History

Rio proper was platted as “Rio St. Lucie”, but the post office established on March 24, 1893, was called “Rio San Lucie”. On December 1, 1897, the post office name was shortened to “Rio”. The Rio post office was discontinued on March 15, 1902, with the area being taken over by the post office at Goslingville, which was located on the narrow peninsula just north of the present-day Roosevelt Bridge. On April 6, 1904, the Rio post office was reactivated and it continued until October 15, 1927, when it was added to the post office at Jensen, now known as Jensen Beach.
