I-69 became part of the TTC but then it got separated from the TTC. Some parts might be toll, but only if it's new capacity.
If you want to know EVERYTHING about I-69, like I feel I do, read a really amazing book called "Interstate 69, The Unfinished History of the Last American Highway." I heard the author on a Dallas radio show and he knew it all. Spent more than five years going all up and down from Mexico to Canada and he found the small group of people who had the whole idea. It blew my mind and the book is an easy interesting read.
any chance of getting those maps online ?
Wasnt' the Trans Texas Corridor and I-69 one and the same project ?
