There are about 6 stations all within a block of each other at this Exit 4 location. Its grid lock trying to get through there.
Derry - While gas prices statewide remain well over $2.60 for a gallon of regular, drivers passing through Derry and Londonderry on Interstate 93 are continuing to reap the benefits of a price war that broke out last weekend between a handful of competing gas stations at Exit 4.
Yesterday afternoon, the price of a gallon of regular unleaded gasoline sat steady at $2.25 at four different gas stations, all within half a mile of the Exit 4 interchange. Managers at several of the stations said it has been an all-out gas war since last Saturday morning when the managers of Route 102 Gas & Services station began dropping their prices.
