The quake-prone Bay Area is already a pretty precarious area for bridges, but now suspicious drone activity is also a concern for San Francisco’s famous Golden Gate.
Officials are now reportedly spotting drones near the bridge several times a month, and one even crashed into the road. Those San Francisco officials understandably have some security concerns, since the world-famous symbol of American engineering attracts 10 million visitors a year and ferries over 100,000 vehicles’ worth of commuters a day.
Of course, drone flybys are nothing new: the small, hovering, camera-equipped unmanned aircraft have been making sketchy appearances all around the world’s major landmarks this year. Just last week, a guy landed a drone carrying radioactive sand onto Japanese Prime Minister Shinzo Abe’s office roof. Earlier this year, another drone (sans contaminated granules) crashed near the White House, and others were seen around the Eiffel Tower.
With bridges in particular, drones can gain easy aerial access to the otherwise inaccessible structures. This can be good and bad: Some civil engineers think that we can use drones to survey the structrual condition of the beams and joints of a bridge—which can be especially advantageous with older structures. (The Golden Gate Bridge was built around 80 years ago.)
But law enforcement is on the lookout for people who might use the information-gathering technology for nefarious purposes. Last year, two men were arrested after they were caught flying drones near New York City’s George Washington Bridge, nearly coming within striking distance of an NYPD helicopter at 2,000 feet. Right now, laws surrounding personal and recreational drone use are still pretty nebulous.
As far as the Golden Gate Bridge goes, though, they take security pretty seriously. Since 9/11, the Golden Gate Bridge Highway and Transportation District received around $15 million in grants to beef up security. Sounds like some of that could be going toward anti-drone enforcement.
