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 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.
The Delaware Memorial Bridge is a dual-span suspension bridge crossing the Delaware River. The toll bridges carry Interstate 295 and U.S. Route 40 and is also the link between Delaware and New Jersey. The bridge was designed by the firm of Howard, Needles, Tammen & Bergendoff with consulting help from engineer Othmar Ammann, whose other designs include the George Washington Bridge and the Verrazzano-Narrows Bridge.
The Runyang Yangtze River Bridge is a large bridge complex that crosses the Yangtze River in Jiangsu Province, China, downstream of Nanjing. The complex consists of two major bridges that link Zhenjiang on the south bank of the river and Yangzhou on the north. The bridge is part of the Yangzhou–Liyang Expressway. Construction of the bridge complex began in October 2000 and was completed ahead of schedule. The bridge cost 5.8 billion Yuan. The complex opened to traffic on April 30, 2005. The total length of the bridge complex is about 35.66 kilometres (22.16 mi). In between the two bridges is the island of Shiyezhou.
An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons deviating upward from the deck. In this concept, they remain part of the main bridge superstructure.
The Xiling Yangtze River Bridge, is a suspension bridge over the Yangtze River, just a few kilometers downstream from the Three Gorges Dam. The bridge is located within Yiling District of the prefecture-level city of Yichang, connecting the towns of Taipingxi and Letianxi with Sandouping.
The Egongyan Bridge is a suspension bridge which crosses the Yangtze River in Chongqing, China. Completed in 2000, it has a main span of 600 metres (2,000 ft). The connects Nan'an District east of the Yangtze River with Jiulongpo District to the west. Originally, the bridge was built with to be six lanes wide with a pedestrian walkway on each side but was expanded to eight lanes in 2013. The expansion removed the walkways. Pedestrian connectivity was restored in 2019 with the opening of the Egongyan Rail Transit Bridge upstream which has a pedestrian walkway.
The Parkersburg–Belpre Bridge is a four-lane cantilever bridge that connects Parkersburg, West Virginia, to Belpre, Ohio, across the Ohio River. The bridge was completed in 1980. The bridge had been signed U.S. Route 50 (US 50) until June 13, 2008, when that highway was re-routed to the Blennerhassett Island Bridge a few miles to the west, as part of the completion of the Corridor D project around Parkersburg. The American Discovery Trail uses the bridge to cross the Ohio River.
The Shanghai Yangtze River Tunnel and Bridge is a bridge–tunnel complex across the south fork of the Yangtze River near the river mouth in Shanghai. The tunnel connects the Pudong District of Shanghai on the south bank of the river with Changxing Island, while the bridge connects Changxing Island with Chongming Island. In combination with the Chongqi Bridge, which connects Chongming Island to the north bank of the Yangtze, the bridge–tunnel complex forms the final crossing of the Yangtze before it empties into the East China Sea.
The Benjamin Franklin Bridge, originally named the Delaware River Bridge and known locally as the Ben Franklin Bridge, is a suspension bridge across the Delaware River connecting Philadelphia, Pennsylvania, and Camden, New Jersey. Owned and operated by the Delaware River Port Authority, it is one of four primary vehicular bridges between Philadelphia and southern New Jersey, along with the Betsy Ross, Walt Whitman, and Tacony-Palmyra bridges. It carries Interstate 676/U.S. Route 30, pedestrians/cyclists, and the PATCO Speedline.
The bridges and tunnels across the Yangtze River carry rail and road traffic across China's longest and largest river and form a vital part of the country's transportation infrastructure. The river bisects China proper from west to east, and every major north–south bound highway and railway must cross the Yangtze. Large urban centers along the river such as Chongqing, Wuhan, and Nanjing also have urban mass transit rail lines crossing the Yangtze.
The Chaotianmen Bridge, is a road-rail bridge over the Yangtze River in the city of Chongqing, China. The bridge, which opened on 29 April 2009, is the world's longest through arch bridge.
The Jiangyin Yangtze River Bridge is a suspension bridge over the Yangtze River in Jiangsu, China. The bridge has a main span of 1,385 metres (4,544 ft) connects Jiangyin south of the river to Jingjiang to the north. When the bridge was completed in 1999, it was the fourth longest suspension bridge span in the world and the longest in China. Several longer bridges have since been completed in China and abroad, and it is currently the 15th longest suspension bridge in the world. The bridge was also the furthest downstream on the Yangtze until the completion of the Sutong Yangtze River Bridge in 2008 and the Chongming–Qidong Yangtze River Bridge in 2011.
The Nanjing Qixiashan Yangtze River Bridge, formerly Fourth Nanjing Yangtze Bridge, is a suspension bridge over the Yangtze River in Nanjing, China. The bridge is the 11th longest span in the world and the sixth largest in China. The bridge has renamed on 20 December 2019.
The Dongshuimen Bridge and the Qiansimen Bridge, known collectively as the Twin River Bridges, are a pair of bridges that form a road and rail connection in Chongqing, China. Consisting of two cable-stayed bridges and a tunnel across the Yuzhong peninsula where the heart of Chongqing's commercial & financial district Jiefangbei CBD is located, the connection opened in 2014.
