Officials announced Wednesday that they had discovered a newly finished tunnel between San Diego and Tijuana, Mexico.
More than 100 tunnels typically used for drug smuggling and human trafficking have been discovered in California and Arizona since the 1990s. Some tunnels are super sophisticated with lighting, hydraulics and rail systems to transport millions of dollars worth of drugs across the border without detection.
