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

The destination clock does not match departure time, so double-check hotel check-in windows and late arrival plans.

Between Columbia, TN and Chattanooga, TN, road signs point toward Knoxville, 840: Knoxville and Murfreesboro.
Columbia is the county seat of Maury County in Central Tennessee, and is 50 miles south of Nashville. It is home to an estimated 38,224 people and hosts a mule day festival the first weekend of April every year. It is more famously known for being the hometown of the 11th President of the United States, James K. Polk. In addition, numerous antebellum homes are located around the city including Ripavilla, the Atheneum, Elm Springs, Rattle and Snap, and Hamilton Place to name a few. It is a city rich in history and culture endearingly known by its locals as "The Dimple of the Universe".
It's safe to say the South has had its moments of racism and racial unrest, but Columbia seems to take it to a higher level. From indiscriminate lynchings as though they were pastimes to a race riot in 1946, racism has seemed pretty systemic here.
Chattanooga is the 4th largest city in Tennessee. It is the seat of Hamilton County. It is in Southeast Tennessee on the Tennessee River and near the border of Georgia. It was immortalized in the popular 1941 song "Chattanooga Choo Choo", made famous by Glenn Miller.
