You know it’s bad when Ashton Kutcher is Tweeting about road closures. Route 405 in Los Angeles is due to be closed for construction this weekend – an event predicted to be so paralyzing for L.A.’s traffic that it’s been dubbed “Carmageddon.”

While L.A. drivers prepare for catastrophe and stock up on canned goods, the 405 road closure illustrates one of the arguments presented in a recent article from Car and Driver magazine. “The State of the Union’s Roads: An Investigative Report” chronicles why so many of America’s roads are in poor condition – and what we should be doing about it.

“The interstates were designed to last 20 or 30 years,” the article explains, “but now some areas are pushing 50 years and handling far more traffic than their planners anticipated. But as we reach into our wallets, we run into our generation’s big dilemma: We’re nearly broke.” Highway revenues are down, repair costs are up and the federal government can’t afford the level of road investments it committed to in past years. While gas prices and time wasted in congestion are both soaring, more people are living in cities than ever before, which leads even Car and Driver to question the logic of doubling down on highways.
