Honoapiilani Highway Realignment, Phase 1A

Project Description

Timely completion of the Honoapiilani Highway Realignment, Phase 1A project brought instant relief for the West Maui community and countless drivers. The bypass road provides a critical evacuation route during times of crisis and alleviates daily traffic congestion. In addition to the little over a mile of new roadway the project included two bridges one of which, the Kahoma Stream Bridge, won national recognition as the first of its kind in the United States.

To avoid the erosive forces of the stream’s irregular and strong water forces, and to protect recently discovered archaeological sites, a revolutionary inverted tied-arch bridge was designed and constructed completely avoiding any supports in the stream bed and banks while also eliminating any above grade structures normally required in an arch bridge design. To the credit of both the bridge’s designer and builder, the Kahoma Street Bridge received national recognition and awards and will long be an example of ingenuity and resourcefulness in engineering and construction circles.
