After they finish the new bridge, then both of them will be made into three-lanes and each will be one-way. But one of the three lanes will be buses only. So it'll end up being two lanes of traffic either way.
Now... the toll will only be charged one way. So that $6 is only a round-trip cost (lucky me!!). Seems that state law prohibits them from putting a toll BACK on the old bridge, since it was already bought and paid for with tolls thirty years ago, when the tolls were taken OFF. But they get around that by making them now both one-way bridges and only charging a toll on the NEW bridge. Sick, ain't it?
