Baltimore Bridge Collapse

Baltimore's port could be closed for months, keeping people out of work and leaving freighters looking for places to route their loads.

Containers carrying hundreds of tons of hazardous materials were on the ship, complicating the monumental cleanup.

Cargo ships have grown since the Francis Scott Key Bridge was built. Collisions have greater impact, physically and economically.

Mexican and Central American workers have been the lifeblood of the Baltimore economy, but they're also part of the "lowerarchy."

And there's no telling how long it'll take to reopen the port. Other East Coast ports will have to handle some of the shipping traffic.
