Blurring Bridge

When the fog in San Francisco has reduced 30% in the past 100 years, what else that is happening in the environment can we perceive? The project aims to link human perception with fog, water, infrastructure and climate change.

The intervention is a retractable façade system installed on Golden Gate Bridge in San Francisco which collects water from fog. The idea behind is to address the current drought and make the process visible by hiding the landmark bridge as a reminder of climate change. The façade consists of 120 hidden curtain rollers that would be activated to wrap the bridge during the fog. Each retractable curtain is made of hydrophilic water-condensing mesh and free-hanging steel chains. Water flowing along hanging chains in funicular shapes turns into rain curtains that fall on green belts and can purify water. The project is a speculative infrastructure system that reveals fog as the indicator of climate change, and questions how to create more intimate relationships between nature, city and its citizens.
