Where is Errol Morris's Minnesota "Road"?

[SlackerInc]

I perked up at this as I used to live in northern MN; but every other cite I find on Google seems to be just quoting this one:

I had proposed another story called Road, about a guy who was so frustrated in his attempts to get the federal government to build an interstate highway across northern Minnesota, he decided he would do it himself. And it led to disaster after he had built less than a mile of his interstate and then he was forced to put in a right-angle turn because he couldn’t buy the adjacent property. And so on and so forth.

Was it supposed to go from Duluth to Fargo? Or something even more quixotic?
