Ohio State Route 574 is a short north-south connector road in Guernsey and Noble Counties. It stays near the western bank of Senecaville Lake for its entire length; this is in an area a short distance southeast of Cambridge, Ohio. The northern end is at Ohio Route 313 east of Senecaville. The southern end is at Ohio Route 566, which continues south to Ohio Route 147. Ohio Route 574 passes through no towns; I think it's just meant to help provide access to the lake.
My photo for Ohio Route 574 shows the first southbound trailblazer, intended to reassure travelers who turned off of Ohio Route 313. I usually avoid taking photos of signage for southbound travelers, because the sun usually ruins these photos. When it's overcast, however, anything is fair game! This photo was taken on a cloudy day in March, 2021, as I was reaching a later portion of my grand tour of southeastern Ohio.
