SAN DIEGO (CNS) - A cross-border gateway between San Diego and Tijuana's international airport opened Wednesday morning.

The enclosed 390-foot pedestrian skybridge spans the U.S./Mexico border and includes a full-service airline terminal on the U.S. side that can be used by ticketed passengers within 24 hours of a departing flight, or for arriving passengers, two hours after landing.

The rest of the privately run Cross Border Xpress terminal, known as CBX is accessible to members of the public who may be dropping off or picking up passengers. It's located at 2745 Otay Pacific Drive, between the San Ysidro and Otay Mesa border crossings.

"CBX will transform the border crossing experience for millions of travelers," said Carlos Laviada, an investor in the project and a frequent flyer.

"We started the planning and approvals for CBX over eight years ago, and it has garnered incredible support on both sides of the border," Laviada said. "Intercountry travel for leisure and business is a critical economic driver for this entire region."

CBX backers estimate that 2 million U.S. passengers fly out of Tijuana's airport annually.

Gen. Abelardo L. Rodriguez International Airport serves 34 cities in Mexico plus Shanghai and Tokyo.

"This will be a great new option for travel between the U.S. and Mexico," said Jerry Sanders, president and CEO of the San Diego Regional Chamber of Commerce. "It is unique in the world, and we expect the CBX will be a catalyst for economic growth in our region on both sides of the border."

Crossings are free through Dec. 18. Subsequent one-way fees will be $18 for adults, with 20 percent off for seniors 65 and up and youth ages 3-12. Children 2 and under are free.
