Kapolei Interchange, Phase 2

Phase 2 provides an additional access point for motorists traveling into and out of Kapolei. The new Interchange provides motorists with an extended overpass of Wakea Street above the H-1 Freeway, connecting on- and off-ramps, and directional signage. With these improvements, westbound motorists have an alternate route into Kapolei via an off-ramp from the Westbound H-1 Freeway to Wakea Street, and an alternate route leaving Kapolei via the on-ramp to Westbound Farrington Highway from the Wakea Street extension. The construction of Phase 2 helps to relieve area congestion by providing additional ramps and a new overpass from the Wakea Street Extension to westbound lanes on H-1 Freeway.

Scope of work included the preparation of Plans & Specifications, Permanent BMP Report, Drainage Study, Geotechnical Investigation Reports, Engineer’s Preliminary Estimate, Utility Agreements, and Pavement Justification Report.  A noise variance was also prepared and processed. WOC also prepared a Transportation Management Plan.
