It sounded mostly critical of the TTC, and that is understandable. If they don't try to build overpasses or underpasses for every paved road crossing the ROW, they're gonna rue the day they implement this road.
As far as exits go, it would probably be something like the Pennsylvania Turnpike or Florida's Turnpike (low exit density except near urban areas). The problem is the low overpass density. In contrast, the Pennsylvania Turnpike, which I've driven on, has numerous overpasses. The TTC better have numerous FREE overpasses, likewise, or else the sponsors of HB 3588 will be out on their asses.
But that is not the big bad news for Texas towns like Atlanta and Cass County Texas.
In addition to losing tax revenue from the land taken for the ROW, slicing up of agricultural tracts will probably depress taxable land values.
Worse, with Marshall and I-20 to our south, and I-30 and Texarkana to the north of us, the likelihood of a TTC access point in Cass County is slim to none. Almost certainly we will lose much of the cash flow (now derived from US 59 traffic) upon which most of the area's economy now depends.
Bottom line: the TTC would be the economic death of most rural Texas counties through which it passes.
