Mexican authorities executed a search warrant on May 30 in the Nueva Tijuana neighborhood, uncovering a sophisticated tunnel connecting Tijuana, Mexico, to San Diego, USA [1]. U.S. agents seized $45 million worth of cocaine inside the tunnel, which was concealed beneath a fake discount store [2].
The tunnel stretches approximately 265 meters (870 feet) and lies about 6.3 meters (21 feet) underground [1]. It is equipped with lighting, ventilation, and an electronic transport system to facilitate rapid smuggling [1]. Authorities also recovered ammunition, suspected methamphetamine and marijuana, cell phones, and various documents at the site [1].
Mexican investigations indicate the tunnel likely connects to a street in San Diego; however, exact U.S. access points have not been confirmed [1]. The operation focused on violations of Mexico's firearms, explosives, and drug laws [1]. Officials described the discovery as a major blow to criminal groups using underground routes along the U.S.-Mexico border [1].
The seizure comes amid ongoing efforts to disrupt cross-border drug trafficking. The tunnel’s advanced infrastructure reflects increasing sophistication in smuggling networks operating in the region. Authorities continue to investigate the tunnel’s full extent and the identities of those responsible.
