President Donald Trump's budget plan sent a clear message to lawmakers in New Jersey and New York: If you want a new rail tunnel under the Hudson River, you can pay for it.

The president's proposed 2020 budget, rolled out Monday, includes no funding for the $13.5 billion project and cuts the amount of funding for Amtrak's Northeast Corridor that could be used to start it.

A deal last month to keep the government open through Sept. 30 appropriated $650 million to the Northeast Corridor. Trump's budget cuts that amount to $350 million.

In a conference call with reporters, Deputy Transportation Secretary Jeffrey Rosen said the project was a local responsibility, and that the two states would have to pony up.

Rosen said there was "no discernible path forward" for a series of projects known as the Gateway Program, which includes the Hudson tunnel, a $1.7 billion replacement for the Portal Bridge in the Meadowlands, and other improvements between Newark Penn Station and New York Penn Station.

"There is no reason for the federal government to have those projects jump the line and receive massive federal subsidies for projects that presently are ineligible and which lack realistic plans and commitments," he said.

Lawmakers from New York and New Jersey have said the Obama administration had agreed to pay for half the cost of the new bridge and tunnel, but that Trump walked it back. The project's supporters argue that they're federal assets that are critical pieces of infrastructure in the region's economy and merit federal support. Amtrak owns both.

TUNNEL TOUR:Murphy tours deteriorating Amtrak Hudson River tunnel in push for fix

A BIG HIT:Hudson rail tunnel shutdown could hit North Jersey property values, tax revenues

FARE DEAL:With a promise not to hike NJ Transit fares, is Murphy delaying the inevitable?

More than 200,000 Amtrak and NJ Transit riders use the 109-year-old tunnel daily. It was severely damaged by seawater flooding in Superstorm Sandy in 2012, and experts warn that its concrete lining is rapidly disintegrating. It could take a decade to build a replacement.

A recent report from the Regional Plan Association concluded that a tunnel failure could cost the region as much as $22 billion in property values over four years, and counties in New Jersey could lose hundreds of millions of dollars in property tax revenue they count on to pay for schools, police and fire departments, and other municipal services.

That's what the Gateway project's supporters call the "doomsday" scenario. Reps. Josh Gottheimer, D-Wyckoff, and Peter King, R-N.Y., want the federal government to explain what would happen should the tunnel fail.

"We'd like to see their contingency plan," Gottheimer said Monday at New York Penn Station. "We'd like to see what their plan is."

King, a member of the House Homeland Security Committee, said when commercial aviation was suspended in the immediate aftermath of the Sept. 11, 2001, terrorist attacks, the Hudson rail tunnel was the region's link to other major cities.

"This is a matter of national security," he said Monday at Penn Station. "Every day we wait is a day closer to a terrible disaster."

Gottheimer and King have introduced legislation to require the U.S. Department of Transportation to quantify the economic impact of a tunnel failure on the region and the nation. If it is enacted, the department would have to produce a report within 60 days.

"They're going to have a lot to answer for," Gottheimer said.

On Tuesday, Sens. Bob Menendez and Cory Booker of New Jersey, with Sens. Charles Schumer and Kirsten Gillibrand of New York, will meet with Gateway Program leaders in Washington to figure out how to move forward with the Portal Bridge project.

Portal, a swing bridge built in 1910, has a tendency to get stuck whenever it's opened for waterborne vessels. That delays riders on both Amtrak and NJ Transit.
