佛罗里达海峡
The shipping route between the east coast and gulf coast of the United States passes through the Straits of Florida, close to the Florida Reef that lies just off the Florida Keys. Prior to the 20th century many ships were wrecked around the southern end of the Florida peninsula. A railroad across the northern end of the Florida peninsula would allow cargoes from ships in the Gulf of Mexico to be transferred to ships in the Atlantic Ocean, and vice versa, without the risk of passage through the Straits of Florida, while cutting 800 miles off the trip.
