3,200km is very little distance in the context of the USA and it's rural town sprawl. 3,200km might get you from coast to coast in a straight line, but 3,200km probably wouldn't even service every town in California once you take the landscape and numerous dotted towns.

So that's 130,357 kilometers. So at the same cost per km as Denmark, 5,312,500 DKK /km, that's 692,521,562,500 DKK or $105,117,847,971.88 USD, ($105.12 billion) USD.
Not considering how many miles of that is actually through mountain ranges and the extra cost of doing highly remote work.
I don't deny that the US is far bigger. And its density far lower, even in individual states. I'd imagine that does raise costs. But the US is also proportionally richer than Denmark, per capita ($62k vs $52k), not per square km, mind you.
That being said, I do get an impression that more money is lost in bureaucracy/company "fees" in the US than in Denmark.
