Ohio gas prices rise again, may continue to climb Feb 21 11:13 AM US/Eastern COLUMBUS, Ohio (AP) - Gasoline prices are up more than a dime from last week at Ohio pumps. The state's average price for regular gas was $3.45 in Monday's survey from auto club AAA, the Oil Price Information Service and Wright Express. That's up 12 cents from the average of $3.33 per gallon a week ago. Drivers were paying an average of about $3.10 at this time last year, before prices climbed to record highs. Some analysts believe gas prices may hit new highs in the next few months. Oil prices have climbed to their highest level this year amid expectations that supplies will tighten in the spring. There's concern that the international dispute over Iran's nuclear program could slow oil supplies from the Middle East.
