Nearly $30 million worth of drugs were seized after federal authorities discovered a “sophisticated drug-smuggling tunnel” that connected an Otay Mesa warehouse to a warehouse in Tijuana earlier this month.
Federal officials said in a statement on Tuesday that the tunnel was discovered on March 19 as a result of an ongoing investigation by the San Diego Tunnel Task Force (SDTTF).
Agents believe the tunnel had existed for months because of its sophisticated features in some of its portions, such as an underground rail system, ventilation, lighting and reinforced walls. The tunnel had an average depth of 31 feet and is three feet wide throughout most of the passageway, officials said. It extends for more than 2,000 feet between the two warehouses.
