Baltimore bridge collapse: a bridge engineer explains what happened, and what needs to change

ABC  

When the container ship MV Dali, 300 metres long and massing around 100,000 tonnes, lost power and slammed into one of the support piers of the Francis Scott Key Bridge in Baltimore, the bridge collapsed in moments. A 20th century bridge meets a 21st century ship The Francis Scott Key Bridge was built through the mid 1970s and opened in 1977. Once the massive ship had made it past both the dolphin and the fender, the pier — one of the bridge's four main supports — was simply incapable of resisting the impact. Today's cargo ships are much bigger than those of the 1970s, and it seems likely the Francis Scott Key Bridge was not designed with a collision like this in mind.
