Golden Gate Bridge Facts for Your Next Trivia Night

It all started in 1916. Or actually, it started around four decades earlier, in 1872, when railroad entrepreneur Charles Crocker called for a bridge to span the Golden Gate Strait, the 3-mile (5-kilometer) long stretch of water that connects the San Francisco Bay to the Pacific Ocean.

But it wasn't until the early 20th century that the project gained traction as the area's population grew and traffic congestion at the ferry docks was becoming a serious issue.

James H. Wilkins, a structural engineer and newspaper editor for the San Francisco Call Bulletin, connected with San Francisco City engineer Michael M. O'Shaughnessy and started talking about what it would really take to make a bridge connecting the city to the Marin Headlands a reality.

Three years later, San Francisco officials formally requested that O'Shaughnessy explore the possibility of building a strait-spanning bridge, and the engineer began consulting with colleagues around the country. Sure, the idea of connecting San Francisco to the North Bay was nice, but was it financially feasible?

Most industry insiders speculated that such an undertaking would cost over $100 million and that — perhaps more importantly — it just couldn't be built. Joseph Baermann Strauss, however, begged to differ.

Strass' Plan

Joseph Strauss, a Chicago-based engineer, presented a plan that not only made a bridge seem possible, but downright affordable: Strauss's plan estimated that the construction could be done for $25 to $30 million.

Strauss submitted his preliminary sketches to O'Shaughnessy and Edward Rainey, secretary to James Rolph, the mayor of San Francisco, on June 28, 1921.

While his original design (a $17 million symmetrical cantilever-suspension hybrid span) needed some tweaking and didn't pan out, O'Shaughnessy made the design public in December 1922, and although the press described it as "ugly," there was surprisingly little public opposition to the ambitious endeavor.

While citizens seemed relatively open to approving the massive undertaking, there were more than a few snags along the way to construction.

The Golden Gate Bridge District

First, O'Shaughnessy and Strauss had to assemble a special district of the state of California to oversee the financing, design and construction of the bridge as a way to give all counties a voice in the process. But ultimately, the fate of the bridge was in the hands of the War Department, which legally ruled all harbor construction potentially affecting shipping traffic or military logistics.

When the War Department held a hearing May 16, 1924, to discuss the bridge's potential impact on navigation and financial burden, things got thorny.

Plenty of people voiced their opposition, especially the local ferry companies who started a serious anti-bridge campaign in an effort to halt construction. And they succeeded — for eight years.

After nearly a decade of jurisdiction and uncertainty, Strauss and O'Shaughnessy were able to create the Golden Gate Bridge and Highway District (composed of the area's six member counties), incorporated by the California state legislature in 1928 as the sole entity responsible for the final design, construction and financing of the future bridge.

Construction Begins

Secretary of War Patrick Hurley issued the construction permit Aug. 11, 1930, and the building process officially kicked off nearly three years later on Jan. 5, 1933.

By this time, the vast majority of residents were stoked, and a groundbreaking ceremony at San Francisco's Crissy Field helped hype the locals for what was to be a somewhat lengthy, but easier-than-expected process.

"An interesting fact about the Golden Gate Bridge is that it was completed ahead of schedule and under budget — a rarity in today's construction world," Paolo Cosulich-Schwartz, public affairs manager for the Golden Gate Bridge, Highway & Transportation District, writes via email. "The bridge was completed in May 1937 under budget and six months ahead of schedule. It cost about $39 million to build, which equals about $500 million in today's dollars."

Not only did the bridge make a name for itself as a relatively quick and painless project (as far as massive constructions go), it also made a mark on history with its construction procedures and safety measures.

The First Safety Net for Bridge Workers

"The Golden Gate Bridge was a pioneering project for protecting workers by requiring bridge builders to wear hard hats and installing the first safety net for bridge workers," Cosulich-Schwartz says. "I'm proud that the legacy of safety lives on at the Golden Gate Bridge today."

Although 11 people died during construction (not unheard of in that risky era of building), the use of movable safety netting beneath the "floor" of the bridge during construction saved the lives of 19 people who became known as the "Halfway-to-Hell Club."

There's a reason I wanted the bridge represented in my inked hometown tribute: Aside from its significance as an instantly recognizable San Francisco staple, it's just so darn pretty. And that appealing design took a ton of thoughtful planning and dedication.

A Change of Plans

Remember Strauss' original plans for a symmetrical cantilever-suspension hybrid bridge? While his staff, led by Charles A. Ellis, found the idea to be practical from an engineering standpoint, some experts started to raise questions.

Ellis brought on Professor George F. Swain of Harvard University and Leon Moisseiff, who designed New York's Manhattan Bridge, to serve on a Board of Consultants for the project — and Moisseiff wasn't sold on the design.

On Aug. 15, 1929, the Board appointed Moisseiff, as well as engineers O.H. Ammann, and UC Berkeley engineering professor Charles Derleth Jr., to serve as the Advisory Board of Engineers, alongside Strauss.

At some point in their discussions (the exact date is unknown), the board decided to shift from Strauss' original proposal to a suspension bridge design. The Golden Gate Bridge, Report of the Chief Engineer, written by Strauss in September 1937, doesn't give details on the transition from his originally proposed design to the Moisseiff-inspired suspension span, but simply states:

There was another mysterious drama during the design process as well: While Ellis was responsible for directing the thousands of calculations required, Strauss unceremoniously fired him in 1931 and handed his job over to his assistant. To this day, Ellis is rarely mentioned in discussions of the bridge.

The Golden Gate Bridge Isn't Red

Perhaps the most recognizable feature of the bridge is its eye-popping hue — just please don't call it "red."

"International Orange is the signature color of the Golden Gate Bridge," Cosulich-Schwartz says. "The color was chosen as the primary color of the bridge by consulting architect Irving Morrow, who noticed the red lead primer of the steel arriving from mills on the east coast. He thought the red primer would serve the dual purpose of making the bridge stand out for ships and planes in the dense fog while blending in with the natural beauty of the area surrounding the bridge.

"After much study and debate, the color we so closely identify with the Golden Gate Bridge today was selected for the project, and we can thank Irving Morrow for the Golden Gate Bridge's distinctive hue."

The Bridge Today

Today, the Golden Gate Bridge is a critical transportation link between San Francisco and Marin County, and the 1.7 mile (2.7 kilometer) main span carries about 112,000 vehicles every day.

Not only can the number of vehicle traffic lanes dedicated to the southbound or northbound be modified throughout the day to accommodate shifting traffic patterns, but visitors are welcome to walk and bike the length of the landmark. Or, if you're a proud Bay Area original, get its glory permanently etched onto your skin.
