Engineers blame $3m structural 'flaw' for Baltimore's Francis Scott Key bridge collapsing - and tens of thousands of bridges across US could also have fault

Engineers have blamed the deadly collapse of Baltimore's Francis Scott Key bridge on a design flaw that is present in tens of thousands of US bridges.
Several experts told DailyMail.com that the Maryland bridge was missing critical protection systems that would have stopped the the nearly 105,000 ton container ship from smashing into the bridge's support.
The Francis Scott Key Bridge was built in 1977 and anti-collision devices like fenders or protection cells were not introduced until the 1980s.
Experts said installing fenders would cost at least $3 million, but the collapse means a $15 million per day loss in economic activity and $1.5 million daily in state and local taxes - and that doesn't include the six men who are presumed dead.
Video of the 1.6-mile-long Francis Scott Key bridge collapsing into the Patapsco River after a cargo ship struck one of its piers at low speed created a surreal scene as the entire bridge appeared to crumble in one fell swoop.
