Proposed station
Connecting subway services

The Interborough Express (IBX) is a proposed 14-mile (23 km) 24/7 light metro line in New York City. As proposed, the line would operate on dedicated tracks within the existing right-of-way from the Bay Ridge Branch and Fremont Secondary to connect the Brooklyn Army Terminal in Bay Ridge, Brooklyn, with the neighborhood of Jackson Heights, Queens. As of 2025, the Metropolitan Transportation Authority (MTA) estimated that the project would be operational in the early 2030s.
