I remember reading about two instances. In one, I believe, it split the ranch in two (over 10,000 acres). In another, can’t recall if it a town or a university, but again it split it in half. All this property sits directly on the border and straddles it.
Sort of like the Interstates and Freeways have done all over America.
The state and federal governments don't seem to show much concern about the same type of problems caused by limited access roads.
I know of many farmers who cannot get their equipment from one section of their farm to the other and most cities have whole neighborhoods split in two by miles of Interstates.
The government doesn't seem overly concerned about the potential disruptions to thousands of people by the Trans Texas Corridor that will put thousands of miles of 1,200 foot wide limited access road all over Texas.
BUILD THE FENCE!
