Title: Golden Gate
Content:   The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the opening of the San Francisco Bay onto the Pacific Ocean. As part of both US Highway 101 and California Route 1, it connects the city of San Francisco on the northern tip of the San Francisco Peninsula to Marin County. The Golden Gate Bridge was the longest suspension bridge span in the world when completed in 1937, and is an internationally recognized symbol of San Francisco and California in general. Since its completion 85.51127516996448 years ago, the span length has been surpassed by eight other bridges. It is the second longest suspension bridge main span in the United States, after the Verrazzano-Narrows Bridge (1964) in New York City. In 2007, it was ranked fifth on the List of America's Favorite Architecture by the American Institute of Architects.
Title: Golden Gate Bridge
Content:  The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the 1 mi strait connecting San Francisco Bay and the Pacific Ocean. The structure links the U.S. city of San Francisco, California—the northern tip of the San Francisco Peninsula—to Marin County, carrying both U.S. Route 101 and California State Route 1 across the strait. It also carries pedestrian and bicycle traffic, and is designated as part of U.S. Bicycle Route 95. Being declared one of the Wonders of the Modern World by the American Society of Civil Engineers, the bridge is one of the most internationally recognized symbols of San Francisco and California. It was initially designed by engineer Joseph Strauss in 1917. The Frommer's travel guide describes the Golden Gate Bridge as "possibly the most beautiful, certainly the most photographed, bridge in the world." At the time of its opening in 1937, it was both the longest and the tallest suspension bridge in the world, with a main span of 4,200 ft and a total height of 746 ft.

Includes an active subway line and never-used trolley stations on the span. ; San Francisco–Oakland Bay Bridge (USA, 1936). This was once the longest steel high-level bridge in the world (704 m). The eastern portion (a cantilever bridge) has been replaced with a self-anchored suspension bridge which is the longest of its type in the world. It is also the world's widest bridge. ; Golden Gate Bridge (USA, 1937), the longest suspension bridge from 1937 to 1964. It was also 
Title: 25 de Abril Bridge
Content:   The 25 de Abril Bridge is based in part on two San Francisco Bay Area bridges. Its paint is the same International Orange color as the famous Golden Gate Bridge, and its design is similar to that of the San Francisco–Oakland Bay Bridge. Both the Bay Bridge and the 25 de Abril Bridge were built by the same company. The American Society of Civil Engineers says: "Like its sister bridge, the SFOBB in San Francisco, the Tagus River Bridge is located in an area with a long history of earthquakes" and seismic data had to be taken into account in its construction. Another sister bridge is the Forth Road Bridge in Edinburgh. Upon completion, the bridge had the longest suspended span and the longest main span in Continental Europe, the world's longest continuous truss, and the world's deepest bridge foundation. It was the fifth-largest suspension bridge in the world, and the largest outside the US. Today it is the 43rd largest suspension bridge in the world.
Title: Vincent Thomas Bridge
Content:  The Vincent Thomas Bridge is a 1500 feet suspension bridge, crossing the Los Angeles Harbor in Los Angeles, California, linking San Pedro with Terminal Island. It is the only suspension bridge in the Greater Los Angeles area. The bridge is part of State Route 47, which is also known as the Seaside Freeway. The bridge opened in 1963 and is named for California Assemblyman Vincent Thomas of San Pedro, who championed its construction. It was the first welded suspension bridge in the United States and is now the fourth-longest suspension bridge in California and the 76th-longest span in the world. The clear height of the navigation channel is approximately 185 ft; it is the only suspension bridge in the world supported entirely on piles.

It spans the Golden Gate, the strait between San Francisco and Marin County, and is the only bridge in the area not owned by the State of California. ; The San Francisco–Oakland Bay Bridge on I-80 connects Alameda and San Francisco counties. ; The San Mateo–Hayward Bridge on SR 92 connects Alameda and San Mateo counties. ; 
Title: Mackinac Bridge
Content:  The bridge opened on November 1, 1957, connecting two peninsulas linked for decades by ferries. At the time, the bridge was formally dedicated as the "world's longest suspension bridge between anchorages", allowing a superlative comparison to the Golden Gate Bridge, which has a longer center span between towers, and the San Francisco–Oakland Bay Bridge, which has an anchorage in the middle. It remains the longest suspension bridge with two towers between anchorages in the Western Hemisphere. Much longer anchorage-to-anchorage spans have been built in the Eastern Hemisphere, including the Akashi Kaikyō Bridge in Japan (6532 ft), but the long leadups to the anchorages on the Mackinac make its total shoreline-to-shoreline length of 5 mi longer than the Akashi Kaikyo (2.4 mi). The length of the bridge's main span is 3800 ft, which makes it the third-longest suspension span in the United States and 20th longest suspension span worldwide. It is also one of the world's longest bridges overall.

One of the state's more visible landmarks, the Golden Gate Bridge, was the longest suspension bridge main span in the world at 4200 ft between 1937 (when it opened) and 1964. With its orange paint and panoramic views of the bay, this highway bridge is a popular tourist attraction and also accommodates pedestrians and bicyclists. The San Francisco–Oakland Bay Bridge (often abbreviated the "Bay Bridge"), completed in 1936, transports about 280,000 vehicles per day on two-decks.

Before opening the bridge was blessed by Cardinal Secretary of State Eugene Cardinal Pacelli, later Pope Pius XII. Because it was in effect two bridges strung together, the western spans were ranked the second and third largest suspension bridges. Only the George Washington Bridge had a longer span between towers. As part of the celebration a United States commemorative coin was produced by the San Francisco Mint. A half dollar, the obverse portrays California's symbol, the grizzly bear, while the reverse presents a picture of the bridge spanning the bay. A total of 71,369 coins were sold, some from the bridge's tollbooths.
