The Golden Gate Bridge is a suspension bridge across the Golden Gate, the opening of the San Francisco Bay into the Pacific Ocean. As part of both U.S. Route 101 and California State Route 1, the structure links the city of San Francisco, on the northern tip of the San Francisco Peninsula, to Marin County. It is one of the most globally recognized cryptograms of San Francisco, California, and of the United States. It has been declared one of the contemporary Wonders of the World by the American Society of Civil Engineers. The Formers travel guide considers the Golden Gate Bridge “possibly the most beautiful, undoubtedly the most photographed, bridge in the world”. Today we are going to share a brief history of the Golden Gate so let’s have a look on “Voyage To Golden Gate San Francisco”.

For many years before the Golden Gate Bridge was built, the only way to get across San Francisco Bay was by ferry, and by the early twentieth century the Bay was clogged with them. In the 1920s, engineer and bridge-builder Joseph Strauss became convinced that a bridge should be constructed across the Golden Gate.

Many groups opposed him, each for their own selfish reasons: the military, loggers, the railroads. The engineering challenge was also enormous – the Golden Gate Bridge area often has winds of up to 60 miles per hour, and strong ocean currents sweep through a rugged canyon below the surface. If all that weren’t enough, it was the middle of the Great Depression, funds were scarce, and the San Francisco Bay Bridge was already under construction. In spite of everything, Strauss persisted, and Golden Gate Bridge history began when San Francisco voters overwhelmingly approved $35 million in bonds to construct the Golden Gate Bridge.

The now-familiar art deco design and International Red color were chosen, and construction began in 1933. The Golden Gate Bridge project was completed in 1937, a prominent date in San Francisco history. Strauss was a pioneer in building safety, making history with innovations including hard hats and daily sobriety tests. The Bay Bridge (which was being built at the same time) lost 24 lives while the Golden Gate Bridge lost only 12, an outstanding accomplishment in an era when one man was killed on most construction projects for every million spent.

Total length: Including approaches, 1.7 miles (8,981 feet or 2,737 m)

Middle span: 4,200 feet (1,966 m).

Width: 90 feet (27 m)

Clearance above the high water (average): 220 feet (67 m)

Total weight when built: 894,500 tons (811,500,000 kg)

Total weight today: 887,000 tons (804,700,000 kg). Weight reduced because of new decking material.

Towers:

746 feet (227 m) above the water

500 feet (152 m) above the roadway

Each leg is 33 x 54 feet (10 x 16 m)

Towers weigh 44,000 tons each (40,200,000 kg).

There are about 600,000 rivets in EACH tower.

One of the most interesting Golden Gate Bridge facts is that only eleven workers died during construction, a new safety record for the time. In the 1930s, bridge builders expected 1 fatality per $1 million in construction costs, and builders expected 35 people to die while building the Golden Gate Bridge. One of the bridge’s safety innovations was a net suspended under the floor. This net saved the lives of 19 men during construction, and they are often called the members of the “Half Way to Hell Club.”

Golden Gate Bridge Traffic Fact

Average crossings: About 41 million per year, counting both north- and southbound crossings, compared to 33 million crossing the first year it was open

Fewest crossings: January, 1982, during a storm which closed U. S. 101 north of the bridge. On January 6, only 3,921 southbound vehicles passed the toll gates

Most crossings: October 27, 1989, a few days after the Loma Prieta earthquake, when the Bay Bridge was closed. 162,414 vehicles (counting those going both directions) crossed the bridge that day

Total crossings: Through October 30, 2002, the Golden Gate Bridge Highway District reported 1,754,094,967 vehicles had crossed the bridge

Closures: The Bridge has been closed three times for weather, for gusting winds over 70 mph. It closed briefly for visits by President Franklin D. Roosevelt and French President Charles DeGaulle. It was also closed on its fiftieth birthday.
