Not anywhere I've been on a toll road in New England. If I go from Kittery to Kennebunk, I pay the same $3 toll at the York tollbooths as if I drove all the way up to Portland. Bizarrely, there are some interesting loopholes you can hit to avoid tolls by getting on and off at certain exits, as opposed to other neighboring exits.

I commuted the Maine Turnpike for a little over a year, and the difference between naive routing and toll-optimized routing could be five or six dollars a day.
