Having seen the construction on I-65 in Indiana on the way down during the day -- and the construction on I-70 in Indiana as well! -- we decided to take the diagonal home. This worked well, dodging essentially all of the construction except for a tiny bit on U.S. 30 near Van Wert. Even so, it took us six and a half hours on the road to make it home, so we pulled in at about quarter to one.
And, boy, were we tired! :)
