This article misses the point. It assumes that adding lanes doesn't lead to any other changes. And it totally misses the point of why people are willing to spend money on highways. When you make travel to a destination easier more people will want to live and work there. Soon, that capacity will be used up and everything will go back to being congested. If you told voters: your commute will not get better at all, but we want to spend $1B to enlarge this highway so other people can benefit, no one would ever expand a highway again. So the article is right, as long as you have the wrong model for how cities work and you have the wrong model for why anyone would build a highway.
