New Otay Mesa East Port of Entry crossing to finish in 2024 More than $500 million has been invested into the project to date, with a total of around $1 billion estimated for the facility on both sides of the border. Author: City News Service, Allison Royal (KFMB) Published: 8:52 AM PDT June 28, 2021 Updated: 5:38 PM PDT June 28, 2021 SAN DIEGO COUNTY, Calif. — Dignitaries from California and Mexico signed a memorandum of understanding Monday to open a new port of entry at the U.S-Mexico border in Otay Mesa by late 2024. Officials say the State Route 11/Otay Mesa East Port of Entry Project will help facilitate and bolster trade between the two countries by adding a third port of entry in the San Diego region, as well as cut down on motorist wait times at the border, thus improving air quality by reducing emissions from vehicles that are often idling bumper-to-bumper at border crossings.
