Ohio State Route 104

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 {{convert|8+1/2|mi|adj=mid||-long}} 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 United Nations 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.{{cite news|title=Ohioans tell Europe to keep its signs|agency=United Press|work=Mansfield News Journal|date=March 27, 1951|page=11|url=https://www.newspapers.com/clip/94492201/|via=Newspapers.com}} The department abandoned the experiment four days after it started, after the signs attracted unexpected controversy and curious onlookers who posed a hazard.{{cite news|title=Foreign Road Sign Test Arouses Some Criticism|agency=Associated Press|work=The Independent|location=Massillon, Ohio|date=March 27, 1951|page=12|url=https://www.newspapers.com/clip/94492382/|via=Newspapers.com}}{{cite news|title=Road Sign Test for UN Given Up|agency=Associated Press|work=Daily Press|location=Newport News, Virginia|date=March 30, 1951|page=13|url=https://www.newspapers.com/clip/94492425/|via=Newspapers.com}} The experiments eventually led to the Vienna Convention on Road Signs and Signals, which was adopted in many countries but not the United States.

Since 1968, SR 104's northern terminus has been extended twice – to U.S. Route 23 in 1968 and to U.S. Route 33 via freeway in 1989 – and its southern terminus has been extended twice into Portsmouth in 1972 and to U.S. Route 23 in 1974.

In 1998, a section of SR 104, concurrent with SR 73, in Scioto County had its grade raised out of the flood plain to prevent recurring flooding on the roadway in a $3.8 million project.{{cite web|url=http://www.dot.state.oh.us/Divisions/Communications/transcript/Transcript%20Archive/dec98.pdf|title=Transcript: The Ohio Department of Transportation Newsletter|publisher=Ohio Department of Transportation (ODOT)|page=19|date=December 1998|access-date=February 22, 2020}}

In 2010, a section of SR 104 north of Chillicothe to SR 207 in Ross County was widened into a four-lane highway. $6.5 million out of the $10.6 million cost to widen were from funds from the American Recovery and Reinvestment Act.{{cite news|url=http://www.dot.state.oh.us/districts/D09/NewsReleases/Pages/Ross-104ProjectProgressingTowardCompletion.aspx|title=Ross-104 Project Progressing Toward Completion|publisher=Ohio Department of Transportation (ODOT)|date=June 17, 2010|access-date=March 30, 2018}}
