Many major east–west transportation corridors go through Ohio. One of those pioneer routes, known in the early 20th century as "Main Market Route 3", was chosen in 1913 to become part of the historic [[Lincoln Highway]] which was the first road across America, connecting New York City to San Francisco. In Ohio, the Lincoln Highway linked many towns and cities together, including [[Canton, Ohio|Canton]], [[Mansfield, Ohio|Mansfield]], [[Wooster, Ohio|Wooster]], [[Lima, Ohio|Lima]], and [[Van Wert, Ohio|Van Wert]]. The Lincoln Highway's arrival in Ohio was a major influence on the state's development. Upon the advent of the federal numbered highway system in 1926, the Lincoln Highway through Ohio became [[U.S. Route 30 in Ohio|U.S. Route 30]].

Ohio is home to {{convert|228|mi|km|0}} of the [[National Road]], now [[U.S. Route 40 in Ohio|U.S. Route 40]].

Ohio has a highly developed network of roads and interstate highways. Major east-west through routes include the [[Ohio Turnpike]] ([[Interstate 80 in Ohio|I-80]]/[[Interstate 90 in Ohio|I-90]]) in the north, [[Interstate 76 in Ohio|I-76]] through [[Akron, Ohio|Akron]] to [[Pennsylvania]], [[Interstate 70 in Ohio|I-70]] through [[Columbus, Ohio|Columbus]] and [[Dayton, Ohio|Dayton]], and the [[Appalachian Highway (Ohio)|Appalachian Highway]] ([[Ohio State Route 32|State Route 32]]) running from [[West Virginia]] to [[Cincinnati]]. Major north–south routes include [[Interstate 75 in Ohio|I-75]] in the west through [[Toledo, Ohio|Toledo]], Dayton, and Cincinnati, [[Interstate 71|I-71]] through the middle of the state from [[Cleveland]] through Columbus and Cincinnati into [[Kentucky]], and [[Interstate 77 in Ohio|I-77]] in the eastern part of the state from Cleveland through Akron, [[Canton, Ohio|Canton]], [[New Philadelphia, Ohio|New Philadelphia]] and [[Marietta, Ohio|Marietta]] south into West Virginia. Interstate 75 between Cincinnati and Dayton is one of Ohio's most heavily traveled sections of interstate.
