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.
Hell Gate Bridge Hell Gate Bridge The Hell Gate Bridge, originally the New York Connecting Railroad Bridge or the East River Arch Bridge, is a steel through arch railroad bridge in New York City. The bridge crosses the Hell Gate, a strait of the East River, between Astoria in Queens and Randalls and Wards Islands in Manhattan. The bridge is the largest of three bridges that form the Hell Gate complex. An inverted bowstring truss bridge with four spans crosses the Little Hell Gate (now filled in); and a fixed truss bridge crosses the Bronx Kill (now narrowed by fill). Together with approaches,
