The cameras that will charge motorists to drive into Manhattan below 60th Street have gone up on the Upper West Side.

But across the Hudson River, New Jersey officials are trying to put a stop to congestion pricing with a federal lawsuit filed Friday — months before these cameras can toll a single vehicle starting in the spring.

“New York’s congestion tax plan in my view is a brazen money grab,” Sen. Bob Menendez, a New Jersey Democrat, said. “It’s highway robbery.”

New Jersey state filed the suit against the U.S. Department of Transportation and the Federal Highway Administration Friday.

The MTA is not a party in the suit. It calls the federal approval of congestion pricing “a rubber stamp” in violation of federal environmental laws, by failing to require a more rigorous study known as an Environmental Impact Statement.

The lawsuit says federal officials “disregarded the significant impacts to new jersey’s environment,” like the expected increase in air pollution in Bergen County.

“Unfortunately, New York’s proposal will prompt toll shopping where more drivers seek circuitous routes to avoid paying the highest tolls resulting in more traffic and more pollution in certain areas,” New Jersey Gov. Phil Murphy, a Democrat, said.

After announcing the lawsuit, Murphy suggested to reporters that there could be a way to earn his support for congestion pricing.

“Is there a deal to be done here? I don’t know. I hope so,” he said. “But we feel strongly that the environmental interests and consequences were not properly factored into the federal government’s — basically — go ahead.”

MTA and New York officials have defended the plan as a way to clean the air, cut down on congestion in Manhattan’s busiest streets and provide mass transit with billions of dollars.

Gov. Kathy Hochul said that New Jersey residents who commute into Manhattan would benefit when they take public transportation in New York.

“It’s making sure we’re making the investments, to make sure that it endures and is not compromised going forward,” Hochul, a Democrat, said. “So, it’s for everyone, but also, it’s going to mean cleaner air, less congestion.”

A spokeswoman for the Federal Highway Administration declined to comment on pending litigation.

New Jersey is asking the court to scrap the federal government’s approval and require a full environmental study.  

Meanwhile, an MTA spokesman said the lawsuit is baseless and that officials are confident the federal approval will stand up to scrutiny.
