On an average day, some 200,000 people cross the border north and south between Tijuana and San Diego, making the San Ysidro port of entry the busiest in the world -- and for commuters, a frustrating one. The wait to enter the U.S. regularly approaches three hours or more.
Now, as part of an ongoing multi-year expansion project at the port, the U.S. government is more than doubling the number of inspection booths, with the hope of cutting that wait down to 30 minutes tops.
