The Manhattan Bridge is a suspension bridge that crosses the East River in New York City, connecting Lower Manhattan (at Canal Street) with Brooklyn (at Flatbush Avenue Extension) on Long Island. It was the last of the three suspension bridges built across the lower East River, following the Brooklyn and the Williamsburg bridges. The bridge was opened to traffic on December 31, 1909 and was designed by Leon Moisseiff, who later designed the infamous original Tacoma Narrows Bridge that opened and collapsed in 1940. It has four vehicle lanes on the upper level (split between two roadways). The lower level has three lanes, four subway tracks, a walkway and a bikeway. The upper level, originally used for streetcars, has two lanes in each direction, and the lower level is one-way and has three lanes in peak direction. It once carried New York State Route 27 and later was planned to carry Interstate 478. No tolls are charged for motor vehicles to use the Manhattan Bridge.
The original pedestrian walkway on the south side of the bridge was reopened after sixty years in June 2001. It was also used by bicycles until late summer 2004, when a dedicated bicycle path was opened on the north side of the bridge, and again in 2007 while the bike lane was used for truck access during repairs to the lower motor roadway.
* Main span: 1,470 ft (448 m)
* Length of suspension cables: 3224 ft (983 m)
* Total length: 6,855 ft (2,089 m)
The neighborhood near the bridge on the Brooklyn side, once known as Fulton Landing has been gentrified and is called DUMBO, an acronym for Down Under the Manhattan Bridge Overpass.
The Flatiron Building, or Fuller Building as it was originally called, is located at 175 Fifth Avenue in the borough of Manhattan, and is considered to be one of the first skyscrapers ever built. Upon completion in 1902 it was one of the tallest buildings in New York City. The building sits on a triangular island block at 23rd Street, Fifth Avenue, and Broadway, anchoring the south (downtown) end of Madison Square.The neighborhood around the building is called the Flatiron District after its signature building, which has become an icon of New York.
The Flatiron Building was designed by Chicago’s Daniel Burnham in the Beaux-Arts style. Unlike New York’s early skyscrapers, which took the form of towers arising from a lower, blockier mass, such as the contemporary Singer Building (1902-08), the Flatiron Building epitomizes the Chicago school conception: like a classical Greek column, its limestone and glazed terra-cotta façade is divided into a base, shaft and capital. Early sketches by Daniel Burnham show a design with an (unexecuted) clockface and a far more elaborate crown than in the actual building. Burnham, though he maintained overall control of the design process, was not directly connected with the details of the structure as built; credit should be shared with his designer Frederick P. Dinkelberg (c 1859—1935), a Pennsylvania-born architect in Burnham’s office, who first worked for Burnham at the World’s Columbian Exposition, Chicago, 1893. Working drawings for the Flatiron Building, however, remain to be located, though renderings published at the time of construction in American Architect and The Architectural Record.Since it employed a steel skeleton, building to 22 stories was relatively simple. It was a technique familiar to the Fuller Company, a contracting firm based in Chicago with ties to Burnham and considerable expertise in building such tall structures.At the vertex, the triangular tower is only 6.5 feet (2 m) wide; viewed from above, this ‘pointy’ end of the structure describes an acute angle of about 25 degrees. The strong downdrafts in this area were reputed to raise women’s skirts as they passed. New York’s Flatiron Building was not the first building of its triangular ground-plan: aside from a possibly unique triangular Roman temple built on a similarly constricted site in the city of Verulam, Britannia, both the Gooderham Building of Toronto, built in 1892, and the 1897 English-American Building in Atlanta predate it. Both, however, are smaller than their New York counterpart.

La Défense is a major business district for the city of Paris. With a population of 20,844, it is centered in an oval freeway loop straddling the Hauts-de-Seine département municipalities of Nanterre, Courbevoie and Puteaux. The district is at the westernmost extremity of Paris’ 10 km long Historical Axis, which starts at the Louvre in Central Paris and continues along the Champs-Élysées, well beyond the Arc de Triomphe before culminating at La Défense.
Around its 110-metre (360 ft)-high Grande Arche and esplanade (« le Parvis »), the district holds many of the Paris urban area’s tallest high-rises. With its 77.5 acres (314,000 m2), its 72 glass-and-steel slick buildings including 14 high-rises above 150 metres (490 ft), its 150,000 daily workers and 3.5 million square metres (37.7 million sq ft) of office space, La Défense is Europe’s largest purpose-built business district.
