One of the constant themes of modern socialism (and Keynesianism) is the belief that we can create prosperity through government spending on roads. Mind you, roads can help an economy if they are located in places where they can aid commerce by making it possible for relatively cheap transportation that permits wider uses of division of labor.
However, that is not why people like Paul Krugman and other socialists champion tax-funded road building. Instead, they insist that the money spent in itself will revitalize the economy, and that is pure nonsense. Interestingly, this past year has seen a huge amount of government "public works" spending, but the effects have not been what the Krugmanites/Socialists have claimed.
