Is it possible to determine the raised vertical clearance of a bascule bridge from a chart? If not, how does one obtain this information? I understand that I can hail the operator but am an interested in knowing when I am planning the trip.
For example; reference the "Treasure Island Causeway Bascule Bridge" (St. Pete Beach, FL) on chart 11411 at 27.46N, 82.46W (approx).
The vertical clearance of the Treasure Island Causeway Bascule Bridge (St. Pete Beach, FL) depends on whether the two front wheels of a little old lady's Ford are hanging over it.
