New York City and the Metropolitan Transportation Authority on Monday asked a judge to block the Trump administration from eliminating the city’s congestion pricing program.

Lawyers for the city’s transportation department and the MTA requested the judge issue an order to block Transportation Secretary Sean Duffy’s plans to kill the program and his threat to withhold federal government approvals for other projects and potentially billions in funding.

New York State also asked for a preliminary injunction to block the federal government from blocking the program.

Travel times to enter Manhattan have dramatically improved and traffic was reduced by 12% last month, while hotel stays, retail spending and pedestrian traffic have all increased, the city said.

“Stopping the program would also mean a return to the crippling congestion that has long plagued Manhattan,” the MTA and the city wrote.

New York Gov. Kathy Hochul, a Democrat, has said funds raised from the program would support $15 billion in debt financing for mass transit capital improvements.

Last month, Duffy told Hochul that the Department of Transportation may withhold environmental approvals or project funding if the state does not eliminate congestion pricing by late May.

The department approved the congestion program in November under former President Joe Biden’s administration. DOT approval is required because it involves tolls on federal highways.

Duffy and other critics of the program argue that it pulls money from working people and leaves drivers without a free highway option.
