Coast Pilot 4 calls it “the least overhead clearance of the fixed bridges over the main route of the Intracoastal Waterway between Norfolk and Miami”.

On Miami Beach Channel, away from the waterway route, Coast Pilot 4 gives the easterly fixed span of the same causeway a clearance of 35 feet.
Datum
Coast Pilot 4 chapter 12 does not restate a datum for this bridge clearance; chapter 1 gives cable clearances for the lowest wires at vertical datum, usually mean high water.
