(WXYZ) - Labor Day weekend is right around the corner, and if you're one of the millions expected to hit the road, you may have noticed a spike in the gas prices.
AAA says over 30 million Americans will hit the road for Labor Day weekend.
That has some affect on the prices, because of supply and demand. Another factor has to do with the fact there are more exports and imports this week.
Also, there was a fire at the BP Chicago refinery Wednesday night that is driving prices up.
That's expected to keep prices high for at least the next couple of days.
Prices are still lower than last year, and the lowest for early Augsut since 2010.
This year, the average price in the state is $3.43 a gallon, compared to $3.52 last year.
