Bay Crossing Study Tier 1 NEPA Concludes

FHWA Officially Approves Corridor 7, the Corridor Containing the Bay Bridge,

as the Selected Corridor Alternative


The combined Final Environmental Impact Statement (FEIS) and Record of Decision (ROD) for the Chesapeake Bay Crossing Study: Tier 1 National Environmental Policy Act (NEPA) has been published and is available for review at and starting April 22, at several local libraries. The combined FEIS/ROD has been prepared pursuant to NEPA and has been approved by the Federal Highway Administration (FHWA).  The FHWA identified Corridor 7, the corridor containing the Bay Bridge, as the Selected Corridor Alternative. The approval of the FEIS/ROD marks completion of the Tier 1 NEPA Study.

The Maryland Transportation Authority (MDTA) and FHWA followed a well-established tiered NEPA process that provides a systematic approach for advancing potential transportation improvements. The federal NEPA process applies to all projects potentially receiving federal funding or approval.

The Bay Crossing Study Tier 1 NEPA evaluated a range of alternatives, including a no-build alternative, four modal and operational alternatives, and 14 corridor alternatives, to provide expanded traffic capacity and additional access across the Chesapeake Bay to improve mobility, travel reliability and safety at the existing Bay Bridge, while considering financial viability and environmental responsibility.

The combined FEIS/ROD focuses on updates to the February 2021 Draft Environmental Impact Statement (DEIS) that was available for review and comment from February 23 through May 17, 2021. The DEIS content and analysis remain valid except where updated information is noted in the FEIS. The FEIS provides summaries of the more than 850 agency and public comments received and responds to substantive comments.

The FEIS also details the rationale and information supporting the selection of Corridor 7 as the Preferred Corridor Alternative (PCA). Through an alternative screening process derived from the Study’s purpose and need, including an extensive agency and public review and comment process, the combined FEIS/ROD concluded that the corridor containing the existing Bay Bridge – Corridor 7 – would have the most positive impact on reducing traffic at the Bay Bridge when compared to other alternatives and would improve access and mobility in this essential transportation corridor. The ROD officially documents Corridor 7 as the Selected Corridor Alternative.

Any next steps would require additional environmental review through a Tier 2 NEPA Study. A Tier 2 NEPA Study would identify specific alignment alternatives within the two-mile-wide Selected Corridor Alternative identified during Tier 1.
