The San Ysidro Port of Entry is the world’s busiest land port of entry. San Ysidro is named for San Ysidro Labrador (Saint Isidore), The Patron Saint of farmers.
As of 2019, there are more than 17 million vehicles that cross the San Ysidro Port of Entry (with more than 45 million pedestrians).
The facility construction completed in the 1970s and upgraded in 2014 with a $577 million project to expand the lane and facilities. It moves Interface 5 further west, adds a new northbound inspection facility, and adds 1/3 more northbound lanes.
As of January 2020, this 3-phases project is complete. The project successfully gives more capacity to the screeners, more technology to the department of ICE. It also allows for a safer and cleaner southbound flow of traffic into Mexico. On the north-bound side, it is not faster, but it allows for a more secure process and ensures the safety of the agents and officers involved in protecting the United States from foreign terrorists.
