The phased closure of southbound lanes on Interstate 5 is causing growing concern for thousands of drivers who cross daily from San Diego into Tijuana. Since the night of January 6, lane reductions near the San Ysidro Port of Entry have led to shifting traffic patterns and unpredictable wait times for motorists heading into Mexico.
How Drivers Can Track Border Traffic in Real Time
Because conditions can change quickly, commuters are being urged to monitor traffic in real time. Many rely on community Facebook groups focused on border traffic, where users regularly post live videos, photos, and firsthand updates. These reports often provide immediate insight into how long the line is, whether construction is causing temporary stoppages, and which lanes remain open, information that can be especially valuable when congestion builds unexpectedly.
Drivers can also check Caltrans’ interactive traffic map, which offers live camera feeds along the I-5 and I-805 corridors. The map uses color coding to show traffic flow and allows motorists to see where backups are forming, whether near the I-805 merge or closer to the border crossing itself. This can help drivers decide if using the Otay Mesa crossing may be a better option during heavy congestion.
Transportation officials recommend checking traffic conditions before leaving home and continuing to monitor them while on the road. Leaving extra time for work, school, or appointments is strongly advised, as is avoiding peak morning and afternoon commute hours when possible. Drivers are also urged to slow down and remain alert while traveling through construction zones.
Construction Timeline and What to Expect
The lane closures are part of a construction project taking place in two phases. Phase 1 began on January 6 and is scheduled to run through 5:00 a.m. on January 9. During this time, southbound lanes on both I-5 and I-805 are reduced as vehicles approach the border, creating bottlenecks and sudden slowdowns.
Phase 2 is set to begin at 5:00 a.m. on January 9 and could further impact traffic. This phase includes the continuous closure of the far-left southbound lane on I-5 near the San Ysidro Port of Entry. Officials warn the change could significantly increase wait times, particularly during peak hours and on weekends.
Authorities say they will continue to provide updates as construction moves forward and urge drivers to stay informed and plan ahead.
