What makes it epic compared to other bridges? Well except being in many films so more people knows about it.
It's universally considered to be a beautiful bridge. Compare and contrast with the old eastern span of the bay bridge. https://en.wikipedia.org/wiki/San_Francisco%E2%80%93Oakland_... You have to admit the old eastern span was just ugly.
It's both the bridge and the location/environment, e.g. the fog banks.

It's gotten quieter since 2017 - https://www.sfgate.com/bayarea/article/BART-noise-levels-dec...
"BART says", but as of 6 months ago I was compelled to buy ear plugs for my commute. There's a stretch just before West Oakland (Westbound) that I'm near certain has given me ear damage.
It used to be even worse.

#194According to following, engineers knew this sound would happen during high winds from the west. https://www.theguardian.com/us-news/2020/jun/06/golden-gate-...
> “We knew going into the handrail replacement that the bridge would sing during exceptionally high winds from the west, as we saw yesterday. We are pleased to see the new railing is allowing wind to flow more smoothly across the bridge.”

Here's a video from the company that built the new handrail:
https://www.youtube.com/watch?v=N-XCbsyRENI
From your article: "The wind retrofit project is designed to make the Bridge more aerodynamic under high wind conditions and is necessary to ensure the safety and structural integrity of the Bridge for generations to come,” Cosulich-Schwartz said."
This statement doesn't agree with the video's rationale for updating the railings. I'm guessing the new suicide net increased the wind loading, so the handrail had to be modified to reduce its wind loading. Without the suicide net project, I doubt the handrails would be changed. But the suicide net project is contentious politically, so they cannot admit this.
The new handrail uses long, unsupported plates. The old handrail was far more rigid:

#196I'm just glad they identified the source of the hum, many people are impacted for years by unexplainable sounds, and it is maddening. It took me and my neighbours a month to find the source of a hum that was resonating with our windows. It was torture, with midnight walks and lurking around potential sources, mapping nearby industrial sites, and questioning our sanity, while our windows were vibrating without a stop.…
My backyard backs in to a strip mall with an auto mechanic shop. We hear a high pitch sound some times of the day and when we step outside to inspect, we only hear a different sound from the shop behind - a typical machine running, but not necessarily unpleasant. Turns out the walls are able to mask the lower pitch sound somehow and let in only the unpleasant higher pitch sound to the inside of the house. I am not sure how to explain it to the shop owner, but we are just going to ignore it for now. I guess I need to look into insulation options :)

#197Does anyone know if they are planning on removing the slats? Maybe if they randomly changed the spacing of the slats if it would alleviate the problem ?
Why would they? It’s the perfect way to reduce property values in the area!

#198I hope somebody has a chance to make high-quality samples/recordings before it's fixed. I doubt we'll get the chance to hear an instrument like this again, accidental or not.
> before it's fixed Given that it was intentional, what makes you think it'll be "fixed"?
The article clarifies that "intentional" really just means "known about beforehand", and I imagine if enough people are annoyed they could "fix" it.

Two unrelated anecdotes: 1. A few years ago I spent some time in Falmouth, MA and there was an ongoing battle over newly installed wind turbines. The humming sound was getting to people, including to the point where they were getting headaches. Some people heard it and others didn't. The locals were going to war with the initiative. This article reminded me of that and I checked in on the ordeal. Looks like they shut…
We called them "partridge" they will stand on a hollow log and use it as a resonator. Sounds like a hit-n-miss engine starting up then petering our
