The height of the two towers is 225 m above the water level. The diameter of the cables of the main suspension is 92.4 cm and each of them is made up of 27 572 cables which, added together, lead to a total length of 128748 km (equal to one third of the average Earth-Moon distance).When it was completed in 1937, the Golden Gate Bridge was the longest suspension bridge in the world and over time it has become an internationally recognized symbol of the city of San Francisco.
