The Tower Bridge stands over the River Thames in London and is one of the world’s most recognisable bridges in the world.   One of the most famous examples of the bascule type is the Tower Bridge, which spans the River Thames just below London Bridge. It is the most distinctive of London’s bridges and its construction was a masterly engineering achievement.  Engineers were able to build this type of bridge without interrupting traffic on the great commercial waterway.


Westminster Bridge is a road and foot traffic bridge over the River Thames between Westminger and Lambeth.This bridge was esteemed one of the most complete and elegant structures of the kind in the world. It is built entirely of stone, and extends over the river at a place where it is 1,223 feet broad, which is above 300 feet broader than at London Bridge. On each side is a fine balustrade of stone, with places of shelter from the rain. The width of the bridge is 44 feet, having on each side a fine Footway for passengers. It consisting of fourteen piers, and thirteen large and two small arches, all semicircular, that in the centre being 76 feet wide, and the rest decreasing four feet each from the other; so that the two last arches of the thirteen great ones are each 52 feet. It is computed that 40,000l. value in stone and other materials is always under water.



The Bosphorus or Bosporus , also known as the Istanbul Strait , is a strait that forms part of the boundary between the European part of Turkey  and its Asian part . It is one of the Turkish Straits, along with the Dardanelles. The world’s narrowest strait used for international navigation, it connects the Black Sea with the Sea of Marmara (which is connected by the Dardanelles to the Aegean Sea, and thereby to the Mediterranean Sea). It is approximately 30 km (19 mi) long, with a maximum width of 3,700 m (12,139 ft) at the northern entrance, and a minimum width of 700 m (2,297 ft) between Kandilli and A?iyan; and 750 m (2,461 ft) between Anadoluhisar? and Rumelihisar?. The depth varies from 36 to 124 m (118 to 407 ft) in midstream. The shores of the strait are heavily populated as the city of Istanbul (with a metropolitan area in excess of 11 million inhabitants) straddles it.

The first, the Bosphorus Bridge, is 1,074 m (3,524 ft) long and was completed in 1973. The second, Fatih Sultan Mehmet (Bosphorus II) Bridge, is 1,090 m (3,576 ft) long, and was completed in 1988 about 5 km (3 mi) north of the first bridge.


The Brooklyn Bridge is one of the oldest suspension bridges in the United States. At the time it opened, it was the longest suspension bridge in the world, stretching 5,989 feet (1825 m) over the East River, connecting the New York City boroughs of Manhattan and Brooklyn. Upon completion in 1883, it was the longest suspension bridge in the world, the first steel-wire suspension bridge, and the first bridge to connect to Manhattan.

Originally referred to as the New York and Brooklyn Bridge, it was dubbed the Brooklyn Bridge in an 1867 letter to the editor of the Brooklyn Daily Eagle and formally so named by the city government in 1915. Since its opening, it has become an iconic part of the New York skyline. It was designated a National Historic Landmark in 1964.


The San-Francisco-Oakland Bay Bridge is a toll bridge which spans the San Francisco Bay and links the Californian cities of Oakland and San Francisco in the United States.

The toll bridge was conceived as early as the gold rush days, but construction did not begin until 1933. Designed by Charles H. Purcell, and built by American Bridge Company, it opened for traffic on November 12, 1936, six months before the Golden Gate Bridge. It originally carried automobile traffic on its upper deck, and trucks and trains on the lower, but after the closure of the Key System, the lower deck was converted to road traffic as well.


The Tsing Ma Bridge is a bridge in Hong Kong. It is the world’s seventh-longest span suspension bridge. The bridge was named after two of the islands at its ends, namely Tsing Yi and Ma Wan . It has two decks and carries both roadrail traffic, which also makes it the largest suspension bridge of this type. The bridge has a main span of 1,377 metres (4,518 ft) and a height of 206 metres (676 ft). The span is the largest of all bridges in the world carrying rail traffic. and

The 41 metres (135 ft) wide bridge deck carries six lanes of automobile traffic, with three lanes in each direction. The lower level contains two rail tracks. There are also two sheltered carriageways on the lower deck for maintenance access and as backup for traffic when particularly severe typhoons strike Hong Kong. Though road traffic would need to be closed in that case, trains could still get through in either direction.


Richmond Bridge is a Grade I listed 18th-century stone arch bridge in south west London, England, which crosses the River Thames at Richmond, connecting the two halves of the present-day London Borough of Richmond upon Thames. Because the river meanders from its general west to east direction, flowing from southeast to northwest in this part of London, what would otherwise be known as the north and south banks are often referred to as the “Middlesex” (Twickenham) and “Surrey” (Richmond) banks respectively, named after the historic counties to which each side once belonged.

The bridge was built between 1774 and 1777 to the designs of James Paine and Kenton Couse, as a replacement for a ferry crossing which connected Richmond town centre on the east bank with its neighbouring district of East Twickenham (St. Margarets) to the west. Its construction was privately funded by a tontine scheme, for which tolls were charged until 1859. The bridge was widened and slightly flattened in 1937–40, but otherwise still conforms to its original design. The eighth Thames bridge to be built in what is now Greater London, it is today the oldest surviving Thames bridge in London.


The Nanpu Bridge, located at the South Dock – the narrowest part of the lower reaches of the Huangpu River, was constructed in 1991. The main arch of the bridge has a span of 423 meters and a height of 46 meters. The total length of the bridge is 846 meters, and the bridge tower is 150 meters tall. Nanpu bridge is the first bridge on the Huangpu River. Tourists can take the elevator to get to the sidewalk of the bridge and overlook the scenery on both banks of the Huangpu River.
