The Golden Gate National Parks Conservancy asked us to find a way for people to celebrate the 75th birthday of the most famous bridge in the world, even if they couldn’t be there in person.

To make this a reality, we invited people to use the digital equivalent of bridges: social media. For the first time ever, people could connect across Twitter,Facebook, Google+, country borders and bodies of water simply by adding a bridge using the Google Maps API. Together we built the longest bridge the world has ever seen.
