UDOT recently published a set of detailed maps of the final configuration that are available on the project website, but I figured I'd post them here anyway.
Timpanogos Highway interchange (SR 92):

2100 North interchange (SR 194):

Frontage roads:

Active transportation:

Access to/from I-15:

It's going to be very strange getting to I-15 south from 1200 West. That'll involve crossing under the freeway, then a Texas U-turn, followed by a flyover ramp over eastbound 2100 North before finally merging onto 15.
