No problem, glad to help out.
According to the TripTik the construction is sporadic. Construction on I-80 in a few areas while in Michigan, a few areas of I-76 in PA and again on 283 in or around Lancaster, after that it seems to be fine.
A car hauler?? You bringing a car or taking one home with you?

From my experience most roads are pretty well posted if there is a deer problem. Lets hope that you don't encounter any!
Have a safe trip!
