HONOLULU — Starting Sunday night, the Joint Base Pearl Harbor Hickham off-ramp (Exit 15) on the eastbound side of the H-1 Freeway will close to motorists, according to a Hawaii Department of Transportation news release.

The nightly closure will be effective 8 p.m. to 4 a.m. from Sunday through Friday. During the closure, crews will install overhead signage.

Motorists accessing Pearl Harbor will need to take the detour on the airport off-ramp (Exit 16), take the arrivals ramp to Aolele Street, turn left onto Nimitz Highway, then continue westbound to Pearl Harbor.

In addition, HDOT advises motorists to expect up to three lane closures on the H-1 Freeway in the westbound direction from Lagoon Drive to the Pearl Harbor Interchange, and in the eastbound direction from Salt Lake Boulevard to the Pearl Harbor Interchange.
