Officials say the new transportation hub will connect people directly from the airport to trains, buses, rental cars and will even have a place for bicycles.
"As the freeways have clogged more and more, the need for alternative transportation has expanded, so what's happened is what you're seeing here today, is really driven by need," said Dan Feger, executive director of the airport. "The need has said, you can't just get in your car and drive to the airport anymore."
It's the largest capital project in the airport's history, with a price tag of $112.6 million. Officials say construction will take two years to complete.
The transportation center will house rental car companies and a bus transit facility. It will be the only direct airport rail connection in Southern California, connecting passengers with Metrolink and Amtrak service.
"Airports have woken up to the fact that they're more than just a place to get on an airplane, and that they have impact that's region-wide," said Feger.
And officials say not only will it be more convenient for passengers, but it will also cut down on local traffic and improve air quality. The construction is expected to provide 600 jobs.
