I own property in texas and no, it did not particularly scare me. Things like roads are what eminent domain laws are in place for. How much land do you think the state took when they built I-35 in the first place? Just a couple of acres or perhaps hundreds of thousands? I believe the plan was to have the road built at relatively little cost to the state and then allow the corporation that built it to collect tolls and maintain the road for a specified amount of time as payment for building it after which the state could do what they wanted with it. It is not like the corporation could roll up the road and take it back to Spain when they were done, once it was built it would stay. I think that choosing a Spanish company to do it was politically tone deaf but I liked that plan better than hiking everybodys taxes to pay for a state built road. No matter who eventually builds a successor road or widens the existing I-35, I would be very surprised if eminent domain isnt used to whatever degree necessary to acquire the land to do it. I am not saying I like it but that is the way it will likely be done. The only thing I know for sure is that until something is done we definitely have an inadequate main north-south road through central Texas.
