The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the one-mile-wide (1.6 km) strait connecting San Francisco Bay and the Pacific Ocean in California, United States. The structure links San Francisco—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. Recognized by the American Society of Civil Engineers as one of the Wonders of the Modern World, the bridge is one of the most internationally recognized symbols of San Francisco and California.
A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world.
A cable-stayed bridge has one or more towers, from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly.
The San Francisco–Oakland Bay Bridge, commonly referred to as the Bay Bridge, is a complex of bridges spanning San Francisco Bay in California. As part of Interstate 80 and the direct road between San Francisco and Oakland, it carries about 260,000 vehicles a day on its two decks. It includes one of the longest bridge spans in the United States.
The Steel Bridge is a through truss, double-deck vertical-lift bridge across the Willamette River in Portland, Oregon, United States, opened in 1912. Its lower deck carries railroad and bicycle/pedestrian traffic, while the upper deck carries road traffic, and light rail (MAX), making the bridge one of the most multimodal in the world. It is the only double-deck bridge with independent lifts in the world and the second oldest vertical-lift bridge in North America, after the nearby Hawthorne Bridge. The bridge links the Rose Quarter and Lloyd District in the east to Old Town Chinatown neighborhood in the west.
Interstate 805 (I-805) is a major north–south auxiliary Interstate Highway in Southern California. It is a bypass auxiliary route of I-5, running roughly through the center of the Greater San Diego region from San Ysidro near the Mexico–U.S. border to near Del Mar. The southern terminus of I-805 at I-5 in San Ysidro is less than 1 mi (1.6 km) north of the Mexican border. I-805 then traverses the cities of Chula Vista and National City before reentering San Diego. The freeway passes through the San Diego neighborhoods of North Park, Mission Valley, Clairemont, and University City before terminating at I-5 in the Sorrento Valley neighborhood near the Del Mar city limit.
The Royal Alexandra Interprovincial Bridge, also known as the Alexandra Bridge or Interprovincial Bridge, is a steel truss cantilever bridge spanning the Ottawa River between Ottawa, Ontario and Gatineau, Quebec. In addition to carrying vehicle traffic, a shared use pathway on the bridge for pedestrians and cyclists is maintained by the National Capital Commission.
The Waco Suspension Bridge crosses the Brazos River in Waco, Texas. It is a single-span suspension bridge, with a main span of 475 ft. Opened on November 20, 1869, it contains nearly 3 million bricks. It is located north of downtown Waco, connecting Indian Spring Park with Doris D. Miller Park. Every year on Independence Day, the bridge serves as a place where thousands of locals gather to watch fireworks. Indian Spring Park marks the location of the origin of the town of Waco, where the Huaco Indians had settled on the bank of the river, at the location of a cold spring.
Queens Boulevard is a major thoroughfare connecting Midtown Manhattan, via the Queensboro Bridge, to Jamaica in Queens, New York City, United States. It is 7.5 miles (12.1 km) long and forms part of New York State Route 25.
A simple suspension bridge is a primitive type of bridge in which the deck of the bridge lies on two parallel load-bearing cables that are anchored at either end. They have no towers or piers. The cables follow a shallow downward catenary arc which moves in response to dynamic loads on the bridge deck.
The San Diego–Coronado Bridge, commonly referred to as the Coronado Bridge, is a prestressed concrete/steel girder fixed-link bridge crossing over San Diego Bay, linking San Diego with Coronado, California. It is signed as part of State Route 75.
The Vincent Thomas Bridge is a 1,500-foot-long (460 m) suspension bridge, crossing 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. Its chief engineer was William "Jim" Jurkovich who was instrumental in bringing pre-stress concrete bridge design to California. 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 feet (56 m); it is the only suspension bridge in the world supported entirely on piles.
The Howrah Bridge is a balanced steel bridge over the Hooghly River in West Bengal, India. Commissioned in 1943, the bridge was originally named the New Howrah Bridge, because it replaced a pontoon bridge at the same location linking the both sides of cities of Kolkata. Burrabazar is connected with Howrah rail terminal because of this bridge. On 14 June 1965, it was renamed Rabindra Setu after the Bengali poet Rabindranath Tagore, who was the first Indian and Asian Nobel laureate. It is still popularly known as the Howrah Bridge.
The eastern span replacement of the San Francisco–Oakland Bay Bridge was a construction project to replace a seismically unsound portion of the Bay Bridge with a new self-anchored suspension bridge (SAS) and a pair of viaducts. The bridge is in the U.S. state of California and crosses the San Francisco Bay between Yerba Buena Island and Oakland. The span replacement took place between 2002 and 2013, and is the most expensive public works project in California history, with a final price tag of $6.5 billion, a 2,500% increase from the original estimate of $250 million, which was an initial estimate for a seismic retrofit of the span, not the full span replacement ultimately completed. Originally scheduled to open in 2007, several problems delayed the opening until September 2, 2013. With a width of 258.33 ft (78.74 m), comprising 10 general-purpose lanes, it is the world's widest bridge according to Guinness World Records.
The Cabrillo Bridge is a historic bridge in San Diego, California, providing pedestrian and light automotive access between Balboa Park and the uptown area of San Diego. It was built for the Panama–California Exposition of 1915. The bridge was nominated for the National Register of Historic Places in 1976 and was named a Local Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1986.
The South Tenth Street Bridge, most often called the Tenth Street Bridge, but officially dubbed the Philip Murray Bridge, is a suspension bridge that spans the Monongahela River in Downtown Pittsburgh, Pennsylvania.
Krymsky Bridge is a steel suspension bridge in Moscow. The bridge spans the Moskva River 1,800 metres south-west from the Kremlin and carries the Garden Ring across the river.

The BP Pedestrian Bridge, or simply BP Bridge, is a girder footbridge in the Loop community area of Chicago, United States. It spans Columbus Drive to connect Maggie Daley Park with Millennium Park, both parts of the larger Grant Park. Designed by Pritzker Prize-winning architect Frank Gehry and structurally engineered by Skidmore, Owings and Merrill, it opened along with the rest of Millennium Park on July 16, 2004. Gehry had been courted by the city to design the bridge and the neighboring Jay Pritzker Pavilion, and eventually agreed to do so after the Pritzker family funded the Pavilion.
The James D. Pfluger Pedestrian and Bicycle Bridge is a shared use bridge for pedestrians and cyclists spanning Lady Bird Lake in downtown Austin, Texas. Opened in 2001, the bridge connects the north and south sides of the Ann and Roy Butler Hike-and-Bike Trail and features an unusual "double curve" design. The bridge runs parallel to the Lamar Boulevard Bridge, which carries road traffic across the lake roughly 200 feet (61 m) to the west.
