San Diego International Airport has needed to replace its aging Terminal 1 for a long time now. In fact, the terminal is 53-years-old. With record numbers of passengers flying out of San Diego and Terminal 1 only offering 19 gates, the plan to replace the terminal should be a popular one.

Terminal 1 accounts for more than half of all traffic at the airport, and without any access to public transport, this causes traffic problems in nearby areas. One way in which the airport plans to alleviate traffic in the area is to provide a free shuttle bus service to and from the Old Town Transit Center.

The airport will also offer a new parking garage nearby, with capacity for 5,500 vehicles. Space will also be set aside for a future transportation station.

Public transportation aside, the upgrade of the terminal is huge news and will be a significant upgrade. The brand-new terminal will offer 1.2 million square feet of floor space with a split level area where arrivals and baggage claim will be on the lower level, and departures and security will be on the upper level. There will also be a new seating area where plenty of eating and shopping options will be available to travelers.

The terminal will have 30 gates, which is 11 more than what's currently available. To ease traffic on the airport's runway, a second taxiway will also be constructed. That's not all, the airport will also offer more security checkpoints with more lanes, and the building is set to be much more energy efficient.

The goal is to break ground on the new terminal sometime next year and open the first phase in 2024.
