Broadway, N.C. — A marijuana eradication effort in western Harnett County turned up an estimated $84 million in plants growing in a wooded area near Broadway, authorities said Wednesday.

With assistance from a state Highway Patrol helicopter, Harnett County deputies, State Bureau of Investigation agents and members of the North Carolina National Guard Drug Team located eight plots off Womack Road that contained a total of 35,000 marijuana plants, authorities said.

The plants were 1 to 4 feet high and were worth an estimated $84 million, authorities said.

No arrests had been made as of Tuesday morning, but authorities said investigators seized equipment to water and fertilize the plants and to protect them from animals and insects.
