A Waterways Journal article describes the role of aids to navigation such as buoys and beacons on the Mississippi River and Tributaries system, and the Coast Guard's federal fleet of 50,000 ATONs. It is an overview of waterway safety infrastructure with no new event.
Reliable navigation aids support safe, efficient barge movement, but this piece describes no change in current supply or prices.
