HONOLULU – The Hawaii Department of Transportation (HDOT) advises Oahu motorists that the westbound H-1 Freeway will be closed at night in the vicinity of the Radford Drive Overpass and the Kapolei Interchange. See closure details below.

Radford Drive Overpass: Monday, March 20, 2017

• Three lanes will be closed (one lane open) in the westbound direction from 9 p.m. to 1 a.m.
• Westbound H-1 Freeway will be closed from 1 a.m. to 4 a.m. (if needed)
• Nimitz Highway On-Ramp to the westbound H-1 Freeway will be closed from 1 a.m. to 4 a.m.
• Single left lane will be closed in the eastbound direction from 7 p.m. to 4 a.m.

Motorists traveling on the westbound H-1 Freeway will be directed to Kamehameha Highway as the alternate route. If possible, motorists are encouraged to stay on the Moanalua Freeway to bypass the airport viaduct and the work area.

A full closure is necessary to remove the existing variable message board sign at the Radford Drive Overpass. A crane and large vehicles are necessary to lift the sign and place it on a truck to haul away.

Daytime closures:

The project will also require daytime closures on the eastbound H-1 Freeway beginning Monday, March 20, 2017 through Friday, March 24, 2017 in the vicinity of the Radford Drive Overpass from 9 a.m. to 3:30 p.m.

Kapolei Interchange: Sunday night, March 19, 2017, through Friday morning, March 24, 2017

• Westbound H-1 Freeway will be closed between the Makakilo Drive Overpass and the Kalaeloa Boulevard Overpass from 10 p.m. to 5 a.m., nightly.

A full closure of the H-1 Freeway is necessary to install a temporary working platform along the edge of the Farrington Highway Overpass bridge for the retrofit part of the Kapolei Interchange Phase 2 project. The Makakilo Drive On-Ramp to the westbound H-1 Freeway will be closed during this time. Motorists traveling on the H-1 Freeway will be directed to Makakilo Drive from the Makakilo/Kapolei/Kalaeloa Off-Ramp (Exit 2) and may continue on Farrington Highway/Kamokila Boulevard, Wakea Street, and the Farrington Highway On-Ramp to return to the westbound H-1 Freeway. (See detour map below.)

HDOT advises motorists to prepare for the closures by checking traffic apps, mapping the best route, and adding extra travel time to their commutes.

Electronic message boards will be posted to warn motorists of the closures. Special Duty Police Officers will be on-site to assist with traffic control and safety procedures. Emergency vehicles, first responders and TheBus have been notified of the roadwork and will be allowed through on the H-1 Freeway at the Radford Drive Overpass but will not be allowed through at the Kapolei Interchange due to lifts placed on the freeway. Roadwork is weather permitting.
