As Americans plan set off on the first serious road trip of summer, gas prices are surging at the pump due in part of a global rally in the price of crude oil, the auto club AAA said.

In its weekly report, AAA says the national average price for a gallon of unleaded was $2.70, compared with $2.66 a week ago. Still, prices are nearly a dollar lower than a year ago.

Motorists in Michigan are paying less than the national average – about $2.62 a gallon – about 10 cents more a gallon than a week ago. The hike is the fourth in the past five weeks.

AAA said Michigan’s cheapest gas was $2.58 in the Flint area, while gas was going for about $2.66 a gallon 60 miles away in the Ann Arbor area.
