Waco!
Bell, TN
Southern Illinois
what is the halfway point between Birmingham, AL and Gainesville, GA?
I'll assume you mean the Waco in Texas and the Denver in Colorado. There are at least three others of each. The halfway point is Amarillo. There's only one of that.
Abbott, Texas, about 15 minutes north of Waco and roughly 4 hours and 5 mins from Bossier and San Antonio
hwy 71 and I10 west is a good halfway point, if you are traveling I10. Going 290, it would be where the Interstate makes a 90 degree turn (Im not sure of the town).
Waco is 164 Miles from Houston
Hewitt, Texas
Hewit just south of Waco is pretty close
Italy, TX
The halfway point is Jane, Missouri.
