to be open at 6 p.m.,” said DOT spokesman Tim Sakahara. “We’re going to keep that one lane closed overnight, Sunday night until Monday morning at 4 a.m.”

The closures break down as follows:

  • 8 p.m. Saturday-10 a.m. Sunday: Three westbound right lanes closed between the Kaonohi Street Overpass and the Waipahu Off-Ramp (Exit 8B) for concrete pour.
  • 10 a.m.-2 p.m. Sunday: Two westbound right lanes closed for concrete curing.
  • 2 p.m. Sunday-4 a.m. Monday: One westbound right lane closed for concrete curing.

Motorists are advised not to exit the freeway and travel through Pearl City as a means to bypass the H-1 Freeway closures as there are lane closures in other locations.

There will be a full closure of the Moanalua Road On-Ramp to the westbound H-1 Freeway from 8 p.m. Saturday through 8 a.m. Sunday. Motorists can proceed westbound on Moanalua Road/Kuala Street and make a right turn at the Kamehameha Highway Intersection. The left lane accesses the westbound H-1 Freeway, and the right lane continues to the northbound H-2 Freeway.

Two westbound left lanes and one eastbound right lane will be closed on Kamehameha Highway between Puu Poni Street and Kuleana Road from 9 p.m. Saturday through 2 a.m. Sunday. Motorists are advised not to use Kamehameha Highway as a detour route to access the Kamehameha Highway On-Ramp to the westbound H-1 Freeway.

“The workers are going to be working above on the H-1 Freeway, but just as a safety precaution, they don’t want a lot of cars driving underneath on the highway below,” Sakahara said. “For those people that might be coming home from dinner or a bar or things like that might be stuck in that, so we want them to know that’s going on.”

During the concrete curing periods, the majority of crew personnel and equipment will vacate the work site, but lanes will remain closed as the concrete hardens. Motorists are asked to follow posted construction zone speed limits and drive slowly through the area to minimize negative vibration effects on the concrete as it hardens.

Westbound motorists are advised to plan ahead, adjust their travel times, and to expect delays. Motorists can use the GoAkamai website and mobile apps to see current traffic conditions and access images from over 200 traffic cameras on Oahu.
