Columbus to Cincinnati by road
The fastest driving route is 107 miles (172 km) long and takes about 2 hr 5 min without stops or traffic. Almost all of it is on I-71: 104 mi of 107 mi.
The whole route stays in Ohio. That’s an average of 51 mph (82 km/h). AAA recommends a break every two hours or 100 miles: with 1 stop of 20 minutes, the trip takes about 2 hr 25 min. The time is OSRM’s estimate with OpenStreetMap data: no traffic and speeds somewhat below the limits, so real trips can differ.
Straight-line distance and bearing
In a straight line, the shortest distance over the Earth’s surface, Columbus and Cincinnati are 100 miles (161 km) apart. That’s the geodesic on the WGS84 ellipsoid, the distance “as the crow flies”.
