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== *1940 – Original route certified; originally routed along its current alignment from the Michigan state line to Metamora, along currently unnumbered roads from Metamora to U.S. Route 20 in Ottawa Hills by way of Sylvania, along its current alignment from U.S. Route 20 to Downtown Toledo, a currently unnumbered road from Downtown Toledo to east of Toledo, and current State Route 51 from east of Toledo to east of Elmore.〔(Route 120 ) (The Unofficial Ohio State Highways Web Site) by John Simpson〕 *1946 – Routed to its current alignment from Metamora to Ottawa Hills by way of the village of Assumption and concurrent with U.S. Route 20; Metamora to Sylvania decertified; Sylvania to Ottawa Hills certified as State Route 333 (now defunct).〔 *1955 – Rerouted from east of Toledo to the village of Lemoyne along new 4-lane highway; former routing from east of Toledo to Elmore certified as State Route 51.〔 *1959 – Rerouted from Downtown Toledo to east of Toledo along current State Route 65 and Interstate 280.〔 *1962 – Dually certified with Interstate 280 from east of Toledo to east of Toledo.〔 *1966 – east of Toledo to Interstate 80 upgraded to freeway and dually certified with Interstate 280.〔 *1970 – Truncated at its current eastern terminus in Downtown Toledo; from Downtown Toledo to east of Toledo certified solely as State Route 65; east of Toledo to Interstate 80 certified solely as Interstate 280; Interstate 80 to Lemoyne certified as State Route 420.〔 *1972 – Rerouted from west of Downtown Toledo due east to Interstate 280 via Central Avenue; west of Downtown Toledo to Downtown Toledo (Cherry Street) decertified.〔 *1989 – Moved back to its original alignment from west of Downtown Toledo to Downtown Toledo via Cherry Street; alignment to Interstate 280 decertified after Central Avenue interchange with I-280 removed.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ohio State Route 120」の詳細全文を読む スポンサード リンク
