The freeway enters Tennessee directly in the Chattanooga metropolitan area, where it intersects with I-24. Exiting Chattanooga to the northeast, I-75 passes through an area known for dense fog. Twelve people were killed and 42 were injured in a 99-vehicle accident on that stretch of I-75 in heavy fog on December 11, 1990. I-75 does not meet any other highways until it overlaps Interstate 40 near Farragut and heads eastbound. Together, they enter the outskirts of Knoxville, where I-75 overlaps itself with a different road, this time I-640, but only for a short time. When the two meet I-275, I-75 encounters some of its highest points of elevation through the Cumberland Mountains and Cumberland Plateau region, cutting through the uppermost peaks and ridges of the mountains.
I-75 continues northbound through the hilly, rugged terrain of the Cumberland Plateau region of Kentucky passing through London and Richmond, eventually reaching Lexington, where it briefly runs concurrently with I-64 before splitting off for Cincinnati, Ohio. Near Walton, I-71 merges with I-75, making for yet another overlapped portion of freeway. I-275, which is the Cincinnati beltway, is then intersected by I-71/I-75. After passing through Covington, the freeway crosses the Ohio River via the lower level of the Brent Spence Bridge (while the southbound direction uses the upper level) and continues into Cincinnati.
