Like I said, it's possible I'm misunderstanding something about the tolls, but that's my interpretation.
The other piece of the "new deal" that seems to be new is the wording about the Americans having approval about changes to the tolls - Reuters says this means the US can veto any toll hike over 10% of the current value, which...I don't know, it seems like such a hike would be in their best interests to approve should it be proposed, since it would lead to more of the net revenue they seem to care so deeply about.
I'm also unclear about whether the "regional investment" the new deal refers to is some kind of new money unrelated to tolls. It would be nice to get clarity there.
