Explore the construction of California’s Golden Gate Bridge, and dig into the engineering innovations that made the structure possible.

--

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. Even before construction began, many thought the project impossible: the strait was home to powerful winds, constant fog, and earthquakes. So how was this iconic bridge created? Alex Gendler details the feat.

Lesson by Alex Gendler, directed by Anton Bogaty.
