A plan to add a suicide barrier and seismic upgrade to the Golden Gate Bridge requires more testing, as tests last month on a bridge model showed the center span being damaged by high winds coming in at an angle, The Marin Independent Journal reports.
The bridge model, with the suicide-prevention netting and added earthquake protection, performed well at horizontal winds of over 100 mph but became unstable when the wind flow was changed by 1 degree, the newspaper reported.
A ceremony was held in April for the start of construction of a suicide-deterrent barrier.
The stainless-steel net is scheduled to be installed in mid-2018, according to the Golden Gate Bridge Highway & Transportation District. It will be installed 20 feet below the sidewalk along both sides of the 1.7-mile bridge and extend 20 feet out over the water. It is expected to take four years to build and cost $211 million.
The bridge was the site of 39 suicides in 2016, and bridge patrol officers prevented 184 attempts, the website said.
