Driving
I-24 southeast past Murfreesboro, up the Cumberland Plateau, and down the Monteagle grade.
Before Chattanooga the interstate dips into Georgia for about 4 miles, and your phone jumps an hour. Atlanta runs on Eastern time. At Chattanooga you pick up I-75 the rest of the way.
Call it 250 miles. Your maps app knows the hours for the day you leave better than we do.
Flying
Southwest carries the biggest share of passengers at BNA, and both Southwest and Delta fly nonstop to ATL. Leaving the car at home? The WeGo Route 18 bus runs between BNA and downtown.
In Atlanta, MARTA's Airport station is inside the Domestic Terminal, and the Red and Gold lines run to Five Points downtown or on to Midtown. You can reach the city without a rental car.
March in Atlanta
Highs in the mid 60s, nights in the mid 40s, pack a rain layer. A few degrees warmer than March at home. For the pollen picture, see the Atlanta page.
Spring is thunderstorm season across Middle Tennessee. Check the forecast before you take on the Monteagle grade.
