MDTA Recommends Building Two New Bay Bridge Spans, Demolishing Existing Structure

The Maryland Transportation Authority (MDTA) is proposing a significant transformation of the Chesapeake Bay crossing, with a recommended preferred alternative that includes the construction of two new, four-lane bridge spans and the removal of the current Bay Bridge spans. This recommendation, part of the Chesapeake Bay Crossing Study’s Tier 2 National Environmental Policy Act process, will be presented to the MDTA Board for a vote on December 18. The proposed plan aims to enhance travel experience, increase capacity, and improve safety along the US 50/301 corridor.

Alternative C, the staff’s chosen option, involves building two new bridge spans, each accommodating four lanes of traffic and featuring full shoulders. This addition is intended to bolster safety, increase reliability, and provide greater mobility for travelers. Simultaneously, the existing Bay Bridge spans would be removed. This demolition would address current roadway deficiencies, such as narrow lanes and the absence of shoulders, thereby eliminating the need for disruptive rehabilitation projects and associated traffic delays. Furthermore, the removal would increase navigational clearance to match that of the new Key Bridge, potentially facilitating access for larger vessels to the Port of Baltimore. To manage the transition to the new spans, US 50/301 would be widened to eight lanes, four in each direction, from west of Oceanic Drive to east of Cox Creek. The recommendation also includes financial commitments for transit-related improvements and an optional shared-use path for bicycles and pedestrians, the inclusion of which will be subject to further evaluation by the MDTA.

The MDTA’s recommendation is based on extensive engineering reviews, environmental studies, public feedback, and collaboration with local, state, and federal partners. Officials state that Alternative C is considered the most cost-effective among the proposed build alternatives, with the least impact on natural, socio-economic, and cultural resources. The project is projected to bring an estimated $17 to $23 billion into the local economy and create between 61,300 and 75,600 jobs, with a significant portion, approximately 76%, directly involving construction workers.

This proposed plan will undergo further public and agency review as part of the ongoing National Environmental Policy Act process. Both the general public and relevant regulatory agencies will have the opportunity to submit comments on the recommendation and the Draft Environmental Impact Statement, with public hearings anticipated in February 2026. Currently, the Federal Highway Administration and other resource and regulatory agencies have not yet formally concurred on a preferred alternative. Following the public comment period, state and federal agencies, including the U.S. Army Corps of Engineers and the Maryland Department of the Environment, will be invited to concur on the preferred alternative in Spring 2026. A final decision is expected in November 2026, when the Federal Highway Administration, in conjunction with the MDTA, will issue a combined Final Environmental Impact Statement and Record of Decision.

The Bay Crossing Study: Tier 2 National Environmental Policy Act, initiated in June 2022, aims to address current and future transportation needs across the Chesapeake Bay and at its approaches. The study team has analyzed numerous preliminary alternatives, narrowing them down to seven for public presentation in December 2024. Pending funding, design procurement is slated to begin after the Final Environmental Impact Statement and Record of Decision are finalized. Design is anticipated to start in Spring 2028, with construction potentially commencing in Summer 2032. Details regarding the availability of the Draft Environmental Impact Statement and public hearing schedules will be announced on http://www.baycrossingstudy.com. The MDTA, which finances its operations through toll revenue without reliance on state tax dollars, oversees eight state toll facilities.
