The federal government has publicly revised its estimate for how much the Hudson River tunnel might cost. This comes two weeks after New Jersey Governor Chris Christie cancelled the planned train tunnel citing federal estimates that the project could cost up to $5 billion over budget.

New Jersey Governor Chris Christie was expected to make his final decision on the Access to the Region’s Core (ARC)  train tunnel under the Hudson River Friday, but it’s increasingly unclear whether that will happen.

A top New Jersey Democrat says he's combed through the hundreds of pages that led Governor Chris Christie to dump the A.R.C. train tunnel under the Hudson River and found no justification for it.

(New York -- Matthew Schuerman, WNYC)  A top New Jersey Democrats says he's combed through the hundreds of pages that led Governor Chris Christie to dump the ARC train tunnel under the Hudson River and found no justification for it.

"The documents provided by the governor’s own administration fail to provide any justification for the governor’s claim of billions in cost overruns on the tunnel project," Assemblyman John Wisniewski, head of the Assembly's Transportation Committee said in a press release this afternoon. “That claim seems as though it was simply pulled out of thin air by the governor."

Wisniewski got roughly 400 pages of documents Wednesday from the governor's office through a freedom of information request. The Democrat said that three reports on cost estimates that were included state, "The overall project remains within budget," and repeat that the budget remains at $8.7 billion.

Christie, a Republican, canceled the tunnel two weeks ago, saying that internal reports pointed towards as much as $5 billion in cost overruns  and that he wasn't about to pass those costs on to New Jersey taxpayers.

Christie's office hasn't responded to a request for comment. Those wishing to pore through the documents themselves can find them on the assemblyman's web site.

UPDATE, 5:30 p.m. : Christie's office says the documents that Wisniewski reviewed are only the first batch of many that he will receive under his information request.

The LIRR will run just one-third the number of trains it usually does this week and large parts of the network will be out of service completely, to be replaced with subways or shuttle buses. The same disruptions will occur the following weekend.

A day after cancelling a new rail tunnel under the Hudson River, New Jersey Governor Chris Christie says he'll take another look at it. Christie promised a two-week review of several options that could salvage the tunnel after meeting with U.S. Transportation Secretary Ray LaHood. But the Republican governor insisted the project was "financially not viable" and likely to exceed its budget.

Speaking at a hospital ribbon-cutting in Newark, New Jersey Gov. Chris Christie, who is just returning from a multi-day midwest campaign swing with fellow Republicans, says he hasn't had a chance to meet with his staff or review the final numbers on the ARC commuter train tunnel from New Jersey to New York.

Despite widespread service cuts, the subway system has gotten mildly better. That's according to the Straphangers Campaign, which says the subway's gotten a little cleaner, a little more reliable, and its announcements are clearer this year compared to the year before.

If you think the subways are late, dirty and expensive now, imagine what it was like 25 years ago. In honor of the Straphangers' Campaign's latest report on the State of the Subways we took a look at one of the earliest documents the organization produced.

(New York -- Matthew Schuerman, WNYC) New Jersey never put up much of its own money towards the ARC Tunnel. And yet Governor Chris Christie seems poised to cancel the project because of money concerns.

Out of the tunnel’s $8.7 billion budget, New Jersey was contributing just $2.7 billion. Even that figure overstates the case, however. According to transportation officials, only $1.25 billion would come from New Jersey sources: the tolls collected by the NJ Turnpike Authority. Another billion and change comes from the federal government’s Congestion Mitigation and Air Quality Improvement Program (CMAQ), according to transportation officials.

If, or when, the tunnel’s canceled, New Jersey could divert the $1.25 billion in turnpike tolls easily—even to help out the state’s ailing Transportation Trust Fund. Christie will also be able to spend the CMAQ money on other road and bridge projects—although transportation sources say the money will have to be used in accordance with federal regulations, which would rule out its use for the trust fund.

The other $6 billion, contributed equally by the Port Authority and the Federal Transit Administration, is money slated specifically for the ARC Tunnel. Transportation sources say that Christie will have to sacrifice all of that money should he cancel the tunnel. However, presumably some Port Authority projects would take place in New Jersey.

Christie’s stated concern all along, however, was what New Jersey would do if the tunnel ended up costing more than $8.7 billion. According to one legislative source, the current agreement with the Federal Transit Administration calls for the Port Authority and the state of New Jersey to be jointly responsible.

The bottom line: Christie gets loses $6 billion in free money. But he gets to spend a different $2.25 billion on roads and bridges, all the while limiting his liability for cost overruns.

He also wouldn’t need to increase the gas tax to bail out the Transportation Trust Fund,thereby protecting his reputation as a fiscal conservative.
