Tracking Daily Movements of the Bridge
In a normal day, the Bridge deck rises up a few feet at night when it gets colder and the steel in the cables shrinks and there is less traffic weight on it. It goes down in the daytime with rise in temperature and traffic load. It sways to the east when the wind comes off the ocean from the west. This exhibit displays actual measured movements of the bridge, which can be “played” forward and backward.
STATUS: This exhibit is currently at the Exploratorium.
