2 days ago I drove from Clive, Iowa to Indianapolis in 7 hours with one stop of about 20 minutes to get gas and eat. There was very little construction. Even in the construction areas both lanes seemed to be open on I 74. I don't know if that was because it was Thanksgiving or not. Fair disclosure I set my cruise control at 78 mph in Des Moines and keep it that way pretty much the entire time, so if you drive slower keep that in mind.
