I-75 is the backbone of this trip, a well-maintained four- to six-lane highway that cuts through eastern Kentucky and western Ohio. The major junctions at I-640 in Knoxville, I-275 around Cincinnati, and I-270 in Columbus are crucial for navigation.

Leaving Knoxville, you climb the Cumberland Plateau through dense hardwood forests. Near Jellico, Tennessee, the highway crests at 2,000 feet, offering glimpses of the Cumberland Gap. In Kentucky, the landscape flattens into the rolling bluegrass pastures of horse farms.

Just south of Lexington, the Kentucky River Palisades form steep limestone cliffs. A detour to the High Bridge (exit 95 on US-27) reveals a 275-foot-deep gorge on the Kentucky River—one of the deepest river gorges in the region.

Local Commerce

• Lexington: Buy bourbon directly at Woodford Reserve Distillery (exit 53 on I-75)
• Georgetown: Factory outlet stores at exit 129
• Cincinnati: Over-the-Rhine district for craft breweries and local art

I-75 in Kentucky has narrow shoulders between Lexington and Cincinnati, so emergency pull-offs are limited. Use official rest areas at mile markers 38 (KY southbound) and 41 (OH northbound) for safe breaks.

For families, the Cincinnati Zoo (exit 9 on I-75) is a top attraction, with a children’s petting zoo and splash area. The Creation Museum (exit 11 in Petersburg, KY) offers interactive exhibits for kids.

Fatigue Management

• Stop every 2 hours: Use rest areas or chain restaurants (Cracker Barrel at exit 41 in Kentucky is a local hub)
• Caffeine: The Buc-ee's in Richmond, KY (opening 2024) will offer 50+ coffee flavors
• Power nap spots: Designated parking at rest areas; some have quiet lounges (e.g., KY welcome center at exit 191)
