.It seems likely they will have to wall off the toll lanes to prevent people from simply going around the toll booths, and they probably won't provide exits except at key points, greatly limiting their usefulness.

The tollway will be walled off, and the "tollbooths" will be entirely electronic (EZ Tag).

According to the schematics it looks like there will be one exit to the mainlanes for every three freeway exits.

A system that already has problems telling when EZ Tag users are on the Tollway frontage roads and the actual tollway, and they are maintaining it will work side by side with normal lanes?

Won't work. The mainlanes will be jammed (they are only going from three to four in each direction) so unless the toll lanes are very sparsely used, there will be long lines at each exit.

I've said it before: Highway design engineers have to be the stupidest people on the planet.
