# Ohio State Route 558

State Route 558 (SR 558) is a 15.74-mile (25.33 km) state route that runs between Salem and East Palestine in the US state of Ohio. Most of the route is a rural two-lane highway and passes through farmland, woodland and residential properties.

In 1926, SR 154 was rerouted along its current routing; decommissioning the current route of SR 558. In 1937, SR 558 was established between SR 45 and East Palestine. In this year the road was also paved between East Fairfield and East Palestine. Between 1953 and 1955 the road was paved between Salem and SR 164. The final section of roadway, between SR 164 and East Fairfield, was paved between 1959 and 1961. Between 1979 and 1981, the route was rerouted to the south along some of the former SR 344.
