There are 15 bridges in a 5 1/2 mile stretch in the Miami River, posing a major headache for waterway and roadway traffic. Greg and Susan Han bring us up to date on steps being taken to improve communication between bridge tenders and vessel operators.

As a local I am very familiar with the problems with the Miami area bridges. The problems seems to extend from Miami up to Palm beach. I am guessing that the operators in those counties work for various county and even cities and ar not as well trained or supervised.
See the article

from a working group on the Miami River of commercial operators who voices their concerns to the USCG.
While the commercial operators have different level of critical need, the problems they experienced are similar to ours. The Miami River Marine Group has taken a constructive approach ( after much private grousing I am sure) to communicate these concerns to the authorities and work to alleviate the problems. Perhaps some cruising association could organize their members and report problems and communicate with the authorities. Anyone know of an organization that could take this on?
