This is commonly called the Bridge-to-
Bridge channel. Large vessels and
towboats depend on this channel for
their safe navigation. Railway or
highway bridges which open for ship
navigation often operate on this
channel.
Bridge-to-Bridge stations must reduce
power to one watt for routine
operations.
