AAA Texas on Thursday reported the average price at the pump statewide has reached $3.15 per gallon.
Gas prices nationally rose 6 cents to hit $3.33 per gallon.
The association survey found Amarillo has the cheapest gasoline in Texas at $3.07 per gallon. Drivers in Corpus Christi are paying the most at $3.18 per gallon.
AAA Texas says gasoline prices have been largely flat to start 2014, compared to recent years. Industry officials cited cold temperatures that likely kept drivers off the roads, along with no looming production concerns overseas or regional refinery issues to push gasoline prices higher.
