History

From 1969 to 2007, SR 120 Loop looped around Marietta. In October 2007, SR 120 Loop was decommissioned, and mainline SR 120 was rerouted to the southern part of the loop. Prior to October 2007, mainline SR 120 ran through downtown Marietta and formed the southern part of Marietta Square. The portion of SR 120 from U.S. 41/SR 3 to SR 120 Alternate was renumbered SR 3 Connector. This was done at the same time changes were made to SR 5.
