Although touted by Governor Hochul and the MTA as a much needed transit link between Brooklyn and Queens, the realities of the proposed Interborough Express (IBX) prove to be quite the contrary and a high risk gamble.
A review of The New York Building Congress Report and the accompanying addendum published in June 2025 reveals that the Interborough Express is a $5.5 billion project in need of ridership along the route that does not currently exist unless and until neighborhoods along the route are altered in monumental ways.
To make the IBX viable, the opening paragraph of the addendum to The New York Building Congress Report states the following:
“…pairing the proposed IBX requires complementary housing policy. There must be enough population and job density near the stations, combined with supportive zoning and a walkable environment, to generate the ridership levels that justify the capital investment.” The addendum further states that this is a “critical priority.” This flies in the face of giving the impression that this light rail line is much needed. It actually requires a massive population shift to the train route at great expense to taxpayers, distress and upheaval to homeowners along the route who may be subjected to eminent domain. The environment would also be greatly impacted because much of the train route is lined with trees. The IBX would alter the character and density of communities and place stress on infrastructure.
The goal of community development along the train route may be beneficial in Brooklyn where all five community development projects cited in the MTA’s Report entitled, Interborough Express Feasibility Study and Alternatives Analysis Interim Report are situated. There is no such development need or desire for it on the Queens side.
The IBX is a tale of two boroughs. While the Brooklyn side of the route seeks economic development, the Queens side is a leafy green community of one- and two-family homes and residents like it that way.
This project appears to be a boondoggle for real estate developers. Building the IBX would be like The City of Yes on steroids, especially around the train stations. A scaled-down version of the IBX to accommodate the approximately 86,000 riders that currently travel within Brooklyn on a daily basis may be a good foundation for achieving the stated development goals along the route in that borough while making it more expedient to get around. If the IBX is contained to an area that is actively seeking development the MTA’s goal of viability may be more easily achieved as new housing and businesses are built in desired areas of the Brooklyn. All community development projects stated in the MTA’s reports are in Brooklyn.
The IBX has just entered the design phase which will take two years to complete. It may be in the best interests of communities along the route to put the brakes on this project pending a determination of its viability and benefits to each of the broughs. One size does not fit all.
