TED-Ed: Building the impossible: Golden Gate Bridge | Alex Gendler

Stretching 227 meters tall, two towers were assembled to support California's Golden Gate Bridge. They were just one of the challenges facing engineers Charles Ellis and Joseph Strauss.

Alex Gendler details the feat. [Directed by Anton Bogaty, narrated by Addison Anderson, music by Salil Bhayani, cAMP Studio].
