History
The SR 314 designation made its debut in 1932. It was originally routed entirely within Morrow County, along its present alignment between the SR 95 junction in Chesterville and the US 42 intersection southwest of Lexington.[1][2]

In 1935, SR 314 was extended on the south end. It was routed along previously un-numbered roadways to a new endpoint at its present southern terminus at the US 36/SR 3 duplex in Centerburg.[5][6] Then, in 1939, SR 314 was lengthened on the north end when it was extended along roads that were previously locally-maintained to its current northern terminus at SR 61 south of Shelby.[7][8]
