Work officially began this week on a net under the Golden Gate Bridge intended to prevent and deter the dozens of suicides that take place at the iconic landmark each year, CBS San Francisco reported.More than 1,500 people are thought to have died there over the bridge’s 80-year lifespan.The stainless steel net, located about 20 feet below the bridge’s sidewalk, will span 1.7 miles of roadway on each side of the bridge and extend 20 feet out over the water.It will be built over a period of four years, at a cost of just over $200 million drawn from a mix of federal, state and local sources.In 2016 alone, 39 people died by suicide there. Bridge patrol officers also conducted 184 successful interventions in 2016 to keep people from harming themselves.
