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.
The Brooklyn Bridge is a hybrid cable-stayed/suspension bridge in New York City, spanning the East River between the boroughs of Manhattan and Brooklyn. Opened on May 24, 1883, the Brooklyn Bridge was the first fixed crossing of the East River. It was also the longest suspension bridge in the world at the time of its opening, with a main span of 1,595.5 feet (486.3 m) and a deck 127 ft (38.7 m) above mean high water. The span was originally called the New York and Brooklyn Bridge or the East River Bridge but was officially renamed the Brooklyn Bridge in 1915.
Othmar Hermann Ammann was a Swiss-American civil engineer whose bridge designs include the George Washington Bridge, Verrazzano-Narrows Bridge, and Bayonne Bridge. He also directed the planning and construction of the Lincoln Tunnel.
The Tacoma Narrows Bridge is a pair of twin suspension bridges that span the Tacoma Narrows strait of Puget Sound in Pierce County, Washington. The bridges connect the city of Tacoma with the Kitsap Peninsula and carry State Route 16 over the strait. Historically, the name "Tacoma Narrows Bridge" has applied to the original bridge, nicknamed "Galloping Gertie", which opened in July 1940 but collapsed possibly because of aeroelastic flutter four months later, as well as to the successor of that bridge, which opened in 1950 and still stands today as the westbound lanes of the present-day two-bridge complex.
John Augustus Roebling was a German-born American civil engineer. He designed and built wire rope suspension bridges, in particular the Brooklyn Bridge, which has been designated as a National Historic Landmark and a National Historic Civil Engineering Landmark.
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 1940 Tacoma Narrows Bridge, the first bridge at this location, was a suspension bridge in the U.S. state of Washington that spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7 of the same year. The bridge's collapse has been described as "spectacular" and in subsequent decades "has attracted the attention of engineers, physicists, and mathematicians". Throughout its short existence, it was the world's third-longest suspension bridge by main span, behind the Golden Gate Bridge and the George Washington Bridge.
The St. Johns Bridge is a steel suspension bridge that spans the Willamette River in Portland, Oregon, United States, between the Cathedral Park neighborhood in North Portland and the Linnton and Northwest Industrial neighborhoods in Northwest Portland. It carries the U.S. Route 30 Bypass. It is the only suspension bridge in the Willamette Valley and one of three public highway suspension bridges in Oregon.
The Bronx–Whitestone Bridge is a suspension bridge in New York City, carrying six lanes of Interstate 678 over the East River. The bridge connects Throggs Neck and Ferry Point Park in the Bronx, on the East River's northern shore, with the Whitestone neighborhood of Queens on the southern shore.
The Bear Mountain Bridge, ceremonially named the Purple Heart Veterans Memorial Bridge, is a toll suspension bridge in New York State. It carries US 6 and US 202 across the Hudson River between Bear Mountain State Park in Orange County and Cortlandt in Westchester County. At completion in 1924 it was the longest suspension bridge in the world until this record was surpassed 19 months later by the Benjamin Franklin Bridge between Philadelphia and Camden, New Jersey. Like the Williamsburg Bridge in New York City, the approach spans of the Bear Mountain Bridge are unsuspended; only its main span is suspended by cables.
The Franklin Delano Roosevelt Mid-Hudson Bridge is a toll suspension bridge which carries US 44 and NY 55 across the Hudson River between Poughkeepsie and Highland in the state of New York.
The Waldo–Hancock Bridge was the first long-span suspension bridge erected in Maine, as well as the first permanent bridge across the Penobscot River downstream from Bangor. The name comes from connecting Waldo and Hancock counties. The bridge was built in 1931 and retired in 2006, when the new Penobscot Narrows Bridge was opened just a few yards away. Demolition of the structure was completed by 2013.
The Rama VIII Bridge is a cable-stayed bridge crossing the Chao Phraya River in Bangkok, Thailand. It was built to alleviate traffic congestion on the nearby Phra Pinklao Bridge. Construction of the bridge took place from 1999 to 2002. The bridge was opened on 7 May 2002 and inaugurated on 20 September, the birth anniversary of the late King Ananda Mahidol, after whom it is named. The bridge has an asymmetrical design, with a single pylon in an inverted Y shape on the west bank of the river. Its eighty-four cables are arranged in pairs on the side of the main span and in a single row on the other. The bridge has a main span of 300 metres (980 ft), and was one of the world's largest asymmetrical cable-stayed bridges at the time of its completion.
The Androscoggin Swinging Bridge is a pedestrian suspension bridge spanning the Androscoggin River in Maine between the towns of Topsham in Sagadahoc County and Brunswick in Cumberland County. The bridge was built in 1892 as a timesaving approach for employees of the Cabot Manufacturing Company of Brunswick, could have safer and easier passage across the river.
The Taizhou Yangtze River Bridge is a bridge complex over the Lower Yangtze River in Jiangsu Province in eastern China. The bridge connects Taizhou on the north bank, Yangzhong on an island in the river, and Yaoqiao Village of Zhenjiang Municipality on the south bank, and consists of a suspension bridge across the north branch stream and a pair of box-girder bridges across the south branch stream. Taizhou Bridge Complex opened in 2012.
The Black Suspension Bridge spans the Colorado River in the inner canyon of Grand Canyon National Park. The span length is 440 feet (130 m). The bridge is part of the South Kaibab Trail and is the river crossing used by mules going to Phantom Ranch. The Black Bridge and Silver Bridge, located about 700 metres (2,300 ft) downstream, are the only spans in hundreds of river miles.
