State Route 120 (SR 120) is an east–west state highway in the northwestern portion of the U.S. state of Ohio. Its western terminus is at the Michigan state line, where an unnumbered county highway (Morenci Road, formerly M-120) continues west-northwest. State Route 120’s eastern terminus is in Toledo at State Route 65; the route is, for all practical purposes, a spur of U.S. Route 20, which generally bypasses Toledo to the west and south.
History
In 1940, Route 120’s original route was certified. It began at the Michigan state line, connecting with the former M-120 near Metamora. SR-120’s current alignment from the state line to Metamora is original to the route. East of Metamora, SR-120 used Sylvania-Metamora Road, Erie Street and Monroe Street to enter Sylvania. The route then turned south on Main Street and Holland-Sylvania Road to leave Sylvania. SR-120 then continued south to U.S. Route 20 (Central Avenue) near Ottawa Hills. SR-120 was co-signed with US-20 from Holland-Sylvania to Reynolds Road, where US-20 turned south. Route 120 continued east from Reynolds Road along Central Avenue. Its alignment along Central Avenue to Cherry Street in Toledo has been unchanged since its inception. At Cherry Street, the route turned south, traveling through Downtown Toledo and over the Maumee River. SR-120 then used Main Street, Starr Avenue and East Broadway to make its way to current State Route 51 (Woodville Road). Route 120 then traveled along Woodville Road from Toledo to its eastern terminus east of Elmore. The section from Sylvania to Toledo replaced State Route 263 and the section from Toledo to east of Elmore replaced State Route 102
In 1946, the route east of Metamora was decertified by the state. The section west of Toledo was renumbered State Route 102, which turned south in Metamora along current State Route 64 to the village of Assumption, then joined US-20 and ran east into Toledo. The section from Sylvania to near Ottawa Hills (Main Street/Holland-Sylvania Road) was designated as State Route 333 (now defunct).
