The bridge collapse is a stark reminder of the vulnerability of the nation’s aging infrastructure and the importance of supply chain resilience. Supply chain resilience is the ability of a supply chain to withstand and recover from disruptions, such as natural disasters, accidents, cyberattacks, or pandemics. A resilient supply chain can maintain its functionality and performance, minimize losses, and adapt to changing conditions. Supply chain resilience is crucial for ensuring the continuity of business operations, the delivery of essential goods and services, and the protection of public safety and national security.

The collapse had several immediate and long-term consequences for the region. The most obvious impact was the disruption of traffic and transportation. The bridge was a vital link for commuters, tourists, and truck drivers, who had to find alternative routes or modes of travel. The bridge also carried several utility lines, such as water, gas, and fiber optic cables, which were severed or damaged by the collapse. The bridge’s closure also affected the operations of the Port of Baltimore, which is one of the busiest and most important ports on the East Coast. The port handles about 11 million tons of cargo per year, including automobiles, containers, coal, and farm products. The port relies on the bridge to connect the rail network and the interstate highway system, which are essential for moving goods to and from the port. The port’s closure could have significant economic and environmental impacts, as well as implications for national security and defense.  The neighboring port in Norfolk Virginia and other east coast ports like New York City can absorb the additional traffic without many complications or delays, but this incident provides an opportunity to discuss the importance of supply chain resilience.

Supply chain resilience is a multidimensional concept that encompasses various aspects of a supply chain’s ability to cope with disruptions. According to a widely cited framework by Christopher and Peck from “Building the Resilient Supply Chain” (2004), supply chain resilience consists of four dimensions: robustness, agility, redundancy, and flexibility. These dimensions are briefly defined and illustrated below.

These dimensions are not mutually exclusive or exhaustive, but rather complementary and interrelated. A resilient supply chain should have a balanced and integrated combination of these dimensions, depending on the nature, frequency, and severity of the disruptions it faces. A resilient supply chain should also have a proactive and learning orientation, meaning that it should anticipate and prepare for potential disruptions, as well as learn from and improve after experiencing disruptions.

The closure of the Port of Baltimore due to the bridge collapse has significant impacts on the supply chains of various industries and sectors that depend on the port for importing and exporting goods. Some of the major industries and sectors that are affected by the port closure are:

The impacts of the port closure on these and other industries and sectors are not only limited to the local or regional level, but also have ripple effects across the national and global supply chains. The port closure affects the availability, quality, and cost of goods and services, as well as the competitiveness, productivity, and innovation of businesses and industries. The port closure also affects the social and environmental aspects of supply chains, such as employment, safety, health, and sustainability. The port closure also exposes the vulnerabilities and interdependencies of supply chains, as well as the need for resilience and collaboration among supply chain stakeholders.

The Francis Scott Key Bridge collapse and the Baltimore port closure are examples of the types of disruptions that supply chains face in an increasingly complex and uncertain world. These disruptions pose significant challenges and risks for supply chain performance and survival, but also offer opportunities and incentives for supply chain improvement and innovation. To enhance supply chain resilience and cope with future disruptions, some of the best practices and recommendations are:

By following these best practices and recommendations, supply chains can enhance their resilience and cope with future disruptions. Supply chain resilience is not only a defensive and reactive capability, but also a strategic and proactive advantage. A resilient supply chain can not only survive, but also thrive, in an uncertain and dynamic world.
