Drove through the Louisville area on September 7 and 8, and was surprised to see gas prices upwards of 50 cents higher than the rest of Kentucky. Saw $1.759 to the south, but most prices in Louisville were $2.299/gal. New Albany, IN had $2.339. So is there an extra gas tax for Louisville, or does the city/Jefferson County just gouge area residents and travelers to match Indiana?
RFG. Gas prices are typically higher in Jefferson, northern Bullitt, and western Oldham counties than in surrounding areas due to the requirement that RFG be sold in Louisville. It used to be that the cutoff line was the Salt River bridge on I-65, meaning prices south of the river were cheaper than at Shepherdsville and north. That cutoff line may have been extended northward to the Jefferson/Bullitt county line.
For years, the cheapest places around Louisville to buy gas were the truck stops south of the Salt River bridge, at Simpsonville in Shelby County, and the truck stops at the KY 146/KY 157 exit on I-71.
Last few times I've been in downtown Louisville, gas was cheaper across the river in Indiana than it was at some of the stations along I-65 in downtown.
