Context_1 : The 25 de Abril Bridge "(Ponte 25 de Abril", 25th of April Bridge, ] ) is a suspension bridge connecting the city of Lisbon, capital of Portugal, to the municipality of Almada on the left (south) bank of the Tagus river. It was inaugurated on August 6, 1966, and a train platform was added in 1999. Because it is a suspension bridge and has similar coloring, it is often compared to the Golden Gate Bridge in San Francisco, US. It was built by the American Bridge Company which constructed the San Francisco–Oakland Bay Bridge, but not the Golden Gate. With a total length of 2,277 m, it is the 27th largest suspension bridge in the world. The upper deck carries six car lanes, while the lower deck carries two train tracks electrified at 25 kV AC. Until 1974, the bridge was named "Salazar Bridge". The name "25 de Abril" commemorates the Carnation Revolution. Context_2 : Tower Bridge is a combined bascule and suspension bridge in London built between 1886 and 1894. The bridge crosses the River Thames close to the Tower of London and has become an iconic symbol of London, resulting in it sometimes being confused with London Bridge, situated some 0.5 mi upstream. Tower Bridge is one of five London bridges now owned and maintained by the Bridge House Estates, a charitable trust overseen by the City of London Corporation. It is the only one of the Trust's bridges not to connect the City of London directly to the Southwark bank, as its northern landfall is in Tower Hamlets. Context_3 : The Vincent Thomas Bridge is a 1500 ft -long suspension bridge, crossing the Los Angeles Harbor in the U.S. state of California, linking San Pedro, Los Angeles, with Terminal Island. 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. Context_4 : The Niagara Falls Suspension Bridge, which stood from 1855 to 1897 across the Niagara River, was the world's first working railway suspension bridge. It spanned 825 ft and stood 2.5 mi downstream of Niagara Falls, where it connected Niagara Falls, Ontario, to Niagara Falls, New York. Trains used the upper of its two decks, pedestrians and carriages the lower. The brainchild of Canadian politicians, the bridge was built by one American and one Canadian company. It was most commonly called the Suspension Bridge; other names included Niagara Railway Suspension Bridge, Niagara Suspension Bridge, and its official American name, the International Suspension Bridge. Context_5 : An underspanned suspension bridge (also upper deck suspension bridge) is a rare type of suspension bridge that was developed in the early 19th century. It differs from its ancestor, the simple suspension bridge, in that the deck is raised on posts above the main cables. The raised deck is less stable than a deck laid on or hung below the cables, and very few underspanned suspension bridges have been built. Examples include Guillaume Henri Dufour's Pont des Bergues (1834); and James Smith’s Micklewood Bridge. Similar bridges were proposed by Robert Stevenson in 1820 for a bridge over the River Almond between Edinburgh and Queensferry, and by a Mr. Armstrong for a bridge at Clifton. Part of the roadway on the land side of the piers of the Hammersmith Bridge was constructed in this manner. In the late 19th century and into the 20th century a few bridges of this type were constructed. Context_6 : The Wheeling Suspension Bridge is a suspension bridge spanning the main channel of the Ohio River at Wheeling, West Virginia. It was the largest suspension bridge in the world from 1849 until 1851. Charles Ellet Jr. (who also worked on the Niagara Falls Suspension Bridge) built it, and it became the first bridge to span a major river west of the Appalachian mountains. It linked the eastern and western section of the National Road, and became especially strategically important during the American Civil War. Litigation in the United States Supreme Court concerning its obstruction of the new high steamboat smokestacks eventually cleared the way for other bridges, especially needed by expanding railroads. Because this bridge was designed during the horse-and-buggy era, 2-ton weight limits and vehicle separation requirements now apply. Context_7 : More London, also named London Bridge City, is a privately owned development on the south bank of the River Thames, immediately south-west of Tower Bridge in London. The southern exit is on Tooley Street. Context_8 : The Union Bridge, also known as the Union Suspension Bridge or Union Chain Bridge, is a suspension bridge that spans the River Tweed between Horncliffe, Northumberland, England and Fishwick, Berwickshire, Scotland. In so doing it also spans the border between England and Scotland. When it opened in 1820 it was the longest wrought iron suspension bridge in the world with a span of 137 m , and the first vehicular bridge of its type in the United Kingdom. Although work started on the Menai Suspension Bridge first, the Union Bridge was completed earlier. Today it is the oldest suspension bridge still carrying road traffic and is a Category A listed building in Scotland and a Grade I listed building in England. It lies on Sustrans Route 1 and the Pennine Cycleway. Context_9 : The 1950 Tacoma Narrows Bridge is a suspension bridge in the U.S. state of Washington that carries the westbound lanes of Washington State Route 16 (known as Primary State Highway 14 until 1964) across the Tacoma Narrows strait, between the city of Tacoma and the Kitsap Peninsula. Opened on October 14, 1950, it was built in the same location as the original Tacoma Narrows Bridge, which collapsed due to a windstorm on November 7, 1940. It is the older of the twin bridges that make up the Tacoma Narrows Bridge crossing of the Tacoma Narrows, and carried both directions of traffic across the strait until 2007. At the time of its construction, the bridge was, like its predecessor, the third-longest suspension bridge in the world in terms of main span length, behind the Golden Gate Bridge and George Washington Bridge; it is now the 31st longest suspension bridge in the world. Context_10 : A suspension bridge is any type of bridge that makes significant use of tension rather than or in addition to compression. A suspension bridge usually has main cables (else ropes or chains), anchored at each end of the bridge. Any load applied to the bridge is transformed into a tension in these main cables. The earliest suspension bridges had the cables anchored in the ground at either end of the bridge, but some modern suspension bridges anchor the cables to the ends of the bridge itself. The earliest suspension bridges had no towers or piers, but these are present in the majority of larger suspension bridges. Although the earlier types of suspension bridges are suitable only for relatively short spans, all of the 14 longest bridges in the world are suspension bridges (see List of longest suspension bridge spans). Ignoring the possibility of pre-Columbian trans-oceanic contact, there were two independent inventions of the suspension bridge, in Eurasia (probably in China) and in Central and South America. fact_1 : More London, also named London Bridge City, is a privately owned development on the south bank of the River Thames, immediately south-west of Tower Bridge in London. fact_2 : Tower Bridge is a combined bascule and suspension bridge in London built between 1886 and 1894. Question: When was the suspension bridge which  More London was  immediately south-west of built  
Output: between 1886 and 1894.
