Commuters continue to experience pain at the pump as gas prices keep rising.

The national average price of the gallon of gas has hit $5, the first time that’s ever happened, according to AAA.

For a gallon of regular in New York City, $5.18 is the average price. That price is up 16 cents in just a week and 47 cents in only a month. This time last year, AAA says it was $3.20 for a gallon.

According to GasBuddy.com, the cheapest gallon in the Bronx is $4.79. In Brooklyn, the cheapest is $4.75.

At a gas station in Castle Hill Saturday night, the prices were higher than the average for New York City. Drivers paid $5.57 for a gallon with cash, but $5.72 with credit card.

AAA says that gas prices usually rise in the summer as more people get out on the road. The increased demand, plus supply shortages linked to countries around the world banning Russian oil, also don't look like they're ending any time soon.

They say any chance to use mass transit, walk or carpool is worth doing.

Even though this is the first time gas has cost $5 a gallon nationally, when one factors in inflation, which is also high right now, it's not actually the most expensive it's ever been. According to finance site Kiplinger, that was in the summer of 2008, when gas was $4.11 per gallon, which, adjusted for today's inflation, equals to $5.80.
