The Golden Gate Bridge is a 1.7 mile long suspension in San Francisco that had several design constraints considered in designing this bridge. With the large length of the Golden Gate Bridge, strong winds common to the area would cause more torque and twisting of it than a shorter bridge. Due to the windy conditions in the area, designers had to strengthen the support of the bridge by adding truss causeways, so the harsh winds would pass through it. San Francisco is also known to have frequent earthquakes which resulted in the designers adding even more support to the bridge. In order to prevent corrosion, they painted the bridge with a sealant to protect it against the water and humidity.
