(CNNMoney) — Gas prices continued their nationwide decline on Tuesday, as South Carolina became the first state in nearly a year and a half to hit an average of less than $3 per gallon.
The statewide average price for South Carolina was $2.987 per gallon of unleaded gasoline on Tuesday, according to AAA. This is the first time that the statewide average in any state has dipped below $3 since Missouri crossed that line on Feb. 22, 2011.
