The strange sound coming from the Golden Gate Bridge was due to the balustrade on the renovated sidewalk. Due to the renovation of the balustrade, the strong wind that blows from the west side to the east side of the Golden Gate Strait comes to sound when passing through the balustrade.

``The new sound coming from the bridge is a known and inevitable phenomenon from a renovation project to combat the high winds on the bridge,'' said a statement released by Paolo Koslich Schwarz, a spokeswoman for the Golden Gate Bridge. The renovation project aims to make the bridge less susceptible to the effects of strong winds, and is necessary to ensure the safety of the bridge in the future.' It has been revealed that the repair was done.
