Governor Andrew Cuomo says there's an "urgent need" to replace the 105-year-old rail tunnel in the Hudson River that links New York and New Jersey, but he says a loan from the federal government to help build it isn't enough.

In an interview with NY1, the governor said the prospects for a new tunnel are "not especially bright" if New York, New Jersey and the Port Authority shoulder what he described as a "massive financial burden."

The estimated cost of a new tunnel serving riders on Amtrak and New Jersey Transit ranges from $10 to $14 billion.

In a letter to Transportation Secretary Anthony Foxx, Cuomo says the federal government should foot the bill for "an Amtrak asset that has fallen into disrepair through lack of Amtrak investment over decades."
