The Hawaii Department of Transportation (DOT) has broken ground on a $750 million modernisation programme of Honolulu International airport, the state's largest.
The phased programme includes a new concourse for widebody aircraft, commuter terminal, cargo and maintenance facilities for Aloha Air Cargo and Hawaiian Airlines, taxiway widening and a consolidated rental car facility, according to the agency.
"Hawaii is the anchor of the Asia-Pacific region and the Honolulu International airport should reflect our reputation as a world class destination," says Hawaii governor Neil Abercrombie in a statement. "The revitalisation of our airports is necessary and represents a historic investment to address the growing demands from visitor, resident and business travellers in a manner worthy of the Aloha state."
The Mauka widebody concourse will have six widebody gates, or 11 narrowbody aircraft parking positions, and will be adjacent to the existing Interisland terminal. It is designed for up to Airbus A350-sized aircraft.
The new Diamond Head commuter terminal will have six gates and 14 aircraft positions. It is adjacent to the existing Diamond Head concourse.
The Aloha Air Cargo facility will be built first, with construction beginning on the Diamond Head terminal in the third quarter. Construction of the Mauka concourse will begin after the Diamond Head terminal is complete and the existing commuter facility is demolished.
The DOT broke ground on the project on 2 May.
