Elon Musk recently announced that he is fed up with traffic in Los Angeles and will soon begin boring a tunnel under the city to relieve congestion. As a billionaire and innovator, Musk has the resources to make something like this happen. But even if he bores his tunnel, where does that leave the rest of the country with its congested highways, crumbling bridges, aging water systems and fragile power grid? One big push in L.A. doesn’t solve the problems of an entire country struggling under the burden of billions of dollars in deferred maintenance. We need a national vision to pay for and revitalize our infrastructure for all Americans.
