Chicago to Kansas City distance

Chicago to Kansas City by road

The fastest driving route is 509 miles (819 km) long and takes about 9 hr 35 min without stops or traffic. It runs mostly on I-55 (199 mi), US 24 (149 mi), and I-72 (108 mi).

It goes through 2 states: Illinois (299 mi) and Missouri (209 mi). That’s an average of 53 mph (85 km/h). AAA recommends a break every two hours or 100 miles: with 4 stops of 20 minutes, the trip takes about 10 hr 55 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, Chicago and Kansas City are 411 miles (662 km) apart. That’s the geodesic on the WGS84 ellipsoid, the distance “as the crow flies”.

The road is 24% longer: for every 100 miles in a straight line you drive 124. That’s a normal detour between two cities. Of the 110 US driving pairs in this series, it ranks 12th for detour (the average is 16%).

From Chicago, Kansas City lies to the southwest (bearing 245°), and from Kansas City, Chicago lies to the northeast. The straight line reaches Kansas City on a bearing of 240°: on a sphere the bearing keeps changing along the way, which is why the shortest route looks slightly curved on a flat map.
