Missourians are feeling the pinch at the pump again.

Gas prices have reached almost four dollars a gallon at some stations in the state.

It’s not just a Missouri problem though. Mike Wright with Triple-A says the Midwest has been hit especially hard by rising gas prices.

“It’s more unique to mid-America from Missouri North,” Wright Says. “It has to do with constrictions and the availability of product.”

Missouri typically boasts one of the lowest average’s for gas prices across the nation. However currently Missouri is ranked 29th.

“It’s not so much a demand problem but it’s a supply problem. We’ve got some refinery issues in several locales that supply the general market in Missouri and in addition to that we have some distribution problems.”

As of Friday morning, prices around St Joseph were at $3.79 per gallon. The cheapest gas is 3.12 for a gallon of regular unleaded in the Bootheel. Motorists in St. Louis County are the hardest hit with gas prices there at 3-95 a gallon.

Wright says gas has gone up an average of 30 cents a gallon throughout the state.
