Bridges in Florida
Every bridge this guide has a figure for – the clearance its source publishes, the mile where it stands, and the words the number comes from.
Clearances are published at Mean High Water. Tide, wind, waves and lake level change what is really there.

“Below your air draft” means the published figure is lower than the number you entered. It never means a bridge is safe to pass – there is no green.
Lowest published clearance: 46 ft
