Golden Gate Bridge wanted it to be painted with black and yellow stripes to ensure visibility by passing ships. Senior engineer Charles Alton Ellis, collaborating remotely with Moisseiff, was the principal engineer of the project. Moisseiff produced the basic structural design, introducing his "deflection theory" by which a thin, flexible roadway would flex in the wind, greatly reducing stress by transmitting forces via suspension cables to the bridge towers. Although the Golden Gate Bridge design has proved sound, a later Moisseiff design, the original Tacoma Narrows Bridge, collapsed in a strong windstorm soon after it was completed, because of an unexpected aeroelastic flutter.
Sky Gate Bridge R Sky Gate Bridge R , serving the Kansai International Airport of Osaka, Japan, is the longest double-decked truss bridge in the world. It carries six lanes of automobile traffic on top and two of rail below, over nine truss spans. It links the mainland to the artificial island on which the airport is built. The Sky Gate Bridge is a continuous truss bridge that measures 3,750 meters long, 29.5 meters wide (6 lanes), and 25 meters at its highest point in the center. The bridge commenced construction in June 1987, and was completed in March 1994. The bridge was damaged
