City officials have intentionally ground Midtown to a halt with the hidden purpose of making drivers so miserable that they leave their cars at home and turn to mass transit or bicycles, high-level sources told The Post.

Today's gridlock is the result of an effort by the Bloomberg and de Blasio administrations over more than a decade of redesigning streets and ramping up police efforts, the sources said.

"The traffic is being engineered," a former top NYPD official told The Post, explaining a long-term plan that began under Mayor Mike Bloomberg and hasn't slowed with Mayor de Blasio.

"The city streets are being engineered to create traffic congestion, to slow traffic down, to favor bikers and pedestrians," the former official said.

"There's a reduction in capacity through the introduction of bike lanes and streets and lanes being closed down."
