The Golden Gate Bridge wanted people to celebrate its 75th birthday even if they couldn’t be there in person.

So 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 bridges through the Google Maps API. Each bridge could be added only once, so discovering available bridges became part of the experience.

Together we built the longest bridge the world has ever seen.
