The Port of Baltimore handles high volumes of auto imports, so while it's at a standstill, some cars and trucks will have to be diverted to other ports, which could raise costs.

Baltimore's port isn't one of the nation's largest, and some goods can be rerouted. But some auto companies are having to scramble, and the bridge disaster could spell trouble for local jobs.

A momentary loss of propulsion or electricity aboard the massive cargo vessel as it maneuvered in a tight channel in Baltimore may have triggered a cascade of events leading to the bridge collision.

Recovery efforts are underway for six people presumed dead in the Baltimore bridge collapse. NBC has dropped a former RNC chair as a contributor after backlash from the public and its network stars.
