That incident ended safely, but others have not.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Since the bridge opened in 1969, more than 470 people have died by suicide, according to data from the San Diego County Medical Examiner\u2019s Office.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Caltrans recently <a href=\"https:\/\/www.sandiegouniontribune.com\/2026\/06\/10\/anti-suicide-barrier-for-coronado-bridge-clears-key-hurdle\/\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external noopener noreferrer nofollow\">secured a permit<\/a> to build a long-awaited barrier to prevent suicides on what is now the country\u2019s deadliest bridge. The transportation agency also plans to replace all cameras on the bridge and install 20 that will use artificial intelligence technology as part of the $145 million project.<\/p>\n<p class=\"wp-block-paragraph\">The 8-foot vertical steel wire mesh barrier will span the entire length of the bridge along both sides of the bridge\u2019s 34-inch concrete guardrails. The barrier will be supported by 8-foot-tall posts and secured by tension cables.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">At its June meeting, the California Coastal Commission approved the permanent barrier design after a staff <a href=\"https:\/\/documents.coastal.ca.gov\/reports\/2026\/6\/w17b\/w17b-6-2026-report.pdf\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external noopener noreferrer nofollow\">report<\/a> recommended the design was the \u201cleast visually intrusive.\u201d The approved barrier is 87 percent transparent and preserves views of the bay, according to the report.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">The commission\u2019s approval requires implementing a \u201cVisual Mitigation Plan\u201d that proposes improving views of the bay for pedestrians by reducing the height of a fence at the Bayshore Bikeway in Coronado and adding new murals in Barrio Logan.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Aside from the physical barrier, Caltrans spokesperson Aaron Hunter said, the AI cameras will detect unusual activity on the bridge and automatically notify the CHP and Caltrans.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Caltrans would not confirm whether the AI cameras on the bridge will work like the ones at the CHP <a href=\"https:\/\/www.cbsnews.com\/losangeles\/video\/chp-la-communications-center-using-ai-to-prevent-accidents-before-they-happen\/\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external noopener noreferrer nofollow\">LA Communications Center<\/a>. Those cameras detect pedestrians and stalled vehicles to help prevent accidents before they happen.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Steve Welborn is a public affairs manager for Caltrans. He said the state agency is still in the design phase and has not executed a contract for the AI tech yet.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">\u201cThe technology may be used to monitor the bridge,\u201d he said, but added that since details are still being worked out, it would not be accurate to say the cameras will be used to prevent suicides.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Up until last year, San Francisco\u2019s Golden Gate Bridge was the deadliest in the country, but since officials installed suicide prevention nets, suicides have dramatically decreased <a href=\"https:\/\/injuryprevention.bmj.com\/content\/32\/3\/498\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external noopener noreferrer nofollow\">by 72 percent<\/a>.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">The Coronado Bridge is now the deadliest suicide bridge in the United States, said John Austin, a general surgery resident and trauma researcher at UC San Diego, who analyzed bridge mortality on the Coronado Bridge before and after Caltrans added <a href=\"https:\/\/voiceofsandiego.org\/2020\/04\/21\/one-year-in-bird-spikes-havent-stopped-coronado-bridge-suicides\/\" data-wpel-link=\"internal\" rel=\"nofollow noopener\" target=\"_blank\">metal bird spikes<\/a> to keep people from jumping. The <a href=\"https:\/\/link.springer.com\/article\/10.1186\/s40621-026-00671-8\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external noopener noreferrer nofollow\">study<\/a> found that Caltrans officials knew about the need for a permanent barrier to prevent suicides, but installed call boxes and metal bird spikes instead.<\/p>\n<p class=\"wp-block-paragraph\">\u201cThis ineffective, underinformed public policy decision\u2014made without significant input from healthcare stakeholders or experts\u2014cost $420,000 and has failed to reduce the suicide rate since its installation,\u201d the study reads.<\/p>\n<p class=\"wp-block-paragraph\">Dr. Jennifer Lewis, a UC San Diego professor and mental health clinician who lives in Coronado, said it\u2019s painful that Caltrans didn\u2019t install the barrier sooner.<\/p>\n<p class=\"wp-block-paragraph\">She said some residents have witnessed a suicide and have felt helpless waiting for a solution.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">\u201cOur community has become traumatized,\u201d she said. \u201cWe have secondary trauma.\u201d\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Hunter, the Caltrans spokesperson, said it has taken the agency years to add a permanent effective barrier to the Coronado Bridge because of engineering difficulties, lengthy environmental reviews and planning, and plans to construct a walkway under the bridge that will be used for maintaining it.<\/p>\n<p class=\"wp-block-paragraph\">\u201cIt\u2019s a unique project for Caltrans because we normally don\u2019t do these types of projects, we\u2019re maintaining roads and repairing pavement,\u201d Hunter said. \u201cThe bridge is a unique design and there were a lot of things we had to look at in order to make this happen.\u201d<\/p>\n<p class=\"wp-block-paragraph\">Documents further detail the project is scheduled to begin in October and will work in two phases that will each take a year to complete. Phase one involves adding the vertical barrier, new cameras on existing light posts and signage on the northbound side of the bridge. Phase two will cover the southbound side.\u00a0<\/p>\n<p>\u2018Something Was Kind of Nothing\u2019\u00a0<\/p>\n<p class=\"wp-block-paragraph\">In 2018, the California legislature attempted to fast-track the funding, design and construction of the permanent physical barrier on the bridge by passing SB 656.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">The legislation fast-tracked the funding, design and construction of a permanent barrier. It also established an advisory committee to advise the agency on an effective suicide deterrent system.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Professor of Surgery at the UC San Diego School of Medicine, Dr. Amy Liepert joined the Caltrans Advisory Committee in 2019. She was there representing the trauma center\u2019s surgical team as a UC San Diego Health Surgeon that treats individuals who survive falls from the Coronado Bridge. Her motivation to fight for a permanent barrier, she said, came from witnessing the pain of a grieving mother of a teenager who died after surviving the fall.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">\u201cTen years is a very long time in the making, and it\u2019s been known since the bridge was installed that this needed to be done,\u201d Liepert said.<\/p>\n<p class=\"wp-block-paragraph\">Liepert co-authored the study with Austin and 11 more San Diego trauma surgeons, general surgeons and surgery residents that found that the measures taken to prevent suicides on the Coronado Bridge up until now have been completely ineffective and expensive.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">The \u201cSan Diego-Coronado Bridge Case\u201d<a href=\"https:\/\/link.springer.com\/article\/10.1186\/s40621-026-00671-8#data-availability\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external noopener noreferrer nofollow\"> study<\/a>, published in May, found that there was no decrease in suicides after Caltrans installed call boxes and a bird spike barrier. Caltrans could not provide a cost for the call boxes, but said the bird spike barriers cost $420,000.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">\u00a0\u201cIt\u2019s frustrating that with well-meaning intentions, there was a waste of public dollars for very ineffective solutions,\u201d she said.<\/p>\n<p class=\"wp-block-paragraph\">Austin, the UCSD Trauma resident and co-author of the study, said the study was necessary to quantify the public health issue trauma surgeons witness and process in the trauma bay at the Hillcrest Medical Center. Every person who jumped, on average, still had 28 years ahead of them, he said.<\/p>\n<p class=\"wp-block-paragraph\">\u201cI hear people say, \u2018Something is better than nothing,\u2019 but something was kind of nothing in this particular case,\u201d Austin said.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Over the years, trauma surgeons have seen younger, physically able persons, and more <a href=\"https:\/\/voiceofsandiego.org\/military-suicide-investigation\/\" data-wpel-link=\"internal\" rel=\"nofollow noopener\" target=\"_blank\">military servicemembers<\/a> among people who jump from the bridge, Liepert said.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Coronado resident and retired firefighter Wayne Strickland created the<a href=\"https:\/\/www.facebook.com\/groups\/2111694068936163\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external noopener noreferrer nofollow\"> Coronado-SD Bridge Suicide Prevention<\/a> Facebook group to share his advocacy efforts in 2019, a year after he told the Voice of San Diego he was disappointed to see <a href=\"https:\/\/voiceofsandiego.org\/2018\/08\/09\/coronado-bridge-suicide-barrier-pushed-until-2019\/\" data-wpel-link=\"internal\" rel=\"nofollow noopener\" target=\"_blank\">bird spikes<\/a> over a fence deterrent.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">\u201cIt breaks my heart that it wasn\u2019t done sooner so that these lives wouldn\u2019t have been lost. If they would have built the bridge with the fence or vertical net, it would have saved hundreds of lives. Over 500 lives have been lost and it would have been all preventable,\u201d Strickland said.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">His posts to the Facebook group in support of a permanent barrier get comments from opponents of the project who argue that a person in crisis will \u201cjust find another way.\u201d<\/p>\n<p class=\"wp-block-paragraph\">But studies have proven that the theory isn\u2019t true, said Johns Hopkins Professor and Director of the Anxiety Disorders Clinic Dr. Paul Nestadt who co-authored a 2022 study that showed that people don\u2019t just go somewhere else to commit suicide when they\u2019re deterred by a permanent barrier.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">In Washington, D.C., when an anti-suicide fence was installed on the Duke Ellington Memorial Bridge in 1986, suicides decreased 90 percent, despite being just feet from another lethal jump site. Suicides at the site nearby did not increase.<\/p>\n<p class=\"wp-block-paragraph\">Nesdat treats suicide survivors and researches access to suicide. He said every person in his care right now is grateful to be alive and does not want to die.<\/p>\n<p class=\"wp-block-paragraph\">It\u2019s like finally, prayers have been answered, said Raquel Nelson, a San Diego resident who lost her late husband to suicide on the bridge in Feburary 2014.<\/p>\n<p class=\"wp-block-paragraph\">Brandon Nelson was a positive person and always wanted to help everyone, but he struggled more than people knew. He was having a mental health crisis when he drove himself to the bridge.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Raquel arrived while he was still there, but crisis teams kept them apart. There was no barrier to stop him.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">\u201cIt couldn\u2019t save our loved one\u2019s life \u2026 but it gives me hope other lives can be saved,\u201d she said.\u00a0<\/p>\n<p>\n\tRelated Posts<\/p>\n","protected":false},"excerpt":{"rendered":"On June 14, Coronado police sent a warning to residents: Expect traffic on the San Diego-Coronado Bridge due&hellip;\n","protected":false},"author":2,"featured_media":415108,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[7,9,8],"class_list":["post-415107","post","type-post","status-publish","format-standard","has-post-thumbnail","category-california","tag-california","tag-california-headlines","tag-california-news"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/415107","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/comments?post=415107"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/415107\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/415108"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=415107"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=415107"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=415107"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
