Yeah, some tolls are pretty much impossible to avoid.
I was up in the U.P. just north of the Mackinac bridge and when I asked Apple Maps to take me home it routed me AROUND Lake Michigan. It might have been fun to drive through Wisconsin and visit Chicago and burn the extra 6 hours, but I wasn't really in the mood...
So yes, so many bridges have tolls because they are really hard to avoid sometimes!
