US border authorities announced on Wednesday that they had discovered the longest-ever smuggling tunnel at the US-Mexico border, running a whopping 4,309 feet between Tijuana, Mexico, and San Diego.

US Customs and Border Protection said in a statement that Mexican authorities were the first to discover the tunnel’s entrance in Tijuana in late August.

Authorities have not made any arrests or drug seizures in connection with the tunnel, the statement said.

Photos and videos published by CBP revealed a sophisticated operation inside the tunnel, including a rail/cart system, ventilation, and electricity and drainage technology. Officials said the tunnel even had an elevator at the entrance.

Authorities said the entrance was concealed inside a “small industrial building” and extended north before bending slightly west.

The tunnel is more than 1,000 feet longer than the second-longest border tunnel, which was exposed in 2014 and extended 2,966 feet, CBP said.

The agency said the tunnel’s discovery was the result of a multiyear investigation involving several government agencies, including the Drug Enforcement Administration, Border Patrol, and Immigration and Customs Enforcement’s Homeland Security Investigations arm.

“I am thrilled that this high-level narco-tunnel has been discovered and will be rendered unusable for cross-border smuggling,” Aaron Heitke, a deputy chief patrol agent, said in the statement.
