HONOLULU (HawaiiNewsNow) - Heads up for Oahu motorists, crews will be closing the H-1 freeway tonight  in the westbound direction from the Vineyard Boulevard off-ramp to the Palama Street off-ramp.

The project was to be completed Tuesday morning; however weather delayed the project an extra day.

Crews are replacing an outdated electronic message board mounted on the Liliha Street overpass.

Work will begin with two left lane closures starting at 9 p.m., with the full closures beginning at 10:30 p.m.

During full closure hours, westbound traffic will be detoured to Vineyard Boulevard to re-enter the H-1 Freeway from the Halona Street On-Ramp. All eastbound lanes will remain open.

The following H-1 Freeway ramps will also be closed during the full closure hours

  • Punchbowl Street On-Ramp: Westbound motorists should use Vineyard Boulevard to the next available on-ramp at Halona Street. Kailua-bound motorists should use Vineyard Boulevard and turn right onto Pali Highway.
  • Pali Highway Off-Ramp (Exit 21B): Kailua-bound motorists should use Vineyard Boulevard and turn right onto Pali Highway northbound.
  • School Street Off-Ramp (Exit 21A): Motorists wishing to access North School Street should proceed west on Vineyard Boulevard, turn right onto Nuuanu Avenue and turn left to North School Street.
  • North School Street On-Ramp: Westbound motorists on School Street should continue west, turn left onto Liliha Street, turn right onto Vineyard Boulevard and proceed to the next available on-ramp at Halona Street.

Roadwork is weather permitting. This eastbound project should be completed by 4:30 Wednesday morning.

There will also be a full closure on the H-1 Freeway in the eastbound direction from Pearl City to Aiea. It was scheduled to start on Tuesday night, but has now been pushed back until Thursday.

Roads will close from 8 p.m. to 4 a.m.

DOT says the nightly roadwork is to replace an outdated electronic message-board mounted on the Kaamilo Street Overpass.

During construction hours, all eastbound traffic on the H-1 Freeway will be detoured onto Moanalua Road via the Pearlridge/Waimalu Off-Ramp (Exit 10).

The next available freeway on-ramp can be accessed from Moanalua Road via Aiea Access Road and from Kamehameha Highway east of McGrew Loop, both in the Aloha Stadium area.  All westbound H-1 freeway lanes will remain open.

Eastbound motorists on the H-1 Freeway coming from West Oahu can also use the Kamehameha Highway Off-Ramp (Exit 8A) as an alternate route through the Pearl City/Aiea area.

Motorists are advised to use caution when driving through these areas, to use alternate routes and allow for extra travel time.
