Third Bridge to Cape Cod,MA

The way the article reads the new bridge would be the only one with a toll. Of course when going the opposite direction across the Sagamore bridge you've already paid a toll unless you used the Bourne bridge which would still be used for both directions,I assume.
Unless they plan on some type of electronic tolling, I don't see how stopping to pay a toll helps traffic flow.
I see it's just one idea under consideration. I wonder what others "ideas" they have ?
