Bridge Safety Alert: Johns Hopkins Team Mobilizes Post-Baltimore Tragedy

In the wake of the tragic collapse of the Francis Scott Key Bridge, a team of researchers from Johns Hopkins University in Baltimore has embarked on a vital mission: assessing the safety of the nation's bridges to prevent future disasters. Comprising students and faculty members, this dedicated team is focusing on large bridges located near major ports of entry, as announced in a press release on Wednesday.

We need to know now, not five or 10 years from now, whether there is an outsize risk to bridges across the country," emphasized team leader Michael Shields, an engineer specializing in risk assessment. "The Key Bridge collapse was a wake-up call.

The sudden crumbling of the steel span, triggered by the container ship Dali's loss of power and subsequent collision with one of its supporting columns shortly after departing Baltimore’s port on March 26, claimed the lives of six roadwork crew members. Experts and officials have highlighted various factors contributing to the bridge's vulnerability, including insufficient pier protection that remained unchanged for decades despite the increasing size and presence of cargo ships.

Clearly the risk to the Key Bridge was very different in 2024 than it was in 1977 when the bridge opened," Shields remarked. "But we don’t currently understand that risk.

To gauge the vulnerability of other bridges, the researchers will construct models to assess the likelihood of a ship deviating from its course and causing a catastrophe in or around major ports. The hope is that policymakers will utilize the findings of this assessment to guide future investment decisions and prioritize safety upgrades in infrastructure.

We're witnessing the challenges posed by the exponential growth of mega freight ships and the surge in global shipping traffic," explained team member Rachel Sangree, a structural engineer and former bridge inspector. "Many of our bridges simply weren’t built to withstand the pressures of today’s maritime landscape.

Meanwhile, the National Transportation Safety Board, a federal oversight agency investigating the collapse, noted in its preliminary report that the Dali bypassed a protective concrete piling—also known as a dolphin—before bringing down the bridge.

As officials delve into the aftermath of the Francis Scott Key Bridge collapse, their scrutiny extends beyond immediate repercussions. They're now evaluating whether pier protection enhancements are necessary for other Maryland bridges, notably the Chesapeake Bay Bridge near Annapolis, a vital link connecting Baltimore and Washington to Maryland’s Eastern Shore. However, such upgrades come with hefty price tags.

Testifying before a congressional committee, board Chair Jennifer Homendy stressed the importance of conducting risk assessments on major bridges nationwide, emphasizing that this catastrophe could happen in any district.

In parallel, the FBI has initiated a criminal investigation into the events leading to the Key Bridge collapse. Initial findings suggest that while two tugboats initially guided the Dali out of Baltimore’s port, they disengaged upon entry into the main shipping channel, following standard procedure. Experts ponder whether a prolonged tugboat escort could have averted the ship's erratic trajectory.

Yet, opinions diverge on whether the collapse was preventable. U.S. Transportation Secretary Pete Buttigieg, reflecting on the matter during a visit to Baltimore, highlighted ongoing debates among engineers regarding the effectiveness of various safety measures.

Originally erected in the 1970s, the Key Bridge served as a critical link between Baltimore's industrial maritime communities, embodying the city’s rich working-class heritage and bustling port. Its collapse paralyzed maritime traffic for weeks and disrupted East Coast trucking routes. Fortunately, efforts to salvage the Dali and restore port operations are progressing, aiming for full reopening by June 10.

Plans for bridge replacement are already underway, with an anticipated completion by 2028 and a staggering price tag nearing $2 billion. Funding from federal sources, insurance claims, and other reimbursements will fuel the extensive rebuild and recovery endeavors.

A recent report from the Maryland Chamber of Commerce underscored the far-reaching economic consequences of the collapse, advocating for heightened investments in transportation infrastructure to prevent future calamities.
