In a bid to end suicides from the Verrazzano-Narrows Bridge, the MTA confirmed Friday that it will begin installing prototype suicide-prevention fencing as part of a feasibility study.

“There are unique and complex challenges involved in retrofitting a major suspension bridge that wasn’t originally designed with fencing,” Metropolitan Transportation Authority spokesman Aaron Donavan told The Post.

He added that wind restrictions, weight requirements, traffic, emergency response accessibility and worker safety are among the key concerns.

Daniel DeCrescenzo, acting president of MTA Bridges and Tunnels, recently informed councilmen Steven Matteo (R-Staten Island) and Justin Brannan (D-Brooklyn) of the agency’s plan in a letter saying it takes the suicide issue “serious” but faces “unique and complex challenges” in retrofitting the bridge with new equipment.

He also said the MTA would “install prototypes” along the Verrazzano as part of the barrier testing. No timetable or cost estimates were provided by the agency.

Matteo and Brannan represent the Staten Island and Brooklyn sides of the bridge, respectively, and have repeatedly called for suicide-prevention barriers on the bridge.

Instead, the MTA’s answer to the long list of leapers has been installing additional security cameras and signs reading, “Life is worth living,” above a series of suicide-hotline phones along the bridge’s two decks.

“This is definitely a step in the right direction, and I am hopeful that we may finally be on the path to preventing future tragedies,” Matteo said.

Brannan, however, said he’s “not sure why we need a study” when “we’re looking to save lives.” He said the MTA only needs to look to the West Coast for answers.

As the Post reported in June, Brannan wants the MTA to build a massive suicide-prevention barrier along the Verrazzano similar to a $211 million barrier going up along the Golden Gate Bridge overlooking San Francisco Bay.

The Golden Gate Bridge, Highway and Transportation District expects to complete its $211 million suicide barrier project by 2021, which has been plagued by cost overruns. It will feature a 380,000-square-foot-net running 20 feet below the top deck on each side of the Golden Gate, where more than 1,700 are estimated to have taken their lives by jumping since opening 82 years ago.
