The recent collapse of the Francis Scott Key bridge in Baltimore after being struck by a container ship is both a human tragedy and an economic disaster. Six construction workers doing repair work on the bridge lost their lives when it plunged into the cold Patapsco River. The wreckage of the bridge now sits in the channel that connects Baltimore Harbor to the Chesapeake Bay, effectively closing the Port of Baltimore. Joe Kane, a fellow in Brookings Metro, talks about the economic impacts of the disaster and prospects for rebuilding the bridge.
