The most interesting part of the article to me is this bit:
Much of the tens of billions of dollars that will be spent on roads, for instance, will be funnelled through the states. As a result, a disproportionate amount of the money will be spent in rural areas (which exert disproportionate influence on state governments), leaving cities—which happen to have most of the people and most of the traffic—shortchanged. The top eighty-five metropolitan areas in the country are responsible for about three-quarters of the country’s G.D.P. Yet less than half of the road money will be invested there.
I have an economist friend whose pet peeve is all the ways we, as a country, subsidize rural living - no doubt this will displease him. But I wonder, goods have to get from metro area to metro area, so don't they often travel through rural areas? I am not sure a comparison of GDP is the right metric here. I am not convinced that rural stretches of interstate are less important than urban stretches.
