HONOLULU – The Hawaiʻi Department of Transportation (HDOT) informs highway users of a full closure of the Joint Base Pearl Harbor-Hickam (JBPHH) off-ramp (Exit 15B) from the westbound H-1 Freeway, for the Airport Viaduct Improvements Project. The ramp will be closed from 7 p.m., Friday, Aug. 2, continuously through 1 a.m., Monday, Aug. 5.

HDOT will utilize the full closure to survey the concrete deck, repair defective areas, allow for necessary curing time and install temporary striping in preparation for the planned surface treatment and concrete overlay.

During closure hours, motorists on the westbound H-1 Freeway will be detoured to the Arizona Memorial/Stadium off-ramp (Exit 15A), where they may make a left turn onto Center Drive and continue into JBPHH. See below for a map of the detour route.

Motorists traveling on Nimitz Highway will be detoured to Camp Catlin Drive, where they may make a left turn onto Arizona Road, a left turn onto Salt Lake Boulevard, and a right turn onto Radford Drive, where motorists may continue to Makalapa Gate, or take a left onto Valkenburgh St. to access the JBPHH Pass and ID office. See below for a map of the detour route.

Following the weekend of Aug. 2, work will continue with three lane closures on the westbound H-1 Freeway between the Ke‘ehi Interchange and Pearl Harbor Interchange on Friday nights through Monday mornings, from 7 p.m. to 4 a.m.

The Airport Viaduct Improvements Project completion is anticipated by May 2025, weather permitting.

HDOT reminds motorists to drive with caution, follow all traffic signs and to allow for extra travel time. To stay informed on future closures scheduled for the JBPHH off-ramp, please view our weekly roadwork list on the HDOT website at https://hidot.hawaii.gov/highways/roadwork/oahu/.
