Tappan Zee Bridge/I-287 Environmental Review

About the Study

This Web site is part of a comprehensive outreach effort. We are committed to maintaining an open and transparent process of information sharing and public involvement in this major study of the I-287 Corridor, including the Tappan Zee Bridge, to help determine how to improve mobility between Suffern and Port Chester.

Congestion along the I-287 Corridor continues to worsen. While the Tappan Zee Bridge is safe, due in large part to a rigorous program of maintenance and inspection, the structural needs of the bridge must be addressed.

The challenges of the structure and the corridor have created an opportunity to examine the mobility needs of the region comprehensively. We welcome the input of all stakeholders as we seek to discover the best way to assure a safe and effective transportation infrastructure for the future.

The aim of the Tappan Zee Bridge/I-287 Corridor Project is to:

    • Resolve the structural needs of the Tappan Zee Bridge;
    • Identify a potential transit link for the region; and
    • Determine the safest, most efficient, environmentally sound,
      and responsible way to address the transportation needs of
      the Tappan Zee Bridge/I-287 Corridor for the next century.

This project is being conducted by the New York State Department of Transportation, the New York State Thruway Authority and MTA Metro-North Railroad, under the supervision of the Federal Highway Administration and the Federal Transit Administration, the federal co-leads for the National Environmental Policy Act (NEPA) process.
