You have two choices - the scenic route that takes you through back roads and winds through gorgeous wooded areas, or the direct route through Chattanooga, Tennessee.
Scenic Route
The scenic route starts by taking Interstate 75 N to Adairsville. In Adairsville, take exit 306 for Hwy 140 W to Armuchee. In Armuchee, this becomes Hwy 27 N, stay on to Summerville. In Summerville, take Hwy 48 W to Hwy 117 (in Alabama). When Hwy 117 splits, take Hwy 40 W to the left. At the bottom of the mountain on Hwy 40 in Scottsboro, turn right onto Hwy 35 N. Go to the 4th traffic light in Scottsboro and turn left onto Willow Street. This will continue as Hwy 35 N. The store is ahead approximately 1.2 miles on the left. This beautiful rural route takes about 2 1/2 – 3 hours.
A few suggestions for this route. First, if it's close to noon, eat lunch before you leave Atlanta. There are plenty of restaurants you're familiar with at several exits as you travel north. The reason is, once you head west, you'll be in more rural areas where fast food is hard to find.
Direct Route
The direct route is simple. Just take Interstate 75 N to Chattanooga, head west on Interstate 24 W to South Pittsburgh (exit 152). In South Pittsburgh take Hwy 72 W to Scottsboro. Go approximately 30 miles and exit on Veterans Drive (Hwy 35 N) and turn right at the traffic light. Take Veterans Drive to Willow Street and turn left at the traffic light. This will continue as Hwy 35 N. Unclaimed Baggage Center is ahead approximately 1.2 miles on your left. It takes about 3 hours to drive the 178 miles between Atlanta and Scottsboro.
