THE GOLDEN GATE Bridge is one of the most iconic megastructures in San Francisco , officially opening in 1937 to provide increased links from the city to Marin County , which was previously only accessible by ferry . Built at a cost of over $ 35 million , the suspension bridge was built by McClintic-Marshall Construction Company , which became part of Bethlehem Steel Corporation , alongside engineers Joseph Strauss and Charles Ellis and architects Irving Morrow and Leon Moisseiff .

The bridge incorporates walkways , in addition to six lanes , accessible for pedestrians , vehicle users and cyclists . The iconic colour was selected by Irving Morrow , who is responsible for the iconic walkways and overall design , but worked in collaboration with Ellis who was behind the structural , engineering elements to the megastructure . With over one million total rivets within the bridge structure , and twin towers which reach heights of nearly 750ft , the bridge successfully links both areas and has provided numerous advantages within the region , boosting the local economy and access within the regions .
