TRENTON, N.J. (CBS) -- Could South Jersey transportation projects end up benefitting from New Jersey Governor Chris Christie's cancellation of a planned new train tunnel under the Hudson River?

The governor announced Wednesday morning that he's killing the tunnel project because taxpayers cannot afford billions in cost overruns.

"We do not have the money," he said at a morning press conference. The project could end up costing $6 billion more than the estimate of nearly $9 billion.

What the governor has not said is what happens to the state money that's committed to the tunnel. The governor's move could potentially free up money for other stalled projects, like a proposed train line from Camden to Glassboro.

"I have no idea what we're going to do," said Governor Christie when asked about the effect of the cancellation on other projects and New Jersey's nearly-depleted transportation trust fund.

Eyewitness News asked the governor specifically about the proposed Gloucester County light rail line. In the past, the Governor has said he supports it, but he's not sure the state can honor a $500 million commitment made by the Corzine Administration. The project is expected to cost $1.6 billion.

"I don't have any idea at the moment whether this would free up money to do that [the Gloucester County Line] or not and where that would be in the priority list of projects," the governor said.
