One hell of a toll plaza, though!
Ships pay a toll for passage through the Panama Canal as follows. For example, based on charges updated on May 1, 2007 container ships pay a fee for passage through the Panama Canal based on capacity to carry shipping containers measuring twenty feet by eight feet by 8 and a half feet. For each twenty-foot equivalent unit (TEU) a ship pays $54. For a large container ship with a capacity of 4,400 TEU’s the toll to pass through the Panama Canal would be 4,400 X $54 = $237,600.
Smaller boats going through the Panama Canal are assessed a fee by length with boats less than fifty feet in length paying $500. Boats over 100 feet in length pay fees of $1,500 to pass through the Panama Canal.
