History
The SR 163 designation was applied in 1923. Originally, the highway ran along its present routing from its intersection with SR 51, at the time a part of SR 2 and later designated as the now-defunct SR 102, on the outskirts of Genoa, and its eastern terminus near Marblehead. SR 163 was extended west into Wood County along a previously un-numbered road from Genoa to its present western terminus at US 20 southeast of Perrysburg.
