Mary, Rhea county Tennessee is abt two-three counties east of Tullahoma, Tennessee. Rhea county is north and slightly east of Chattanooga, Tennessee. If I remember correctly (that doesnt mean I do) Hwy 68 runs through there (well only part of it) try US Hwy 27 for Rhea county and US Hwy 41A for Tullahoma, Tenn. Which is in Coffee county Tennessee.
