In Morgan County, SR 62 enters the Eastern Time Zone, leaving farmland and becoming very curvy (and becoming Nashville Highway) as it heads east through the mountains of the Cumberland Plateau.

SR 62 continues eastward and goes through Lancing and becomes even curvier, before coming to an intersection with US 27/SR 29 (Morgan County Highway) north of Wartburg.

They then pass just east of downtown before SR 62 separates from US 27/SR 29 and continues southeast (as Knoxville Highway) as a four-lane and then exits Wartburg.

The highway continues through Oliver Springs and then Separates from SR 61 and enters Oak Ridge (as Illinois Avenue).

The highway narrows to a two-lane for short distance before widening back out to a four-lane and intersecting SR 169.
