With businesses slowly reopening across the Tennessee Valley, are you putting miles on your car again? Well, most people are and with that, the average price of a gallon of gas should help a bit. Today’s (5-11) average in Chattanooga is $1.71 / gallon which is higher than the statewide average of $1.60 but lower than the national average, which sits at $1.86 / gallon. If it makes you feel any better, the average price per gallon a year ago was significantly higher at $2.48. No. I didn’t think you’d feel better.
