Introduction

The Metropolitan Transportation Authority (MTA) has initiated the environmental review process for the Interborough Express (IBX) passenger-rail system, as required by New York state environmental law. This marks a significant milestone for the IBX project, following its entry into preliminary engineering and design in August.

Environmental Review

The environmental review process is designed to evaluate both the potential environmental benefits and the impacts of the IBX project, according to MTA officials. This review is a crucial step in the project’s development.

Project Scope

The IBX project is planned to establish a rail service linking underserved areas within Brooklyn and Queens to the existing subway, bus network, and the MTA Long Island Rail Road. The project aims to reduce travel times between the two boroughs, with an estimated end-to-end travel time of 32 minutes. This service will operate along a 14-mile freight line currently owned by the MTA and CSX.

Engineering and Design

In August, the MTA Board approved the selection of a joint venture comprising Jacobs and HDR. This joint venture will be responsible for overseeing the design and engineering of the light-rail system for the IBX project.
