The city’s 14th Street car ban is back.

A Manhattan judge ruled Tuesday that officials can move forward with a plan to speed up bus service on 14th Street by only letting buses, trucks with three or more axles, delivery vehicles and local residents access five blocks of the busy thoroughfare — rejecting a suit from local block associations worried about potential spillover traffic on side streets.

The city now plans to launch the car ban on Monday, officials said.

In her decision, Judge Eileen Rakower rejected the argument from plaintiffs that the project should have undergone an environmental review before its launch.

Rakower had previously issued a temporary restraining order on the plan, which was scheduled to launch July 1.

In siding with the city, Rakower said officials had taken the legally-required “hard look” at the project’s potential impacts, including on pedestrian safety, emissions, and travel times.

“I looked to see if they did their job,” she said, saying she concluded that officials had not “arbitrarily” or “capriciously” ignored data.

Lawyer Arthur Schwartz, who represents the block associations and is himself a resident of 12th Street, told the Post he was surprised by Rakower’s decision, and that his clients would likely want to proceed with an appeal.

“I have to assess whether the appellate court will do anything different than this judge did,” Schwartz said.

Transit activists, meanwhile, celebrated the decision.

“For the public good, people like this representing a small minority of people who want to keep cars and congestion in New York are not the way of the future,” said Melodie Bryant, 70, of Chelsea, who came to court to show support for the city’s case.

“New York needs fewer cars, better transit. Global warming requires that,” she added.
