If we were to start the comparison of the two bridges it would be rather unique comparison. First, let’s start the comparison with the build material of the two. The Brooklyn Bridge is made of Limestone, Granite, and Rosendale concret. The material used to make to The Golden Gate Bridge is steel along with some other concret at the very base of it. Any who the main material is steel.
Now looking at the design The Golden Gate Bridge is a suspension bridge while the Brooklyn Bridge is a hybrid of a suspension and cable-stay. This is somewhat important to answer one of the later parts of this assignment. Along with the comparison both bridges were built in May, just a cool little point out. Most of all in the comparison, they are photographed in many ways all with very similar features of the bridge as the focus points.
Now to look at what is commonly seen in the photos of each bridge. When scouring the internet for photos I noticed a trend. That trend being the Brooklyn Bridge commonly is shot showing its towers and cable structure whereas the Golden Gate Bridge is shot as a whole. The reason I think this may be is the Brooklyn Bridge at the time was unique and had a very beautiful neo-gothic design resulting in the cables being laid out in an exponential fashion. In the case of the Golden Gate Bridge it has the suspension cables running perfectly vertical from the bridge.
Taking a look at the bridges architectural design I think there is a lot it reveals. For example the Neo-Gothic design of the Brooklyn Bridge was indicative of the more ornate and decorative style of the Romantic movement that America was transitioning out of during the time. The Brooklyn Bridge has more English influences. The Brooklyn Bridge came out of the industrial revolution were advancements in technology and engineering made it possible. On the other hand The Gold Gate Bridge is Art Deco style and has French influences. The Golden Gate Bridge was built after the 1906 earthquake and Fire in San Francisco. Suspension was considered the most logical at the time
Now to answer the last and final point, why the bridges have only been renovated rather than removed. Both bridges are icons for the cities in which they are located. The Brooklyn Bridge is on historic preservation lists which protects the design from being changed other than to restore or retrofit. I think The Golden Gate Bridge also follows suit.
