The Hawaii Department of Transportation (HDOT) Airports Division is implementing a new system to identify gates and baggage claim areas at the Daniel K Inouye International Airport (HNL).

Starting 1 June this year, existing identification signs will be covered with placards with new gate and baggage claim identification numbers. Once the modernisation project is complete, the airport will replace them with new permanent signs.

The $23m sign replacement project is scheduled to be completed in 2019.

HDOT stated that the project is necessary to accommodate future expansion and additional gates and provide a better means of directing people through the airport property.

“The new signs will help the travelling public navigate the airport more effectively and is a precursor for future improvements.”

Under the project, nearly 3,100 signs inside and outside of the airport, along the roadways and within the terminals and parking structures will be upgraded.

Gate 6 is the last gate at the existing Diamond Head Concourse. Renaming the gates will accommodate the new concourse, which will add 15 to 20 additional gates.

The gates will also be changed from an alpha-numeric designation to their own distinct numbers.

Airlines Committee Hawaii co-chair Blaine Miyasato said: “The new signs will help the travelling public navigate the airport more effectively and is a precursor for future improvements while giving the airport a fresh new look.

“During the transition, airline and airport employees will direct passengers to their respective gates and baggage claim areas to ensure a smooth transition.”

Additionally, the Interisland Terminal will be known as Terminal 1 (Hawaiian Airlines) and Overseas Terminal as Terminal 2 (All Other Airlines) and Commuter Terminal as Terminal 3 (Mokulele Airlines).

Terminal 3 will be located on the Diamond Head side of the airport with passengers entering from Aolele Street between the United Cargo and Delta Cargo facilities.

New digital signs, which can add or delete information designed for efficient wayfinding, will be placed over the roadways to indicate people to the airline lobbies and check-in counters.
