Ohio State Route 225

State Route 225 was first designated in 1924, though initially it ran along part of what is now Alliance Road in Portage County, extending from the current U.S. Route 224 to the south and ending at State Route 14 in the small town of Yale to the north.[2][3]

In 1931, State Route 225 was routed along what is now the northern section of State Route 183 from Atwater Center north to Edinburg.[4][5] By 1937, it was again rerouted and extended, returning to its original location to Yale, but this time going 3 miles (4.8 km) further north to State Route 18, and extending south to Alliance along its current alignment south of U.S. Route 224.[6][7] As part of the construction of the new Interstate 80S, part of SR 18 was rerouted onto the new freeway by 1966, leaving the northern terminus of SR 225 at the former SR 18 (Tallmadge Road). By 1969, the northern terminus of SR 225 was moved back to SR 14 in Yale as the section of SR 225 between Yale and SR 18 was decommissioned.[8] In 1970, State Route 225 was rerouted once again to its current alignment, turning east along U.S. Route 224 to Deerfield Center and then turning north at State Route 14 along what had previously been designated State Route 627.[9]
