Maryland Transportation Authority Outlines Plans for Enhanced Bridge Protection and Addresses Key Bridge Collapse

The Maryland Transportation Authority (MDTA) has provided an update on its ongoing efforts following the Francis Scott Key Bridge collapse and the associated loss of life, asserting that the incident was solely the fault of the container ship DALI and its operators. In parallel, the MDTA is advancing plans for enhanced protection systems on the William Preston Lane Jr. Memorial (Bay) Bridge, a project valued at approximately $177 million. The MDTA is also reviewing the final report and recommendations from the National Transportation Safety Board regarding the Key Bridge collapse.

Regarding the Francis Scott Key Bridge incident, the MDTA maintains that the bridge itself was constructed in compliance with federal government approvals and permits. The authority has stated that the design process for the replacement bridge is progressing, and it will incorporate a rigid fender pier protection system designed to meet current American Association of State Highway and Transportation Officials (AASHTO) standards.

The MDTA has emphasized that the safety of Maryland’s highways and bridges remains a paramount concern. The Bay Bridge, inspected annually for over three decades, is currently deemed safe and in satisfactory condition. Over the past ten years, Maryland has allocated more than $175 million towards improving the safety and security infrastructure of the Bay Bridge. Although the existing pier protection and design of the Bay Bridge meet federal permit requirements, the MDTA is actively pursuing enhanced physical protection measures. These steps are being taken in response to increasing vessel sizes, weights, and speeds, noting that maritime regulations have not kept pace with these developments.

In spring 2024, the MDTA initiated a study to evaluate and assess bridge protection enhancements. This study phase, which cost $600,000, was conducted by Moffatt & Nichol, a firm recognized for its expertise in vessel collision design for bridges. With the study phase now concluded, the MDTA is moving forward with the design for construction of these upgraded protections at the Bay Bridge. To facilitate this, the MDTA hosted an industry forum on October 20. At this event, MDTA representatives detailed the anticipated design-build process and engaged with potential contractors, consultants, and subcontractors specializing in heavy marine construction. Industry stakeholders were also informed about the upcoming request for proposals, expected to be released in winter 2025.

The MDTA is undertaking this protection enhancement project concurrently with its broader Bay Crossing Study, which is examining the potential replacement of the existing Bay Bridge spans. The authority has stated its commitment to ensuring that the current protection project does not impede or preclude any future decisions or projects related to replacing the existing bridge spans.
