Not answering your specific question, but just a heads-up for anyone doing ohio to erie this summer - there's a closed section of the little miami trail north of cincinnati that you'll need to detour around between June 7 and probably end of July. There isn't going to be any posted detour:

The Little Miami Scenic Trail will be closed at Old 3C Highway from June 7, 2021 until mid or late July.
There will be a project on 3C Highway (a.k.a. US 22) in the vicinity of where it crosses the river and the Little Miami Scenic Trail. The project will start June 7, 2021 and is anticipated to run for 40 to 50 days. During the project Old 3C Highway will serve as the motor vehicle detour for US 22 traffic, and because of anticipated increased traffic on Old 3C the decision has been made to
close the Little Miami Scenic Trail where it crosses Old 3C Highway. No trail detour will be provided for this closure.
