Numbered highways in Ohio
Template:Short description Template:Use American English Template:Use mdy dates Template:Infobox state highway system
The Ohio Department of Transportation (ODOT) is responsible for the establishment and classification of a state highway network which includes interstate highways, U.S. highways, and state routes.<ref>Ohio Revised Code 5501.11</ref> As with other states, U.S. and Interstate highways are classified as state routes in Ohio. There are no state routes which duplicate an existing U.S. or Interstate highway in Ohio.
Ohio distinguishes between "state routes", which are all the routes on ODOT's system, and "state highways", which are the roads on the state route system which ODOT maintains, i.e. those outside municipalities,<ref>ORC 4511.01(II),(JJ); ORC 5511.01</ref> with a special provision for Interstate Highways.<ref>ORC 5521.01</ref> Besides the state highway network, there are various county and township road networks within the state.
ODOT permits business routes but only "where an ODOT-maintained highway has been constructed on a new alignment which bypasses the CBD [central business district] of a municipality and no other ODOT-maintained highway provides a direct two-way connection between the bypass route and the CBD, or where the existing guide signing does not adequately direct the driver from the bypass route to the CBD and back to the bypass route."<ref>Template:Cite book</ref>
History
Template:See also Template:Expand section The Ohio Inter-County Highways were created on June 9, 1911, with the passage of the McGuire Bill (Senate Bill 165, 79th Ohio General Assembly).<ref>Template:Ohio road map</ref> Main Market Roads, the most important of the system, were defined on April 15, 1913.<ref>Template:Cite act</ref>
In 1923 the numbering system was simplified. It was altered further in 1927 in order to accommodate numbers in the United States Numbered Highway System.Template:Citation needed
In 1935 the Ohio General Assembly passed a law which added 5,000 miles of roads to the state highway system over a 12-month period.<ref>Template:Cite act</ref><ref>Template:Cite news</ref> These roads were assigned route numbers in the 500s, 600s, and 700s.<ref>Compare:
