Here's what to know:

— Collapse's cause: The cargo ship, which is called Dali, reported losing power just before it struck a column on the bridge. Watch the moment the bridge collapsed.

— Search suspended Tuesday: All six workers missing after the Francis Scott Key Bridge in Baltimore collapsed are presumed dead, and the search for them has been suspended until Wednesday morning.

— Bridge location: The bridge, part of I-695, once spanned the Patapsco River, a vital artery that along with the Port of Baltimore is a hub for shipping on the East Coast. A supply chain manager says to expect goods shortages in the coming days.
