Average gas prices in Chicago are now higher than anywhere in the United States, driven higher by a combination of refinery issues and the annual transition to a more costly summer blend, the Chicago Tribune reported June 7.
Drivers in the city are now paying an average of $4.55 a gallon, according to AAA, which is 20 cents higher than a week ago. The price for a gallon of premium unleaded is approaching $5, reaching $4.95 overnight. On this day last year, drivers were paying $4.12 per gallon.
Nationwide, the average price for a gallon of gas is $3.63, up about 9 cents from a month ago.
