Local studio MacDonald Architects has designed the safety nets recently installed on each side of the Golden Gate Bridge in San Francisco to prevent people from jumping from its sides.
Designed by MacDonald Architects on behalf of Golden Gate Bridge, Highway and Transportation District (GGBHT) – the state district that manages the bridge, the deterrent nets were completed on earlier this month.
According to the GGBHT, the nets were installed on 95 per cent of the 87-year-old bridge, with some sections currently under construction having vertical fences installed.
The marine-grade stainless steel nets were installed 20 feet (six metres) below the sidewalk and stretch 20 feet out from the bridge, suspended at intervals by red-painted steel arms that match the colour of the bridge.
"The net is a proven design"
They run through the whole 1.7-mile length (2.7 kilometre) of the bridge and were installed to prevent people from taking their own lives by jumping from the bridge.
They are meant to catch people who jump from the bridge, allowing the on-site security to retrieve the individuals from the net.
According to GGBHT, there have been an average of 30 confirmed suicides every year on the bridge for the past 20 years.
"The purpose of the net is to reduce the number of deaths associated with individuals jumping off the Bridge," said GGBHT in a statement.
"The net is a proven design that deters people from jumping, serves as a symbol of care and hope to despondent individuals, and, if necessary, offers people a second chance."
Work began on the project in 2017, and the GGBHT reported the net to be "already working as intended", saying that less than half of the average number of people died on the bridge in 2023.
"There have also been several instances where people have jumped into the net, and we, along with partner agencies, have successfully rescued many of them," added GGBHT.
The nets come after years of advocacy from local groups including the Bridge Rail Foundation, which comprises people in the community with personal connections to the issue.
"The prices are astronomical"
MacDonald Architects has been the main design consultant on the bridge since the 1980s, implementing transit retrofits like bike rails and improving the structure's seismic rating over the years.
The studio's principal Donald MacDonald spent years researching various suicide prevention barriers in order to submit recommendations to the local government on possible design solutions.
According to a report by the Guardian, the net was approved more than a decade ago but has faced numerous challenges including local complaints due to the historic nature of the bridge and construction delays, some stemming from a lawsuit launched by contractors.
MacDonald told Dezeen that the biggest challenges in the design were the variety of inputs from local interests, the impact of wind on the bridge when new aspects were installed along with the high costs of the project.
For the Golden Gate Bridge, the design called for modifications to the travellers – platforms installed under the bridge for maintenance.
"The prices are astronomical," said MacDonald. According to GGBHT, $224 million (£130 million) was spent on the installation.
The changes to the bridge also underwent a historical evaluation, according to MacDonald, who has installed a variety of deterrent systems from fences to nets on bridges in the United States and Canada.
"It had to comply with the national guidelines," he told Dezeen. "When I did it, there wasn't a lot of data available on bridges. So I had to work out a whole system evaluating the bridge in a historical format."
Other newer structures have become locations for suicide, sparking controversy from local communities.
These include the Heatherwick Studio-designed Vessell in New York City, a sculptural vertical walkway that was forced to close in 2021 after multiple suicides followed its 2019 opening, even after a "buddy system" was put in place by its owners.
