Cross Florida Barge Canal in Putnam County

According to Wikipedia: "The Cross Florida Barge Canal, now officially the Marjorie Harris Carr Cross Florida Greenway is a protected green belt corridor, one mile wide in most places. It is named for the leader of opposition to the Cross Florida Barge Canal, a canal project to connect the Gulf of Mexico and the Atlantic Ocean across Florida for barge traffic. Two sections were built but the project was cancelled, mainly for environmental reasons."
