Ohio State Route 199
Ohio State Route 199 is a north-south highway in northwest Ohio. Its southern terminus is at an interchange with US 23 just south of Upper Sandusky, and its northern terminus is at US 20 and SR 795 in Perrysburg.
The route begins northerly into Upper Sandusky, and then on to Carey, where it joins US 23. The two routes run concurrently from Carey to Fostoria. From there, SR 199 continues to West Millgrove and to US 6, whose route it joins for a mile as it crosses the Portage River. The route then continues north to Perrysburg. It passes over I-75 south of Perrysburg, but does not have an interchange with it.
