Southernmost point buoy

The City of Key West says it erected the Southernmost Point buoy in 1983 at the corner of South and Whitehead Streets, which the city describes as a mere 90 miles from Cuba, and calls it an anchored concrete buoy.

The city's page says a temporary buoy was established on 4 September 2025 at the southern end of Duval Street while seawall and roadway repairs are underway. Keys Weekly reported on 12 September 2025 that the original had been enclosed in a plywood box behind construction fencing and that an exact replica had been placed in the pedestrian plaza at the south end of Duval Street. Keys Weekly said the original would be unboxed, repainted and reopened when the work is finished, and that whether the temporary buoy stays is undecided. Keys News reported on 20 May 2026 that the project was still under way, the original was still encased, visitors were photographing the temporary buoy, and the city spokeswoman said there was no official word on when construction would be complete.
