The world famous Golden Gate Bridge in San Francisco is to get a $US50 million ($A73 million) suicide net after bridge bosses ruled that it was more important to save lives than preserve the structure's classic lines.
An average of 20 people commit suicide each year by climbing over the 1.2 metre railing and plunging about 75 metres to the San Francisco Bay below.
Last year 37 people leapt to their death from the 1,280-metre-long bridge that links San Francisco to Marin County to the north.
A further 17 have committed suicide so far this year.
The steel nets will hang six metres on each side of the bridge, extending six meters out, and will have a minimal impact on the landmark's profile, board members said.
"The net offers a way to do the most humane and highest-minded thing ... in a way that is aesthetically (minimal) as far as impacts on the bridge," said board member Charles McGlashan.
Officials estimate the barrier will cost up to $US50 million ($A73.16 million) to build, but there is still no decision on how to fund the project.
Officials will also have to undertake an environmental review to examine the effect of the suicide net on birds.
