Engineering screwup turns Golden Gate Bridge into creepy wind siren

After work on the Golden Gate Bridge's sidewalks to bolster their wind resistance, nearby residents of San Francisco are complaining that the 1.7 mile-long structure makes a creepy droning noise when it's windy. The mysterious and unsettling tone is heard in videos posted by Alberto Martinez, Mark Krueger and @reedm. It's a spectacular example of engineering neglect.

Anthony J.:
"Engineers designed new sides for the sidewalk to help with wind resistance but didn't take into account the EXTREME sound it creates when wind passes through it. The bridge sings crazy songs now it's so trippy. It hurts the ears and unbearable it's that loud."
