How do swing bridge people know when a boat is going to come through?

As in... when a boat is coming, how does the swing bridge operator know - like does he get a text or what?

    Wow, Aaron, great question and excellent spelling and grammar. Most questions from young people are misspelled and bad wording as to the detail of the question.

    Most bridges that we go under and need opening we call on the radio to request an opening. Some times we call on the cell phone and if the bridge has little vessel traffic for openings sometimes we will call the day before or an hour or so before to let the bridge operator know we are in route. Not all vessels have radios and the bridge operator will open when requested by whistle signals too, normally 1 prolong blast followed by two short blast.

    Good Luck!

    Depends on the bridge. It can be visual, a horn signal or radio communication.
