WATCH: Drug-Smuggling 'Super Tunnel' Discovered

The discovery of a drug-smuggling super tunnel running 160 yards between Mexico and the US has left officials stunned.

The secret underground tunnel, equipped with electricity, ventilation and a rail system for smuggling drugs between a San Diego industrial park and Tijuana, Mexico, has now been shut down, US authorities said.

Border control and drug enforcement agents incredibly seized more than 17,000 pounds (7,700 kilograms) of marijuana and 325 pounds (147 kg) of cocaine from the tunnel.

US Attorney Laura Duffy described the latest passageway as a "super tunnel," saying it was equipped with an electronic rail system, hydraulic doors and a ventilation system.

The Sinaloa drug cartel is believed to have built and operated the tunnel, which ran 1,760 feet (536 meters) from Mexico to the United States.
