Lane closures will be needed for secondary work beginning Sunday, Oct. 13; a full closure for expansion joint replacement will be scheduled later this month

HONOLULU – The Hawai‘i Department of Transportation (HDOT) informs freeway users that paving for the H-1 Freeway Resurfacing Project, Kapi‘olani Overpass to Miller Street has been completed. The regular full nightly closures of the H-1 westbound between University Avenue and Alexander Street will no longer be needed.

HDOT will close two left lanes on the H-1 westbound, from the University Avenue off-ramp to the Alexander Street on-ramp, on Sunday Oct. 13 through Monday morning, from 8:30 p.m. to 4:30 a.m. for adjustment of an electrical pull box in the freeway median and to clean spilled paint within the travel lanes.

Full nighttime closures will be needed for expansion joint replacement within the project limits. These closures will be announced when they are confirmed.

The estimated completion for the H-1 Freeway Resurfacing Project, Kapi‘olani Overpass to Miller Street was October 2024. HDOT appreciates the patience of road users as we work to maintain our highway system.
