Why Is Gas Cheaper In Northport, Alabama? Get our free mobile app I'm sitting here steaming as I wait in traffic to cross the bridge into Northport, just to buy cheaper gas. Gasoline is at least 10 cents cheaper a gallon in Northport compared to Tuscaloosa. Sometimes gas is 20 cents cheaper a gallon in Northport. If you drive a truck or SUV that holds 25 gallons, like mine does, it adds up quickly. That’s a case of beer a week! That’s a chicken wing dinner at Baumhower’s! That’s Chinese delivery from Mr. Chen’s! Today, near my home in Tuscaloosa, gas was $2.89 a gallon. Over the bridge in Northport gas was $2.71 a gallon. This makes absolutely no sense. Why the consistent gas price discrepancy? I understand a few cents here and there, but this is consistently more than a few cents. Gas is definitely cheaper in Northport.
