It will happen I'm sure, just a matter of time and a lot of red tape. We also deal with it here in the Waco area, as the proposed route is south of here. My last understanding was it had been "narrowed" down to a 10 acre strip, but like you, I haven't found a detailed map that you could really see the detail accurately.
I agree that it's a bad thing to have to face if you're in it's path. You will be compensated, and for more than market value, but I realize if you are not willing to sell, the price won't matter.
Everyone complains about stuff like this.. new roadways, subdivisions, industry, taking up farm and ranch land. But on the flip side, with all the PEOPLE here, what's to be done? Has anyone driven in Austin lately? Dallas? The traffic is horrendous, and only going to get worse every year, as more and more people have to drive places.
There isn't a good solution for stuff like this. It's progress, and progress has to be made to facilitate the world as it changes.
