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.
Golden Hill Bridge in 1885. The town contracted for the trusses with the Berlin Iron Bridge Company, then a major producer of bridge trusses, and the bridge was completed for $1,000. In 1965, the state added a metal grid deck, and in 1970 it replaced the original deck supports with I-beams. In 1992, after the bridge was closed to vehicular traffic, the state began proceedings to consider replacement of the aging structure. It was further closed to pedestrians in 1996. The bridge finally underwent major restorative work in 2005, and is again open to traffic. Golden Hill Bridge The Golden Hill Bridge is
