The Baltimore bridge disaster is what happens when 95,000 tons of modern cargo ship meets America's aging infrastructure, experts say

• Baltimore's largest bridge collapsed after a cargo vessel, the Dali, crashed into it.
• Experts told BI that a mechanical failure aboard the ship could have caused the crash.
• The bridge was never built with modern container ships in mind. 

The destruction of Baltimore's largest bridge early Tuesday morning has raised major questions about how such a disaster could have happened.
