Kealakaha Stream Bridge Replacement

Hawaiian Dredging proposed a very different approach to Hawaii DOT’s original plan for this bridge replacement across the 610 foot wide, 165 foot deep ravine where Kealakaha Stream flows.

The original plans called for two 180 foot long box girders connected by a 360 foot long curved segmental box structure.

Hawaiian Dredging went with the first time use in Hawaii of super girders from Washington State DOT and friction pendulum seismic isolation bearings. These “super girders” simplified the bridge deck construction.
