An upcoming toll on driving into Manhattan’s busiest streets aims to cut the number of pollutant-spewing vehicles and clean the air.

But an MTA study on the effects of the toll concludes that Bronx residents would get the brunt of the bad — more congestion and polluted air.

In one possible tolling scenario, nearly 4,000 additional vehicles, including over 700 trucks a day, would drive onto the Cross Bronx Expressway at Macombs Road to avoid paying the toll to enter Manhattan below 60th Street.

It’s turning supporters of congestion pricing, like Rep. Ritchie Torres, a Bronx Democrat, into critics.

“The cruel irony of congestion pricing is that it would lead to more congestion in the Bronx,” Torres said. “That was the opposite of what we were promised.”

“We should ask ourselves a simple question: is it fair to create less congestion and emissions and pollution in Manhattan, at the cost of creating more congestion and emissions and pollution in the Bronx?” Torres added.

The Cross Bronx Expressway is already heavily congested and the traffic is a source of poor air quality in the South Bronx.

“The people of the Bronx, the children of the Bronx are struggling to breathe amid the highest rates of asthma,” Torres said.

The study shows the Bronx would get increases in pollutants

But the study finds the extra traffic would have “no adverse effects” with “no mitigation needed.”

Despite this, the head of the MTA says the extra traffic in the Bronx will be addressed.

“There may be localized impacts. The idea of the study is to mitigate those and I’m confident that the people who make the decision about how it actually is done will take that into consideration and address the Cross Bronx issue,” MTA Chair Janno Lieber said.

Staten Island would also get more traffic according to the study. Opposition to congestion pricing already abounds in the borough where some call it an unfair tax on car owners who pay to drive in and out of the borough over the Verrazano Bridge.

To now hit them over the head with another fee that could be as high as 23 dollars to enter another borough in the city in which they live is absolutely unacceptable," Rep. Nicole Malliotakis, a Staten Island Republican, said at a news conference Monday.

Supporters of congestion pricing argue the entire region will benefit from a reduction in traffic coming into Manhattan’s congestion zone by as much as 20%.

The MTA is holding hearings this month for the public to weigh in on a first in the nation toll the MTA expects to be in place by early 2024.
