How the Golden Gate Bridge was constructed

During the construction of the iconic Golden Gate Bridge in the 1930s, a unique safety net system was employed to protect the workers from falls and accidents. This safety net, often referred to as the "Bridge Builders' Safety Net," played a crucial role in ensuring the well-being and security of the construction crew. The safety net was a remarkable engineering feat in itself. It consisted of a vast network of thick nylon ropes intricately woven together to create a strong and flexible mesh. The net spanned the entire length and width of the bridge, positioned directly beneath the workers as they carried out their tasks at dizzying heights. The primary purpose of the safety net was to catch any workers who might slip, stumble, or fall during construction. The net's construction and strategic positioning allowed it to absorb the impact of a fall, significantly reducing the risk of injury or fatality. Its installation served as a constant reminder to the workers of the potential dangers they faced daily. The net was suspended from a series of steel cables attached to the bridge's main supporting structures. It hung approximately 10 feet below the workers, providing enough clearance to cushion a fall but not so much as to create an excessive free fall distance. Its placement was carefully calculated to strike a balance between safety and practicality. While the safety net was primarily designed to prevent falls, it also facilitated the movement of materials and equipment across the bridge. Instead of having to lower heavy tools or components down to the ground level, workers could drop them onto the net, where they would be retrieved and repositioned as needed. This ingenious method not only improved efficiency but also reduced the risk of objects falling onto the ground or into the water below. The Bridge Builders' Safety Net proved to be instrumental in protecting the workers during the construction process. According to historical records, it saved the lives of 19 men who fell from the bridge during its four-year construction period. These fortunate individuals would have faced almost certain death if it hadn't been for the net's presence. The net was constantly maintained and inspected to ensure its integrity. Any damaged sections were promptly repaired or replaced to guarantee its continued effectiveness. The workers had a sense of security knowing that the safety net was there to catch them if they ever lost their footing. As the construction of the Golden Gate Bridge neared completion, the safety net was no longer needed. Its removal marked a significant milestone, indicating the successful conclusion of one of the most ambitious engineering projects of the era. However, the legacy of the Bridge Builders' Safety Net lives on, as it serves as a testament to the ingenuity, dedication, and commitment to safety of the workers who built this iconic structure.

In 1987 an estimated 800,000 people flocked to the the Golden Gate Bridge for its 50th anniversary. The weight of the large crowd caused the bridge to sag 7 feet, flattening its usual convex shape. Engineer Daniel E. Mohn reaffirmed the bridge was not overstressed as a result of Bridgewalk '87.

On September 25, 2000, 19-year-old Kevin Hines attempted to end his own life by jumping off the Golden Gate Bridge. Plunging over 220 feet at a speed of 75 miles per hour, he hit the water below, shattering three of his vertebrae and narrowly missing severing his spine by two millimeters. Despite the odds, he miraculously survived the impact. Upon realizing he was still alive, an intense will to live surged within him. Yet, the weight of his clothes continuously pulled him beneath the surface of San Francisco Bay. For what seemed like an eternity, he struggled to resurface briefly, gasping for air, just enough to hold on to life. Suddenly, he felt an unusual force from below lifting him above the water's surface, where he remained until the Coast Guard arrived. It was only later that he discovered the mysterious presence keeping him afloat: a sea lion had been supporting his body until the rescue boat arrived, as eyewitnesses had observed. His story gained major media coverage and he has since become a motivational speaker and advocate for suicide prevention.

There were three main processes for constructing the Golden Gate Bridge. The first was building the towers and concrete anchors, the second was raising the cables and the third was dropping the vertical cables, laying the steel road deck, and building the Golden Gate Bridge highway.

China builds the big infrastructure now

Lunchtime 🏗️

@lawyer4laws Took 4 years then. It would never be built today. Just look at the high speed rail 7 billion dollars later.

I'm pretty sure we'll neverbuild anything close to that again. We have no vision.
