The Primeval Whirl roller coaster in Disney's Animal Kingdom is expected to remain closed until September. The ride, which was initially closed in January for refurbishment, has been the subject of a federal investigation following the death of a park mechanic in March of this year.
Russell Roscoe, 52, was struck while working on the ride March 13 and died after suffering massive head injuries. Since that time, the U.S. Occupational Safety and Health Administration has been conducting an investigation into the ride and the worker's death.
