Expanding roadways are an example of induced demand, which means that for some class of things, as it gets cheaper (or qualitatively better/less costly, as in the example of traffic), more people consume it by shifting preferences from alternatives, and in the end it's just as pricey (or qualitatively poor) as before. Is your point that as housing gets cheaper in a place, more people will be housed and eventually the equilibrium goes back higher?
If so, isn't that the goal? More people are still housed than before.
