You can expect to spend approximately 5 hours and 28 minutes behind the wheel, making it a manageable day trip if you get an early start.

Drive Character

This trip is a quintessential highway-focused drive, with 95% of your travel taking place on high-speed roads. You will spend the vast majority of your time on I-55, which accounts for a 256.4-mile stretch of the journey. Because such a high percentage of the route is interstate, the driving experience is consistent and efficient rather than technical or winding. You should anticipate a steady, monotonous pace as you cruise north, requiring focus during the long interstate segments. The transition from local streets like College Avenue to the open highway happens early, allowing you to settle into a predictable rhythm for the remainder of the trip.

Most of the miles stay on highways, which makes pacing and fuel planning easier than turn-by-turn city driving.

There are about 28 navigation steps in the underlying route data, so the final approach matters more than the middle miles.

I 55 is the longest continuous segment at about 256.4 miles.

Arrive at destination

Trip Plan

Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.

Time zone

Same local time

Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.

Temperature spread

11 degrees cooler at arrival

A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
