State Route 3 (SR 3) is a major north–south (physically northeast-southwest) highway in Ohio which leads from Cincinnati to Cleveland by way of Columbus. It is the second longest state route in Ohio. For this reason, the road is also known as the 3-C Highway, a designation which antedates the Ohio state highway system.[2] 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).
