Interborough Express (IBX)
The Interborough Express is a transformative rapid transit project that would connect currently underserved areas of Brooklyn and Queens. It would substantially reduce travel time between the two boroughs, reduce congestion, and expand economic opportunities for people who work in the surrounding neighborhoods.
The project would be built along the existing Bay Ridge Connect and CSX-owned Fremont Secondary, a 14-mile freight line extending from Bay Ridge Brooklyn to Jackson Heights, Queens. It would create new transit options for nearly 900,000 residents along the route and 260,000 people who work in Brooklyn and Queens. It would connect with up to 17 different subway lines and the Long Island Rail Road (LIRR), providing service to underserved locations where more than one third of residents live below the federal poverty line. It would bring much-needed transit service to underserved areas like East Flatbush, Maspeth, and Canarsie. The IBX could help reduce car commutes while redirecting outer borough trips from overburdened Manhattan-bound subway lines. The project is guided by six key needs:
- Improve transit connections to community job centers
- Cost-effectively meet needs of transit and freight systems within the dedicated right-of-way
- Support economic growth in local communities
- Preserve freight corridor for current and future needs
- Reduce roadway traffic by increasing number of residents riding public transit
- Connect to and between subway lines to provide better travel options
Environmental review process ongoing
Environmental review and interim report
Gov Kathy Hochul directed the MTA to begin the environmental review process for the Interborough Express and to identify the best mode of transit for the project (heavy rail, light rail, or bus rapid transit). Interim Report released.
MTA initiates feasibility study
RPA’s Four Regional Plan
The Regional Plan Association’s (RPA’s) Four Regional Plan envisions the Bay Ridge Branch as part of its flagship Triboro RX subway line, connecting Brooklyn, Queens, and the Bronx. (Current IBX study doesn’t propose extending IBX to Bronx due to lack of capacity across Hell Gate Bridge.)
