Ohio State Route 603 runs from Plymouth to Malabar Farm State Park, bypassing Mansfield to the north and east. The northern end of Ohio Route 603 in Plymouth occurs at Ohio Route 61. It shares a northern terminus with that of Ohio Route 98. From Plymouth, Ohio runs southeastward across northern Richland County. When Ohio Route 603 enters Ashland County, the route bends toward the south. The southern extent of the route passes the entrance to Malabar Farm State Park, and Ohio Route 603 ends shortly afterward at Ohio Route 95.
My photo for Ohio Route 603 comes from the route's intersection with US Route 42 between Mansfield and Ashland. Travelers who turn off of US Route 42 toward the north will see this scene featuring a northbound trailblazer. This photo was taken in October 2022 during my tour all around the northeastern quarter of Ohio.
