The Kapolei Interchange Complex project began in 2009 and has widened the shoulder lanes, created connecting on- and off-ramps, added an access roadway and made other improvements, according to the state Department of Transportation. The second phase of the project, which includes additional ramps and an overpass from the Wakea Street extension to westbound lanes of the H-1, is projected to be completed in 2019 and two more phases are planned to expand the Palailai Interchange and connect to a new state highway serving Kaleloa Harbor, according to the Kapolei Properties Division, which is part of the James Campbell Company LLC.
