HONOLULU – The Hawaii Department of Transportation (HDOT) is pleased to announce the H-1 Freeway Pearl City Viaduct improvements project is nearing completion as all deck widening has been completed. Remaining construction activities includes opening the last 1,000 feet of new lane on the eastern end of the Pearl City Interchange, restriping lines to connect the additional full time travel lane from the Waimalu Offramp to the Pearl City Viaduct, overhead destination sign replacement and relocation, travel lane resurfacing, and the opening of the new shoulder lane for afternoon rush hour periods.

The line striping work to connect the existing 6th lane in Aiea to the new lane near the Waimalu Offramp and Pearl City Viaduct began Sunday night, Oct. 11. The work will be completed in approximately two weeks. On Oct. 13, the last of the concrete barriers were removed. The remaining portion of new lane is scheduled to open for use by the end of October, weather permitting. The new shoulder lane from the Aiea Heights Drive Overpass to the Waimalu Offramp will also open at the end of the month. The shoulder lane will be available for use from 3:30 – 6:00 pm, Monday through Friday, excluding holidays. More information will be provided as we approach the opening date.

In November crews will begin resurfacing the far right westbound travel lane of the Pearl City Viaduct to create a smooth roadway for motorists. Repaving work will replace one inch of the surface with a fast setting concrete overlay. The latex modified concrete mix is more durable and designed to protect and prevent damage to the structure. The work will be scheduled during the overnight hours and/or weekends to minimize traffic impacts.

Following the striping and paving work, crews will configure the overhead destination signs to align with the new lane configuration.

HDOT looks forward to the positive effect the improvements will have for commuters through the busiest corridor in the State.
