Thanks for the ping, TSR! This is one of the most comprehensive and balanced articles on the TTC that I've seen yet...
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.
