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.
Suicides at the Golden Gate Bridge in the final blueprint. New barriers have eliminated suicides at other landmarks around the world, but were opposed for the Golden Gate Bridge for reasons of cost, aesthetics, and safety, as the load from a poorly designed barrier could significantly affect the bridge's structural integrity during a strong windstorm. Despite these concerns, on June 27, 2014, California approved a funding plan to install a suicide barrier. A volunteer group called the Bridgewatch Angels was founded by Pleasanton Police Lieutenant, Mia Munayer, in 2011. During every major holiday and while off duty, Munayer mobilizes hundreds of volunteers to patrol the bridge
