Happy Birthday Golden Gate Bridge – 75th anniversary festivities, history, and solar beacon


via Wikipedia


…it was a larger than life engineering project undertaken against dangerous odds and it opened 75 years ago on Sunday against vehement protest, at the cost of 11 lives.

One of the most astonishing and admired man-made wonders of the world, gracing millions of postcards, featured in countless films, the bridge was not at first welcomed with open arms.

Ferry operators and environmentalists opposed it, and many engineers doubted such a daring leap over a treacherous Pacific Ocean strait could be built. The military worried a collapsed Golden Gate span could block access to the Bay in war time.

The 75th anniversary celebration will have a fireworks show, bands, artist exhibitions, history tours, and more.




Solar Beacon

Solar Beacon is an art installation on top of the Golden Gate Towers that reflects the Sun’s light throughout the Bay Area, calling attention to the man-made structure’s 75th anniversary using the brightest natural light available. Observers of Solar Beacon will see two points of light, one on each tower top, that are bright as the Sun, but much smaller in size.

Through an online interface, the public can schedule a time-based performance, during which the observed spots of light will appear to turn on and off. Because the reflected light is projected in a narrow beam a half degree across, the performance only appears to a region around the observer (e.g. 12m at 2 km), but it can be seen by anyone in the Bay Area who has a direct view of the tops of the Golden Gate Bridge tower.
