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.
West Gate Bridge dual-carriageway freeway bridge. The freeway corridor (including the bridge itself) carries a very high volume and occupancy of traffic, between 180,000 - 200,000 cars / trucks / motorcycles use it per day, according to VicRoads. This makes the West Gate Bridge and West Gate Freeway one of the busiest road corridors in Australia. However, being the only main direct link between Melbourne's CBD and the West, it is frequently congested during the morning and afternoon peaks (despite having 5 lanes in each direction) and is constantly busy 24/7, due to the number and type of vehicles coming in and out
