The SS United States, the former luxury ocean liner that was parked in South Philadelphia for almost 30 years, has reached Mobile, Ala., faster than expected and in one piece, proving the skeptics wrong.

After being docked in Philadelphia for nearly three decades, the SS United States -- once the world's fastest ocean liner -- has arrived in Mobile, Al., ahead of schedule to be prepared to be turned into an artificial reef.

The SS United States began its final approach into Mobile, Alabama, Monday morning, marking the end of the first leg of its journey to becoming the world's largest artificial reef.
