After months of delays, the historic SS United States ocean liner finally moved out of Philadelphia today on a new voyage as it prepares to become the world's largest artificial reef off the Florida coast in the Gulf of Mexico.

The SS United States is making its way past Florida on its final voyage. The historic ship left Philadelphia a week ago after sitting at its port for 30 years. You can track the ship's journey online.

Almost three decades later and with more than $40 million spent on rent, insurance, and feasibility studies, the SS United States — the dilapidated 990-foot ship that adorned or blemished the Delaware River waterfront, depending on whom you ask — has finally left Philadelphia.

The ship will now leave Philly on Wednesday, not Tuesday, to begin its journey of becoming the world's largest artificial reef.
