U.S. authorities this week announced the discovery of the longest smuggling tunnel ever found on the Southwest border, stretching more than three-quarters of a mile from an industrial site in Tijuana, Mexico, to the San Diego area.

The tunnel featured an extensive rail cart system, forced air ventilation, high voltage electrical cables and panels, an elevator at the tunnel entrance and a drainage system.
