One-way traffic lanes are RECOMMENDED for use by all vessels traveling between the points involved. 
They have been designed to aid in the prevention of collisions at the  approaches to Boston Harbor 
and New York Harbor, but are not intended in any way to supersede or alter the applicable Rules of 
the Road. The Separation zones are intended to separate inbound and outbound traffic and to be free 
of ship traffic. The separation zones should not be used except for crossing purposes. When crossing 
traffic lanes and the separation zones use extreme caution.
