Ohio State Route 528 runs north-south in eastern Lake and eastern Geauga Counties. It begins at US Route 422 in Parkman, and runs north toward Lake Erie. Ohio Route 168 shares a southern terminus with Ohio Route 528, and both routes begin along a road that is already carrying Ohio Route 88 toward the north. Ohio Route 168 soon splits off toward the northwest, and Ohio Route 88 turns toward the east shortly after that. This leaves Ohio Route 528 on an independent course toward the north, across eastern Geauga County. Ohio Route 528 stays rural, flanking Middlefield to the east, and passing through no other towns. Once the route reaches Lake County, it meets Interstate 90 and serves the small town of Madison. The last piece of Ohio Route 528 extends a little farther north to North Madison, where it ends at US Route 20.
My photo for Ohio Route 528 signage comes from the southern end along US Route 422 in Parkman. The triplicate junction marker shown in the photo faces east for westbound travelers on US Route 422. It helps those travelers anticipate the upcoming turn onto Ohio Route 168 northward, Ohio Route 528 northward, or Ohio Route 88 in either direction. This photo was taken during the grand tour of northeastern Ohio in October 2022.
