Film Lens

Why Bridges Collapse
The documentary examines the collapse of the Polcevera Bridge in Genoa, Italy, which occurred on August 14, 2018, resulting in the deaths of 43 people. It discusses the bridge's history as a landmark and its sudden failure, which left no warning signs. The film raises questions about accountability and the safety of aging infrastructure, noting that over 60 bridges have collapsed globally in the last decade and that more than 47,000 bridges in the United States are classified as structurally deficient. It also covers advancements in engineering that aim to prevent future collapses. The documentary shows new techniques and regulations that help ensure the safety of bridges, such as calculating the strength of gusset plates and preventing cavities in concrete grout. By learning from past failures, engineers hope to improve the safety of bridge designs for the future.
