The Bay Bridge connecting San Francisco with Oakland (and most of the continent) has been closed for several days. SF Chronicle :
The bridge was shut down Tuesday evening. High winds and heavy
traffic loosened a pair of tie-rods and a steel bracket that was
installed Labor Day weekend to take pressure off a fracture discovered
in a structural beam – an eyebar – on the eastern span.
The 5,000-pound assembly crashed onto the upper deck, totaling three cars during the evening commute.

Ney compared the scenario to a metal paper clip that snaps when it’s repeatedly bent.
