WATCH: Secret Mexico/U.S. Tunnel Discovered – 3,000 Feet!

Split American and Mexican flags side by side.

In a stunning discovery, a federal agency has uncovered an almost 3,000-foot-long drug smuggling tunnel connecting Tijuana, Mexico, to a San Diego warehouse.

Watch the video below this post.

The San Diego Sector Border Patrol discovered the incomplete tunnel in early April. It extended over 1,000 feet into U.S. territory under the Otay Mesa Port of Entry.

This sophisticated passage featured electrical wiring, lighting, ventilation, and a rail system designed explicitly for transporting contraband across the border undetected.

At 2,918 feet long, the tunnel reached depths of 50 feet underground and measured 42 inches tall by 28 inches wide.

Workers had strategically placed makeshift barricades throughout the passageway, apparently to hinder Border Patrol agents’ progress and conceal the tunnel’s origin in Mexico.

The tunnel entrance was eventually traced to a Tijuana residence, where it had been cleverly concealed beneath freshly laid tile.

Mexican authorities assisted in locating this entry point, demonstrating that international cooperation remains essential despite the lax border policies.

Acting Chief Patrol Agent of the San Diego Sector Jeffrey D. Stalnaker said:

“As we continue to strengthen the nation’s air and maritime border security, it’s not surprising that foreign terrorist organizations would resort to underground routes. Disruption of narcotics smuggling tunnels is critical to protecting American lives. I’m grateful for the exceptional work of the Tunnel Team agents who placed themselves in danger, as well as the cooperation of our Mexican law enforcement partners.”

This discovery is just the tip of the iceberg. Since 1993, over 95 tunnels have been found and decommissioned in the San Diego area alone.

Border authorities confirmed that this tunnel will be filled with concrete to prevent its use by criminal organizations, including potential foreign terrorist organizations seeking to infiltrate the country.

The alarming increase in tunnel activity highlights the growing crisis at the southern border.

Since 1990, over 140 tunnels have been discovered breaching the U.S. border, with an 80% increase in such activity since 2008.

This surge directly coincides with periods of weakened border enforcement policies that effectively encourage cartels to expand their operations.

Texas is also being targeted. In January, a finished cross-border tunnel running from Juarez, Mexico, into storm drains was discovered in El Paso.

That tunnel was reportedly used for smuggling illegal aliens and sex-trafficking women.

Meanwhile, in 2020, the DEA found the longest tunnel ever discovered, stretching an astonishing 4,309 feet from Tijuana into American territory.

The House of Representatives has passed the Subterranean Border Defense Act to address tunnel activity.

Still, decisive executive action is desperately needed to restore order and security to the southern border.
