I don't have any reason to doubt this, and I thought you might like to know. You might be able to use it for NAC. A friend of mine said she was bicycling over near the riverfront at the Jeffersonville/Clarksville line where restaurant row and the park come together. She said she saw this big highway sign that will be put up on I-65 somewhere. The sign says: "Last Exit Before Tolls Begin."
In New Albany, the Bored of Works already has approved a wayfinding signage project for the forthcoming tolling era.
