On November 16, 2023, just before 8:00 a.m., hundreds of pro-Palestinian protesters formed a human chain across the San Francisco Bay Bridge, blocking all westbound traffic and trapping tens of thousands of vehicles in a five-mile backup. Among those vehicles were three trucks associated with the University of California, San Francisco, health system. Each was transporting organs that were set to be transplanted later that day, and the couriers, who had budgeted just 30 minutes of travel time, had their arrival delayed by nearly four hours.
