Ohio State Route 3

State Route 3 is a major north–south highway in Ohio which leads from Cincinnati to Cleveland by way of Columbus. It is the second longest state route in Ohio. Because of this the road is also known as the 3-C Highway, a designation which predates the Ohio state highway system. It is the only state route to enter all three of Ohio's largest cities, though it has largely been bypassed by Interstate 71 (I-71). The route's southern terminus is in downtown Cincinnati at the U.S. Route 27 (US 27)/US 52/US 127 concurrency, which is also the western terminus of US 22. SR 3 and US 22 share the same path for nearly 70 miles (110 km), parting ways in the city of Washington Court House, where SR 3 is joined with US 62. This concurrency runs nearly 40 miles (64 km) to Columbus. From there SR 3 continues solo to Sunbury, where it joins US 36 for just over 24 miles (39 km) until it reaches Mount Vernon. SR 3 ends in Cleveland at Public Square, with the last several miles concurrent with US 42 from Parma. It is one of nine other routes to enter downtown Cleveland at Public Square.
