The best way to determine the commute is to drive it yourself during a week day. I'd wait a week or so to make sure all the kids are back in school as well.
Good luck to you!
You'll fare better going up in the latter part of your commute window in the morning. 680 N can be a parking lot at 8am. At 9:30 it should be pretty much a speed limit ride.
The ride back, not so good. Your crush is due to the 24 junction and all the traffic it dumps on 680. I'd say 40-45 minutes for the pm ride.
