A cross-border drug tunnel measuring more than 300 meters was located inside a building in Tijuana, Baja California, that had access to San Diego, in the United States.
According to U.S. Customs and Border Protection (CBP), the tunnel was discovered by Border Patrol agents in San Diego in early April while it was under construction.
Upon entering, Tunnel Team agents identified the tunnel as having electrical wiring, lighting, ventilation systems, and a track system designed to transport large quantities of narcotics. Despite being incomplete, the Office detailed that it extended more than 300 meters into the United States and was “highly sophisticated.”
The first time agents entered the tunnel, they also found multiple makeshift barricades, which were placed haphazardly, presumably to impede progress into Mexico and prevent them from identifying the origin of the construction.
According to mapping conducted by U.S. authorities, the tunnel measured 888 meters long, 107 centimeters high, 71 centimeters wide, and extended nearly 15 meters underground at its deepest point.
