SAN FRANCISCO, CA – The Golden Gate bridge is now singing and on some days, it can be heard for miles around the San Francisco area. The cause? New slats installed on the bridge’s bike path vibrate in the window, creating the eerie tones. Designers of the upgrades knew the bridge would hum after performing tests in a wind tunnel on scale models of the project.
“The Golden Gate Bridge has started to sing,” Paolo Cosulich-Schwartz, a spokesman for the Golden Gate Bridge, Highway and Transportation District said, “The new musical tones coming from the bridge are a known and inevitable phenomenon that stem from our wind retrofit during very high winds.”
On days with high winds spanning across the bridge, the humming begins. Here are some videos of what is going on.
