"People who have never been to San Francisco or know very little about the city, at least know about the Golden Gate Bridge. The taut swag of its cables, recognizable in silhouette form, are an emblem of the city. Its color, International Orange, is associated specifically with the bridge. The bridge stands apart from the city—buffered by the parklands of the Presidio on the south end and the Marin Headlands on the north end—and its structure and natural setting complement one another. Very subtly, however, the bridge gets the upper hand over its environs. The bridge is obviously not as old as the hills that receive either of its ends, but the hills nevertheless appear to be there for the bridge. And the fog, which has always poured into San Francisco Bay through the Golden Gate strait, seems to serve the purpose of dramatically enhancing the bridge, concealing and unveiling its two towers and continually adjusting the natural light reflected on the bridge during the day. Ultimately, of course, the bridge serves us, making it possible for human traffic to travel to and from Marin County and beyond. Most thoughtfully, the bridge has a walkway on its eastern side so it is possible to cross the Golden Gate on foot to admire the views and ponder all that this bridge stands for. It was designed as a monument to progress, and if we are awed by the bridge, we must be awed by ourselves."
