The Golden Gate Bridge acted as a musical instrument on Friday as the wind passed through its sacred arches, causing a sinister and ghostly melody heard for miles.

“Can someone explain to me why this strange sound has been going on for an hour at #SanFrancisco”, Alberto Martinez A tweeted from the Presidio.

The reason for the freezing air? Vibrating wind against new sidewalk guardrail slats installed along the cycle path of the span. “The new musical tones coming from the bridge are a known and inevitable phenomenon that stems from our modernization of the wind in very high winds,” said Paolo Cosulich-Schwartz of the Golden Gate Bridge, Highway & Transportation District, in a written statement. “As part of the design process, the district conducted extensive studies on the impacts of the project, including wind tunnel testing of a scale model of the Golden Gate Bridge under high winds.

These trials, as seen in a video here, showed that the bridge would “start to hum” when air passed freely over its roadway.

The strong winds on Friday, passing to the west through the 83-year wingspan, caused the melody. After the bridge sang its first bars, people, like this commuter drive on the roadway of the connection or that person five miles away in Lands End, posted videos of the moans of the international piece of metal orange.

Reactions to the bridge’s performance have been mixed. “The city is now a great David Lynch movie,” said KQED reporter Gabe Meline, while Toni Burton was of the opinion, “I think it’s such a pretty ‘noise.’ I say, don’t change it! But a person, whose sentiment was shared by many, said on twitter, “This is seriously going to make people lose their minds. Maybe me.

So far, there are no plans to modify the bridge to be silent; Cosulich-Schwartz said the new design is necessary to ensure the safety of the famous span.

After the Golden Gate Bridge trend on Twitter on Friday, it made headlines a day later for another reason: dozens of people protesting police brutality and the murder of George Floyd by Minneapolis cops, crossed the bridge, with some people spread on the sidewalks and in the streets. Organized by two teenagers, Tiana Day from San Ramon and Mimi Zoila from Marin County, this was the first Black Lives Matter event to be held on the bridge.
