Construction of the Golden Gate Bridge in San Francisco, an American engineering treasure and widely recognized symbol of the grandeur of the United States, began amid civic pride, pomp and circumstance on this day in history, Jan. 5, 1933. 

"The start of construction was met with great delight," the Golden Gate Bridge Highway and Transportation District website notes.

"A celebration at nearby Crissy Field went on for hours with at least 100,000 people in attendance. A festive parade through the Marina District began at 12:45 p.m. Navy planes flew in formation and engineering students carried an 80-foot replica of the bridge."

The suspension bridge spans the Golden Gate, the narrow strait of turbulent water that separates the Pacific Ocean from San Francisco Bay. It connects the City of San Francisco in the south with Marin County to the north. 

The Golden Gate Bridge boasted the world's longest bridge span (4,200 feet) and tallest bridge towers (746 feet) upon its completion. Its length was surpassed by the Verrazzano-Narrows Bridge in New York City in 1964 and by other bridges since.

The Golden Gate Bridge opened, remarkably, in May 1937, little more than four years after San Francisco Mayor Angelo Rossi and Golden Gate Bridge and Highway District board president William P. Filmer turned the first pile of dirt with ceremonial golden spades.

President Herbert Hoover sent a telegram of congratulations to celebrate the occasion. 

The Golden Gate Bridge symbolized the audacious daring of American spirit even amid global economic calamity.

Built during the Great Depression, the Golden Gate Bridge symbolized the audacious daring of American spirit even amid global economic calamity. 

Cincinnati native, part-time poet and bridge enthusiast Joseph Baermann Strauss was the chief engineer of the colossal project.

He was a diminutive powerhouse of a man, slightly built and standing just 5 feet 3 inches tall. Still, he tried out for the University of Cincinnati football team, where he was injured badly, while being voted class president and class poet by his college classmates.

"Strauss was a prolific engineer, constructing some 400 drawbridges across the U.S. He dreamed of building 'the biggest thing of its kind that a man could build," PBS American Experience writes.

"In 1919, San Francisco's city engineer, Michael O'Shaughnessy, approached Strauss about bridging the Golden Gate. Strauss caught fire with the idea, campaigning tirelessly over the next decade to build the bridge."

PBS adds, "In November 1930, a year into the Great Depression, voters at last supported a bond issue for Strauss' bridge. The ambitious project finally had its green light." 

His plans included an innovative life-saving measure: a safety net suspended under the floor of the bridge.

"The net proved an invaluable precaution as it saved the lives of 19 men," notes History.com. "These men became known as members of the ‘Half-Way-to-Hell Club.' Despite such safety measures, 11 men died during the bridge's construction."

The Golden Gate Bridge is just one of several of America's most incredible feats of art, architecture and engineering built during the Great Depression.

It's joined on that list by the Empire State Building, Hoover Dam and Mount Rushmore, among other structures that help define the American landscape today.

The Golden Gate Bridge combines, perhaps better than any other bridge in the world, stunning architectural beauty with critical transportation necessity.

The strait now known as the Golden Gate earned its name from explorer and U.S. Army officer John C. Fremont in 1846, who considered the passage "a golden gate to trade with the Orient."

Just two years later, gold was discovered in Sutter's Mill, near Sacramento, about 140 miles northeast of the Golden Gate. The precious metal find inspired the California Gold Rush and fueled San Francisco's rise as a major American city.

The non-native population of California grew from about 1,000 to 100,000 in 1849 alone. 

The San Francisco Bay Area today boasts a population of nearly 8 million people, making it one of the five largest metropolitan areas in the United States. 

The metro area includes Oakland to the east of the bay and San Jose to the south of the bay.

The Golden Gate Bridge forms a critical transportation viaduct for the region. The bridge is a segment of both U.S. Highway 101, the longest remaining pre-Interstate U.S. route in the nation, and California Route 1, known popularly as the Pacific Coast Highway. 

The bridge itself is a major American tourist attraction, drawing about 10 million visitors annually.

Strauss died on May 16, 1938 — just 11 days shy of the one-year anniversary of the bridge's opening to the public.

He wrote a poem in tribute to the bridge, "The Mighty Task is Done," soon after its completion. 

"On its broad decks in rightful pride/The world in swift parade shall ride/Throughout all time to be/Beneath, fleet ships from every port/vast landlocked bay, historic fort/And dwarfing all — the sea."
