RE: Tolls
Joy is right, the term Freeway comes from the fact that such highways are
free as opposed to being Tollways.
And an interesting story about tolls from here in the Pugent Sound area.
After the tolls on two bridges (that I travel frequently in my Westy, VC)
had paid for the bonds used to finance them the State of Washington wanted
to continue the tolls, still wanted the money.  The courts said "No", can't
do that. and the tolls were removed.  One of those bridges was the infamous
Narrows Bridge, the 'Galloping Gerty' that everyone has seen the film of
falling apart in the wind a few months after it was built.  It was replaced
but now, many years later, they are building a second bridge parallel to it
to handle the increased traffic.  It to will be a toll bridge but how much
do you want to bet  that politicians worded the legislation that created it
such that the tolls will be there forever?
