Spanning 339.9 miles across Tennessee, this cross-state journey connects Chattanooga to Memphis in approximately 4 hours and 59 minutes.

Seasonal Notes
Summer travel usually means heavier construction, hotter rest stops, and busier weekend traffic around major cities.
Winter travel shortens daylight, so a route that looks manageable on paper can feel much longer after dark.
Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.
Time zone
1 hour earlier
The destination clock does not match departure time, so double-check hotel check-in windows and late arrival plans.
Temperature spread
3 degrees cooler at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.

More Details
What kind of drive is this?
Expect a turn-heavy local drive rather than a mindless highway cruise on this 339.9-mile transit. While you will utilize major thoroughfares like I-24 and I-840, the route lacks a single, long uninterrupted stretch on the interstate, requiring you to stay alert through various transitions. Because the highway share is 0%, your time behind the wheel will involve frequent course adjustments and navigating local infrastructure. The personality of this drive is practical and utilitarian, prioritizing connectivity between regional hubs over scenic interstate cruising. Prepare for a more engaged driving experience than a standard high-speed commute, as the road demands your attention through its varied turns.
99% highway — fuel and pacing are the main things to plan.
15 navigation steps total — most of the decisions cluster near the start and finish.
