Chicago to Detroit by road
The fastest driving route is 281 miles (452 km) long and takes about 5 hr 15 min without stops or traffic. It runs mostly on I-94 (201 mi), I-90 (32.9 mi), and M-14 (22.2 mi).
It goes through 3 states: Illinois (14.1 mi), Indiana (51.5 mi), and Michigan (215 mi). That’s an average of 53 mph (86 km/h). AAA recommends a break every two hours or 100 miles: with 2 stops of 20 minutes, the trip takes about 5 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 Detroit are 239 miles (385 km) apart. That’s the geodesic on the WGS84 ellipsoid, the distance “as the crow flies”.
The road is 18% longer: for every 100 miles in a straight line you drive 118. That’s a normal detour between two cities. Of the 40 US pairs in this series, it ranks 9th for detour (the average is 14%).
From Chicago, Detroit lies to the east (bearing 80°), and from Detroit, Chicago lies to the west. The straight line reaches Detroit on a bearing of 84°: on a sphere the bearing keeps changing along the way, which is why the shortest route looks slightly curved on a flat map.
Halfway between Chicago and Detroit
Halfway along the straight line, 119 miles (192 km) from each city, is the point 42.1138° N, 85.3566° W. It falls near Scotts (Michigan, pop. 237), 6.3 mi away.
By road, the halfway point is 140 miles (226 km) from each city, near Scotts (Michigan, pop. 237), 10.7 mi away. The two midpoints are 15.7 mi apart: if you want to meet halfway, the one on the road is the useful one.
Time difference and flight
Detroit is 1 hour ahead of Chicago all year (Eastern Time versus Central Time): when it’s 12:00 in Chicago, it’s 13:00 in Detroit.
No flight time is given: under 500 km (311 miles) in a straight line, time at the airport outweighs time in the air.
The two cities
Chicago and Detroit sit at almost the same elevation: 588 ft (179 m) and 598 ft (182 m).
Chicago has 2.7 million people and Detroit 649,095 people (Census Bureau estimate for 2025).
