PaulOutWest Posted January 9, 2015 Share Posted January 9, 2015 I shot this image on the Golden Gate Bridge. I'm trying to figure out if it is part of the San Francisco Outdoor Warning System or just a general traffic siren of some kind. Pretty sure it is not one of the fog horns. I cave contacted the city but have gotten no response. Any ideas? Thanks Link to comment Share on other sites More sharing options...
spacecadet Posted January 9, 2015 Share Posted January 9, 2015 Not my neck of the woods, but Google images of the OPWS show round off-white speakers. Yours match the bridge in colour (International orange, if you didn't know, should be in the keywords!) so I'd say they belong to it. The website has a map of the speakers which unhelpfully has a picture of the bridge on its homepage. Link to comment Share on other sites More sharing options...
PaulOutWest Posted January 9, 2015 Author Share Posted January 9, 2015 Thanks Mark. The city map does show a speaker in the general area but it's not too specific. The other speakers in the city are rounded white speakers. My guess is that anything attached to the bridge has to fit in with its color and historical nature. I just messaged the city's dept of emergency management FB page. Link to comment Share on other sites More sharing options...
Johnnie5 Posted January 9, 2015 Share Posted January 9, 2015 This article mentions the loudspeakers in paragraph 6. Sounds like they are for security and maybe to discourage jumpers. http://www.sfcityguides.org/public_guidelines.html?article=1391&submitted=TRUE&srch_text=&submitted2=&topic=Bridges Link to comment Share on other sites More sharing options...
PaulOutWest Posted January 10, 2015 Author Share Posted January 10, 2015 Thanks Johnnie. I suspect that you are correct and the speaker is just part of the bridge's security system. I don't want to tag it as part of the Outdoor Warning System if I'm not sure. Link to comment Share on other sites More sharing options...
