Distress signal from ship before U.S. bridge collapse; detailed analysis of route.

Authorities say they were able to prevent many cars from being involved in the accident by restricting traffic on the bridge after receiving the distress call. In an accident that occurred in the early hours of the 26th in Baltimore, the largest city in Maryland, in the eastern United States, a large cargo ship collided with the piers of a bridge, causing the bridge to collapse and killing six of the eight workers. The governor said at a press conference that prior to the accident, the ship had sent out a distress signal.
