Designers and engineers can create bridges that also serve as monumental artworks and civic landmarks. Why do new spans in the US so often fall short?
When the Francis Scott Key Bridge collapsed after being struck by a massive container ship early in the morning on March 26, six highway workers were killed, a segment of the Baltimore Beltway was severed, the Port of Baltimore was largely shut down for two months — and the city lost an important piece of its identity.
Before its destruction made it famous, the Key Bridge was not really a landmark like San Francisco’s Golden Gate Bridge or other charismatic spans that serve as symbols for their host cities. Built in 1977, it was a more utilitarian structure, with brawny trusswork that evoked the city’s industrial past, and an important job to do: It could carry the fuel-hauling tanker trucks that are prohibited from traveling through two nearby tunnels. Its visibility at the mouth of Baltimore’s harbor marked it as a prominent link between the modest communities that line the blue-collar waterfront and the glass apartment and office towers that now define the downtown skyline.
