San Diego International Airport in the US is proceeding with the construction of a long-anticipated parking plaza by Terminal 2, following a vote by the board of the San Diego County Regional Airport Authority.

Estimated to take three years to plan and build, the latest project will feature a three-storey parking structure with 3,000 spaces.

Airport Authority president and CEO Thella F Bowens said: "Our need for more close-in parking is clear."

"Our single lowest customer satisfaction rating is for parking availability."

"Our single lowest customer satisfaction rating is for parking availability. Building this plaza will enhance customer service, especially for the business traveller for whom convenient, close-in parking is a priority."

The airport’s smart-parking technology will allow parkers to reserve spaces and pay before leaving, resulting in reduced circulating and idling times.

The board originally approved the project in 2008, but the parking structure was deferred when the rest of the airport master plan started.
