Ohio State Route 199
State highway in northwestern Ohio, US
Ohio State Route 199 (SR 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 (1.6 km) 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.
History
Most of SR 199 was formerly the route of US 23. Before 1966, SR 199 was truncated at the south in Fostoria, followed most of the current route of US 23, and was truncated at the north just east of Toledo, Ohio. In 1966, SR 199 was extended along its current route to Upper Sandusky along US 23's current route from Fostoria to Carey and its old route from Carey to Upper Sandusky.

Why this record matters
The phrase “state highway in northwestern Ohio, US” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 2, 2025. The linked authority identifier is Q2492114. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1966.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
