After a retrofit to the roadway guardrails to make it more aerodynamic, the Golden Gate Bridge has started to sing (The Guardian). The whistling drone can be heard as far as three miles away and has been described as deafening in the immediate environs. I’ve been reading as much as I could find about this development because I’ve always been fascinated by — no pun intended — wind instruments, such as the Aeolian harp. I can’t find anything suggesting that the guardians of the Gate are planning further repairs to mute the bridge. The singing seems to be restricted to times of high winds through the Golden Gate from the west.
