(The Center Square) – Previously surging up before the Thanksgiving holiday, transportation energy prices in North Carolina on Monday are in retreat and just 2 cents above a mark not seen in just over 15 years.

For a gallon of unleaded gasoline, the average from Murphy to Manteo dipped to $2.74. That’s 2 cents higher than in March 2010, 6 cents lower than seven days earlier, and a dime better than a year ago. Diesel is at $3.52 for an average, according to AAA.
