A 60 kilometre ice highway in Minnesota that takes motorists across the mammoth Lake of the Woods to the northernmost point in the contiguous United States is open for the second straight year, with a toll of US$250 (NZ$370) per vehicle.
The road, which costs an estimated NZ$2210 per mile for ploughing and other upkeep, begins in Warroad and ends at the Northwest Angle resort community, which is known for its ice fishing.
The highway allows people to bypass a drive into Canada or get there in a vehicle rather than a plane or snowmobile.
"Some people say, 'Gosh, I feel like I'm on the moon,' and some people say they think they're in Antarctica or on the tundra," Joe Henry, executive director of Lake of the Woods Tourism, said of driving the ice road.
