The lowest fixed bridge is 53 feet clearance

Actually not. The lowest is 49.38 ft, the railroad bridge just
east of Lake Okeechobee. There is a local service that will assist
with heeling taller masts over, up to about 55 feet or so. The
bridges at Cape Coral and Ft Myers are currently at about 54 ft
depending on the tide level.

Water levels are now good on the main route across the lake:

Wayne,

You are correct. In my haste I forgot about the RR bridge.

I deliver boats all around the state and make the cut about 10 times a
year when water levels allow
The bridge is actually 49'4" on the north side and 49'8" on the south
side. There is no tide but the water height varies a few inches.

You can stop at the Indiantown marina, east of the bridge, and have
your mast measured. Mine measured 48'9". If your mast and or bridge
won't make it, they will heal your boat until it will pass.

They secure 2*55 gal barrels on your deck and pump water into them to
heal your boat until you will clear, then tow you through the bridge
and remove the barrels. I believe the cost is $150.

They are set up do this without fuss and are efficient. It's also a
good place to stop for fuel, etc. You can radio them and they will
tell you the height of the water.

They can also remove a mast if required. I don't know whether they can
step it or not.
