---- — Regional gas prices spiked last week. Tracking by the auto club AAA showed that the average price for self-service regular gas rose by more than 10 cents per gallon in both Massachusetts and New Hampshire during the seven-day span that ended Wednesday. It was the sixth straight week in which gas prices across the two states rose.
As of Wednesday, the price for self-service regular averaged more than $3.90 in Massachusetts, according to AAA. The New Hampshire average remained slightly below the $3.90 mark.
The overall national average also rose last week for the sixth consecutive week, the auto club reported. But the increase was more moderate, and the coast-to-coast average is lower than both the Massachusetts and New Hampshire levels.
The Massachusetts state-wide average reached $3.908 on Wednesday, a 10.8-cent increase from the prior Wednesday’s average of $3.800 for self-service regular gas. Wednesday’s figure was 23.0 cents higher than the Bay State average of $3.678 recorded on the same day last year.
New Hampshire saw a 12.9-cent increase last week. On Wednesday the auto club put the Granite State average at $3.881, compared to $3.752 seven days earlier. On the same day of 2011, New Hampshire’s state-wide figure of $3.640 was 24.1 cents lower than Wednesday’s level.
The U.S. national average rose 3.4 cents during the seven-day period, to $3.858 on Wednesday from $3.824 the prior week, according to AAA. Wednesday’s national average was 20.9 cents above the $3.649 recorded on the same day last year.
