This upcoming traffic apocalypse will be the end of Chris Christie

New Jersey Governor Chris Christie (R) is infamous as the guy whose underlings caused an epic traffic jam on the George Washington Bridge as part of some weird political punishment. In time, though, he will be known as the guy who caused the worst transportation snarl in the history of New York City.

I can't see how this traffic disaster will mean anything but the end of Christie's 2016 aspirations. The question for New Yorkers looking down the barrel of this sucker is whether it will be bad enough to break the hegemony of austerity in Congress.

So, what is happening? Let's wind the tape back to 2010. The Recovery Act was in full swing, and all manner of stuff was being built across the country with stimulus money. The biggest project of all was called Access to the Region's Core, a plan for a desperately needed new tunnel under the Hudson River and a new train station in Manhattan. There are only two other tunnels under the Hudson, both single-track and over 100 years old, both stuffed to capacity during rush hour, with demand only projected to grow.

The cost was projected at around $8 billion to $10 billion, with the federal government and the Port Authority picking up roughly three-quarters of the tab. Construction started in 2009, and hundreds of millions of dollars were spent on rights-of-way and initial work.

Then Christie unilaterally canceled the project, charging that costs were skyrocketing, that New Jersey would thus have to pay 70 percent of the bill, and that the feds were going to stick the state with any cost overruns.

He was lying through his teeth. A Government Accountability Office report later detailed that cost estimates had not increased, that New Jersey was only paying 14.4 percent, and the feds had offered to share the burden of any overruns. Instead, Christie swiped the money earmarked for the project and spent a bunch of it on New Jersey's highway fund, so he wouldn't have to raise the gas tax. (He's under investigation by the SEC and the Manhattan DA for that, among other things.)

It was an infuriatingly stupid decision. But Hurricane Sandy changed it from stupid to disastrous. During the storm surge both the tunnels under the Hudson were flooded with ocean water, and the deposited salts are eating away the 100-year-old metal and concrete. Therefore, according to a recent study, both tunnels will need a total top-to-bottom overhaul in the next few years. Shutting even one of them down would basically be traffic apocalypse:

In a blackly comedic coincidence, the canceled ARC tunnel would have come online in 2018, maybe just barely in time to take up the slack from one of the old ones being closed. Now those 300,000 or so displaced commuters are going to have to swim across the Hudson.

Anyway, according to the Times, Amtrak is going to work on the tunnels under the East River first, with no firm plans as to when they're going to have to shut down the Hudson tunnels. They have a plan for another tunnel called the Gateway, but no way to pay for it as of yet.

And that brings us to Congress. The prospects for action at the federal level are nearly hopeless, but it's worth noting that if they wanted to, Congress could solve this problem — just by appropriating some money for a new tunnel. Probably the best chance of that will be after the old tunnels are shut down and there's a massive traffic jam from Newark to Long Island.

But in any case, Christie's boneheaded posturing is at least yet another demonstration of the failure of austerity. Turns out not spending money doesn't make crippling infrastructure needs disappear. It just postpones the day of reckoning, and raises the chances of expensive catastrophic failure.
