Otay Mesa East Port of Entry Advances U.S.-Side Roadways as Caltrans and SANDAG Deploy Dynamic Tolling Tech

Civil Engineering Milestones on the U.S.-Mexico Border

SAN DIEGO, California — Construction on the U.S. side of the landmark Otay Mesa East (Otay II) Port of Entry reached pivotal engineering milestones on September 24–25, 2026, as Caltrans District 11 and the San Diego Association of Governments (SANDAG) advanced structural roadway overpasses and state-of-the-art commercial vehicle inspection approaches along the State Route 11 border corridor in South San Diego County.

The $1.1 billion binational infrastructure project is engineered to provide a 21st-century border crossing that dramatically reduces international freight delays between Tijuana, Baja California, and Southern California logistics corridors. Project directors confirmed that civil grading and highway interchange connectors are proceeding toward an anticipated facility commissioning in late 2028.

Automated Smart Tolling and Real-Time Wait-Time Modeling

A defining innovation of the Otay Mesa East facility is its binational, all-electronic dynamic tolling system, currently undergoing advanced field testing. Transportation engineers are integrating sophisticated algorithms and optical vehicle recognition sensors that automatically adjust toll rates based on real-time border traffic density.

The dynamic system is engineered to guarantee commercial cargo carriers and passenger motorists an average border wait time of 20 minutes or less, utilizing variable tolling to balance traffic flows between the existing Otay Mesa, Tecate, and San Ysidro ports of entry.

Unlocking Billions in Cross-Border Trade and Emission Reductions

Regional commerce leaders and clean air regulators underscored the profound economic and environmental impacts of the new port of entry. Prolonged diesel truck idling at existing border crossings currently causes substantial localized air emissions and costs cross-border supply chains hundreds of millions annually. By streamlining freight processing, Otay Mesa East will inject an estimated $1.8 billion annually into regional manufacturing while significantly slashing greenhouse gas emissions across South Bay border communities.
