I would love this. While they're at it, I wish they would tear down the current highway and return to the old one that existed in 1970. Then put governors on all cars restricting them to about 50 miles an hour so as to discourage all the midwesterners from visiting my fair village in the mountains of Colorado. Is this sufficiently luddite? Well, we survived quite well before 1970 and we can live with that old "crummy" road once again.

Progress and wider roads have brought us noise, pollution, and thousands of people who simply drive by our town with no notion of where they are or where they are going but mostly concerned with how fast they can go.  

Gravel roads would do wonders for slowing down the traffic.  

Gravel roads is not something to wish for. They increase the wear on cars, encourages larger cars with heavier suspension due to less comfort and they are not good for bicycling.

My impression is that the lifelenght of a road depends on the roadbed quality and the axle weight of the heaviest traffic. Low quality paving seems to be almost a waste of effort since doubling the material used more then doubles the life lenght.
