History

SR 104 is an original state highway with two parts: One from Portsmouth to Waverly, and one from Chillicothe to Columbus. The southern part of the route was decertified when U.S. Route 23 was certified in 1926. This southern route was replaced with the now defunct route number State Route 112. In 1951, the southern part of the route was recertified as State Route 104, connecting to the northern part of the route by overlapping U.S. Route 23. The route close to Portsmouth was concurrent with State Route 73. In March 1951, the Ohio Department of Highways converted an section of SR 104 south of Columbus into a test strip for traffic signs. It was the first in a series of experiments sponsored by the

in four states and five other countries to compare the effectiveness of national traffic sign standards from around the world. A series of 24 signs from six countries were placed along the road along with distance gauges for 30 test subjects. The department abandoned the experiment four days after it started, after the signs attracted unexpected controversy and curious onlookers who posed a hazard. The experiments eventually led to the
