We have driven several sections of the Lincoln Highway. A section of route 30 in western Pennsylvania is actually signed as the Lincoln Highway.

There were some steep hills, so we won't drive the MH that way again.

We also traveled route 30 across Ohio from I71 to Fort Wayne IN. All good divided highway with no tolls and far less trucks than the Interstates.
Lastly, we have several times traveled route 30 across Nebraska between Grand island and Ogalalla. It parallels I80 there. A relaxing drive on a good 2 lane road with little traffic.
