oneway=yes
psv:oneway=-1 (for a way in which traffic flows in one direction, but
the opposite for busses

oneway=yes
psv:oneway=no (for a way in which busses could potentially travel in
either direction but everyone else can only travel in one)

You can do any <vehicle class>:oneway=* tag, but be aware that not all
make sense, and the default for <class>:oneway=* tags is the same and
the oneway=* tag.

foot:oneway=no (redundant)
foot:oneway=yes (do these exist?)

It seems like loc_name is redundant and unnecessary in this case, and
bridge=ferry isn't well-enough known tag to be understood (route=ferry
is what you're looking for).  But, since it's a bridge, the ferry tags
are wholly inappropriate.  It's a bridge, give it the appropriate
highway=tag, bridge=yes, and give the hours of operation and fee=yes to
indicate that it's a toll bridge.

bridge=ferry makes me wonder if you really meant something closer to the
design of this beast:
http://en.wikipedia.org/wiki/Lacey_V._Murrow_Memorial_Bridge

Anybody who has lived in the Pacific Northwest for very long knows that
Washington State DOT has the world's largest inventory of floating
bridges, and absolutely zero luck keeping any Puget Sound bridge up
(most of the floating bridges sank, some more than once, and the
"Galloping Gertie" nickname managed to carry over to the new Tacoma
Narrows bridge, even though it doesn't apply since being rebuilt after
it's famous 1940 collapse).

Anyrate, anybody who has lived near the Columbia River and is old enough
to vote can has likely crossed a toll bridge similar to the one you gave
an example of, and if you go a generation older, can remember when the
toll plazas (and thus the bridges) closed at night.  Some, like Bridge
of the Gods, the Interstate Bridge and Bridge of the Gods had tolls
recently enough that there are still toll plaza remnants (islands and an
overhead cover at Astoria, toll booths with "NO TOLL - DO NOT STOP"
signs at Bridge of the gods, toll booths boxed into the center median
and shoulder by jersey barriers on the north end of the Interstate).
