Baja California’s side of the Otay Mesa East port of entry is nearly complete. Drivers, truckers, and commuters cannot use it. The U.S. side of the crossing has not advanced far enough to create a functional link, and Mexican authorities have not authorized even partial operations. A proposal to open the Mexican infrastructure for limited cargo use was rejected this month, closing the last hope for any relief in 2026. The earliest realistic opening is now late 2027.
Two Decades of Planning Behind the Otay Mesa East Border Crossing
The idea for a third border crossing between Tijuana and San Diego dates back to the early 2000s. The San Diego Association of Governments, known as SANDAG, began environmental studies for a new port of entry east of the existing Otay Mesa crossing in 2003. California completed construction of State Route 11, the four-lane toll highway connecting the crossing site to the U.S. freeway system, in stages between 2012 and 2024. SR-11 runs about two miles from the existing Otay Mesa port to the planned new facility.
On the Mexican side, the project is called Mesa de Otay II. Baja California state officials oversaw construction of approach roads, inspection plazas, and associated infrastructure over the past several years. State officials now say the Mexican side is “practically finished.” But a border crossing requires two countries to be ready at the same time, and the U.S. port of entry buildings, inspection lanes, and customs technology are still under development.
SANDAG announced in April 2025 that a $150 million federal INFRA grant agreement had been finalized for the U.S. port of entry. The INFRA program, short for Infrastructure for Rebuilding America, funds large freight and highway projects. That grant represented a major funding milestone, but construction of the U.S. federal inspection facility is a separate process managed by the General Services Administration. SANDAG has described a phased opening plan targeting late 2027.
Current Otay Wait Times Average 100 Minutes for Cars
The delay matters in concrete terms. Border wait time data this month showed standard vehicle waits at the existing Otay Mesa crossing averaging about one hour and 40 minutes. During peak periods, waits can stretch well beyond two hours. SENTRI lane holders, who paid $122.25 and passed a background check for expedited crossing privileges, face shorter waits. But regular crossers absorb the full burden.
The San Ysidro port of entry, roughly 15 miles west, carries its own notorious congestion. CBP, the U.S. Customs and Border Protection agency, processes about 70,000 northbound vehicle passengers daily across all San Diego-area ports. San Ysidro alone handles approximately 50,000 of those crossings each day, making it the busiest land border crossing in the Western Hemisphere. Otay Mesa handles the rest, along with the bulk of commercial truck traffic.
Commercial trucks crossing at Otay Mesa carry goods tied to Baja California’s manufacturing sector. Tijuana’s industrial parks, concentrated in the Mesa de Otay area, house more than 600 maquiladoras producing aerospace components, medical devices, electronics, and auto parts. Each hour of border delay adds cost to every shipment. The American Trucking Association has estimated that border wait times cost the freight industry billions annually across all U.S.-Mexico crossings.
Cargo Workaround Proposal Rejected in April 2026
Industrial groups in Baja California pushed a proposal this month to use the completed Mexican infrastructure for limited cargo operations before the U.S. side opens. The logic was straightforward: if the buildings and roads are built, why not route some truck traffic through them to ease pressure at the existing crossing? The answer, according to officials, was also straightforward. Without a corresponding U.S. facility to receive and inspect the trucks, there is no way to process them. Mexican authorities declined to authorize even a partial opening.
That rejection eliminated any shortcut. No early cargo relief is coming in 2026, and the timeline remains fully dependent on U.S. construction progress.
Practical Realities for Regular Border Crossers
For anyone who crosses regularly at Otay Mesa, the situation will not change this year. Here is what to know:
- Current crossing options: Otay Mesa and San Ysidro remain the only vehicle crossings between Tijuana and San Diego. The Cross Border Xpress pedestrian bridge connects to the Tijuana airport but does not serve vehicle traffic.
- Wait times: Regular vehicle waits at Otay Mesa are averaging about 100 minutes as of April 2026. Check the CBP Border Wait Times page or the CBX app before heading to the line.
- SENTRI enrollment: Trusted traveler cards remain the single most effective way to reduce crossing time. Processing currently takes several months from application to interview.
- Otay Mesa East target date: SANDAG is planning a phased opening in late 2027. That timeline depends on U.S. federal construction staying on schedule.
- No partial opening: Do not plan around rumors of early operations. Mexican authorities have confirmed that no authorization for partial use has been granted.
Caltrans says the SR-11 highway connections on the U.S. side are complete, so the road to the new crossing exists. The crossing itself does not. SANDAG’s next public updates on the project timeline are expected in the second half of 2026. The original reporting on this story was published by a Baja California regional outlet.
