WASHINGTON (CNN) -- Authorities have found what they call the largest tunnel running into the United States along the U.S.-Mexican border. About 2 tons of marijuana were inside the tunnel, the Drug Enforcement Administration said, indicating that it appears to have been used to transport drugs. DEA and U.S. Immigration and Customs Enforcement agents discovered the tunnel Wednesday night. It runs from Tijuana, Mexico, to Otay Mesa, California. Officials said the tunnel is about seven-tenths of a mile (1,148 meters) or more than 1,200 yards long. Initial reports said it is 5 feet high and 3.5 feet wide.
