A significant rise in gas prices may be coming soon. The Colonial Pipeline explosion in Shelby County involved a gasoline supply line that stretches from New York to Texas, providing gas to about 50-million people. Prices could increase by 15 cents in some areas. Alabama average gas price sits at $2.05 and is among the lowest in the country. Monday's explosion comes after the pipeline leak back in September, which left some gas stations dry. Prices will depend on how much time it takes to get the pipeline operational again.
