Suicide bridge

Suicide bridge is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Suicide bridge rather than just read about it. In short: A suicide bridge is a bridge that is frequently utilized by people for the purposes of suicide, most typically by jumping off and into the water or ground below. A fall from the height of a tall bridge into water may be fatal, although some people have survived jumps from high bridges such as the Golden Gate Bridge.

Key takeaways

  • Suicide bridge belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Suicide bridge to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Suicide bridge from memory before moving on to harder problems.

Reference excerpt

A suicide bridge is a bridge that is frequently utilized by people for the purposes of suicide, most typically by jumping off and into the water or ground below. A fall from the height of a tall bridge into water may be fatal, although some people have survived jumps from high bridges such as the Golden Gate Bridge. However, significant injury or death is far from certain; numerous studies report minimally injured persons who died from drowning. To reach such locations, those with the intention of ending their lives must often walk long distances to reach the point where they finally decide to jump. For example, some individuals have traveled over the 4.46-mile-long (7.18 km) San Francisco–Oakland Bay Bridge by car in order to jump from the Golden Gate Bridge.

Prevention

Suicide prevention advocates believe that suicide by bridge is more likely to be impulsive than other means, and that barriers can have a significant effect on reducing the incidence of suicides by bridge. One study showed that installing barriers on the Duke Ellington Bridge in Washington, D.C.—which has a high incidence of suicide—did not cause an increase of suicides at the nearby Taft Bridge. A similar result was seen when barriers were erected on the popular suicide bridge the Clifton Suspension Bridge, in the United Kingdom. Families affected and groups that help the mentally ill have lobbied governments to erect similar barriers. One such barrier is the Luminous Veil on the Prince Edward Viaduct in Toronto, Canada, once considered North America's second deadliest bridge, with over 400 jumps on record. Special telephones with connections to crisis hotlines are sometimes installed on bridges.

Bridges

Australia

The Sydney Harbour Bridge, the Mooney Mooney Bridge on the Central Coast (New South Wales), and the Westgate Bridge in Melbourne, Australia and the Story Bridge in Brisbane are considered suicide bridges. Sydney Harbour Bridge has a suicide prevention barrier. In February 2009, following the murder of a four-year-old girl who was thrown off the bridge by her father, the first stage of a temporary suicide barrier was erected on Westgate Bridge, constructed of concrete crash barriers topped with a welded mesh fence. The permanent barrier has now been completed throughout the span of the bridge. The barriers are costed at AU$20 million and have been reported to have reduced suicide rates on the Westgate by 85%. Suicide prevention barriers were installed on the Story Bridge in 2013; a three-metre-high barrier runs the full length of both sides of the bridge.

Canada

There are a number of suicide bridges in the Metro Vancouver area, the most frequented being the Lions Gate Bridge, which saw 324 suicidal incidents, including 78 jumps from 2006 to 2017. The High Level Bridge in Edmonton, Alberta, is considered a suicide bridge. It is unknown how many deaths have occurred at the bridge, but there have been at least 25 in total, with 10 being from 2012 to 2013. Many people have also survived suicide attempts at the bridge. A suicide prevention barrier has been installed along with signage and support phone lines. The Jacques Cartier Bridge in Montreal, Quebec, is considered a suicide bridge. In 2004, a suicide prevention barrier was installed. Until then the bridge saw an average of 10 suicides a year. The Prince Edward Viaduct, commonly referred to as the Bloor Viaduct, in Toronto, Ontario, was considered a suicide bridge. With nearly 500 suicides by 2003, the Viaduct was ranked as the second most fatal standing structure in North America, after the Golden Gate Bridge in San Francisco. Suicides dropped to zero after a barrier was completed in 2003. The Lethbridge Viaduct in Lethbridge, Alberta, also known as the High Level Bridge, is considered a suicide bridge. It is unknown how many deaths have occurred at the bridge since its opening in 1909. Suicide prevention signage has been installed at the entrance to the bridge, however no further prevention program is in development. The Angus L. Macdonald Bridge in Halifax, Nova Scotia, has been used for suicide attempts. As of 2010, safety barriers have been installed the full length of the pedestrian walkway. The Reversing Falls Bridge in Saint John, New Brunswick has had often use for those making suicide attempts. Efforts have been made by the city to install barriers, but they have struggled to secure provincial funds to do so. The Burgoyne Bridge in St. Catharines, Ontario, has had several suicides. In 2020, stainless steel netting was installed as a suicide prevention measure.

Czech Republic About 300 people have jumped to their death from the Nusle Bridge, in Prague, Czech Republic. Barriers almost 3 metres high were erected here in 1997 with the aim to prevent further jumps. In 2007, the fencing was topped off with a 3-foot-wide strip (0.91 m) of polished metal to make it impossible to climb. The Sítenský most in Kladno has also been described as a suicide bridge and "second Nusle". Between 2013 and 2018, 23 suicides were attempted there. Because it is only 15 metres (49 ft) from the ground, attempts are not always successful, however the bridge is easy to access and there is no suicide barrier.

New Zealand The Auckland Harbour Bridge and Grafton Bridge in Auckland have been known for suicides and suicide attempts, with multiple attempts to install suicide prevention barriers in recent decades.

South Africa 88 people have jumped to their death from the Van Stadens Bridge, near Port Elizabeth, Eastern Cape, South Africa. A barrier has since been installed.

South Korea

A frequently used suicide bridge in Seoul is the Mapo Bridge, locally known as "Suicide Bridge" and "The Bridge of Death". South Korean authorities have tried to counter this by calling the bridge "The Bridge of Life" and posting reassuring messages on the ledges.

Worked examples

Example 1 — a first encounter with Suicide bridge

Start with the simplest possible case. Write down what Suicide bridge claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Suicide bridge before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Suicide bridge ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Suicide bridge

In research
Suicide bridge appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Suicide bridge in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Suicide bridge is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bridges, Suicide by jumping, so understanding it makes those chapters shorter.
In everyday life
Look for Suicide bridge outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
