A rough estimate would be Amarillo, Texas.
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).
The state line of Louisiana and Mississippi is about the halfway point.
The halfway point between Dallas, Texas and Warren, Ohio is in Centerville, Tennessee.
