When it opened to vehiÂcle trafÂfic in May, 1937 the GoldÂen Gate Bridge was the longest susÂpenÂsion bridge in the world. Since then eight bridges have surÂpassed it in length, but the iconÂic interÂnaÂtionÂal orange span is still the most phoÂtographed bridge in the world. This month marks the GoldÂen Gate’s 75th anniverÂsary and the CalÂiÂforÂnia HisÂtorÂiÂcal Society’s exhibÂit, A Wild Flight of the ImagÂiÂnaÂtion, celÂeÂbrates the event with a look at the bridge’s conÂstrucÂtion. The exhibÂit has also been made availÂable as a free eBook for the iPad, which includes hisÂtoric phoÂtographs by Ansel Adams and Dorothea Lange as well as a short film of bridge designÂer Joseph Strauss speakÂing to a reporter durÂing the bridge’s conÂstrucÂtion. At the time, experts said that the GoldÂen Gate strait’s feroÂcious winds and strong, swirling curÂrents would make conÂstrucÂtion imposÂsiÂble. But the design introÂduced deflecÂtion theÂoÂry, which utiÂlizes a thin, flexÂiÂble roadÂway and long cables that reduce strucÂturÂal stress.
The interÂacÂtive app is accomÂpaÂnied by a musiÂcal score—the openÂing selecÂtion from comÂposÂer Rob Kapilow’s ChrysopyÂlae, Greek for “GoldÂen Gate.” EarÂly users of the eBook reportÂed glitchÂes with the app’s audio. The culÂprit may have been the side mute switch, which must be flipped off for the audio to work. Also, make sure your iPad’s volÂume is up. Like the exhibÂit in the society’s San FranÂcisÂco museÂum, the app includes access to images of some 350 objects and ephemera relatÂed to the span’s conÂstrucÂtion. Almost as nice as a walk across the bridge’s 1.7 miles, and not nearÂly as windy.
