TUCSON, Ariz. -- The Tucson Sector Border Patrol discovered a drug tunnel Monday in Nogales, just six days after their earlier find of a smaller tunnel in the same town.
The tunnel is 319 feet long and extends 219 feet into the United States and 100 feet into Mexico, according to U.S. Customs and Border Protection. It is approximately 20 feet below the surace and measures 3 feet wide by 2 feet tall.
Authorities said the tunnel is more sophisticated than other recently discovered tunnels. It appears to have been chiseled through solid rock and was equipped with various digging tools, saws, electricity, lighting, water pumps, plywood shoring and 4x4 support beams.
While securing the tunnel, Nogales Border Patrol agents found 26 bundles of marijuana weighing more than 430 pounds and worth approximately $215,000. The narcotics were turned over to the Drug Enforcement Administration.
