At the foot of the Arthur Ravenel Bridge is Patriots Point, a naval and maritime museum, home to the World War II aircraft carrier USS Yorktown, which is now a museum ship. The Ravenel Bridge, an eight-lane highway that is part of U.S. Route 17 and was completed in 2005, spans the Cooper River and links Mount Pleasant with the city of Charleston.
