I've updated the status to "lost"/"removed but not replaced" (in database classification terms), since while the rest of it remains intact, what remains effectively functions as glorified piers on opposite sides.

A quick check of when exactly the bascule leaf was removed revealed that that was done on October 26, 2010.

The bridge is definitely out of service, cutting off Boot Key from Marathon Key.

This bridge no longer operates, but the bascule span is gone.

The Boot Key bridge has been permanently closed after the state declared it unsafe and decided it wasn't worth millions to render it safe.

Like so many open spaces in the Keys Boot Key was originally slated for development, thus the apparent "platting" of streets. However to take a walk on the island (which I haven't done since the bridge closed) you find mangrove scrub land and dumped garbage along the road.

There is/was a radio station on the island 1600 am, as I recall and they had to commute by boat. Whether or not they've moved the radio station I haven't heard but the bridge is very much closed.

From what I been able to uncover is that the State of Florida found the bridge to be deficient during an inspection back in 2007. The City of Marathon which owned the bridge immediately closed it.

The city figured it would be easier and cheaper to buy out any property owners that where upset by the cutoff of access than to actually make repairs to the bridge. Most took the money offered but one decided to file a lawsuit. That owner had a radio antenna on the south west, a notable square section.


After two years there was a settlement.


The bascule span that was previously locked in the upright position was soon removed. The now inaccessible properties on Boot Key bought out by the city are being transferred to a type of nature conservatory group.

Does anybody read these comments?

Very mysterious, both the bridge and Vaca Key. Here, and in Google Earth, there are "street views" of traffic crossing this bridge. But all aerial views suggest the draw span is missing. But that is not all.

It also appears that 931 is the only vehicular access to Vaca Key. And all aerial views show no traffic at all on the island.

Yet the island appears to have been platted with streets and utilities. But there are no buildings or cars on any of those streets.

What happened?
