The Unforeseen Positive Externalities of Congestion Pricing

Traffic moves through the Bowery in Lower Manhattan, within the zone covered by New York City’s Central Business District congestion pricing program.

When New York City’s first-ever urban congestion pricing program—the Central Business District Tolling Program—received final federal approval in June 2023, it ignited fierce political hostility. Yet the program now delivers many of the benefits its designers promised, shifting the debate from whether congestion pricing works to how policymakers should adjust administration. Even before implementation, neighboring states and local officials filed legal challenges seeking to block the toll. In 2023, sitting New Jersey Senator Bob Menendez called the proposal a “brazen money grab,” and then-Governor Phil Murphy warned, “We’ll bear the burdens of congestion pricing while New York City gets the benefits, and that’s not fair.”

In May 2025, shortly after the program’s implementation in January, US Secretary of Transportation Sean Duffy argued that the fee unfairly targeted working-class commuters. Even before President Donald Trump took office in January 2025, Republican lawmakers urged him to dismantle the program. In February 2025, the Trump administration moved to terminate federal approval for the program, reversing the authorization granted by the Federal Highway Administration; shortly thereafter, Trump took to Truth Social to announce, “CONGESTION PRICING IS DEAD. Manhattan, and all of New York, is SAVED. LONG LIVE THE KING!”

Critics warned of cascading consequences. They argued traffic would increase in Staten Island, the Bronx, and northern New Jersey as drivers sought to avoid the charge. Commuters would simply detour through surrounding neighborhoods, shifting congestion rather than reducing it. Working-class residents, unable to pay the toll, would shoulder longer commutes or reduced access to jobs. The fee would dampen commercial activity in the congestion zone, particularly for small businesses reliant on regional customers. The program appeared to be broadly unpopular across constituencies and threatened not only drivers but the broader regional economy.

More than a year into the program, the evidence tells a different story: congestion pricing has delivered on its promises. Furthermore, the feared collateral damage to suburban drivers and low-income New Yorkers has not materialized; in fact, both groups are among those receiving spillover benefits. Notably, much of the time savings for drivers has accrued to travelers outside the toll zone entirely—including commuters traveling across Northern New Jersey, the same region whose leaders once filed suit to block the plan. 

As for concerns about low-income New Yorkers, the data tell a similar story. For every working New Yorker in poverty who regularly pays the congestion charge, roughly 50 benefit from the mandated investment of congestion revenues into transit upgrades. Fewer than 3% of low-income outer-borough residents commute into the tolling zone by car, and the program includes a built-in low-income discount that cuts the fee by 50% for eligible drivers. Additional positive externalities include reduced traffic noise and measurable improvements in air quality across the central business district. Public policy rarely produces reforms that generate measurable gains without corresponding measurable losses. Congestion pricing has come remarkably close. Yet President Trump has not backed down on his effort to dismantle it. Earlier this month, the administration assigned Deputy Assistant US Attorney General Eric Hamilton—a senior Justice Department official handling some of the White House’s most politically consequential cases—to lead the federal effort to rescind approval of the program. Its demise, it seems, remains a priority for the president despite its continued and demonstrable success.

However, the program’s early success also raises a structural question: whether congestion pricing should remain a politically negotiated toll or evolve into a system that automatically adjusts to traffic conditions. Under New York’s current model, toll levels remain largely fixed rather than adjusting automatically to changes in traffic speed, leaving improvements dependent on a static pricing structure rather than a responsive one.

If New York intends for congestion pricing to endure, it should eventually move toward a more explicitly dynamic model—one in which toll rates adjust automatically in response to traffic speeds rather than through ad hoc political negotiation. Singapore offers the clearest example. The Land Transport Authority, a centralized civil service agency that reviews traffic speeds quarterly and adjusts tolls according to preset benchmarks, administers congestion pricing. If speeds fall below target levels, prices rise; if congestion eases, prices decline. Pricing changes are tied directly to traffic metrics and are wholly administrative.

It would be naïve to imagine that New York could fully replicate Singapore’s political insulation in the administration of congestion pricing. Overlapping jurisdictions, federal oversight, and election cycles make complete technocratic detachment in this context unrealistic—especially considering the interstate lawsuits and federal interventions that have already defined the program’s early years.  Full insulation is neither assumed nor required for the program to endure. Whether New York can reduce the volatility, however, remains an open question. A more institutionalized, data-triggered adjustment mechanism would make future rate changes less vulnerable to electoral timing and partisan framing. 

Congestion pricing risks remaining a campaign issue rather than a transportation policy. Its future will depend less on whether traffic declines than on whether elected officials allow the system to operate long enough to validate its results.
