The Pont Charles-de-Gaulle (Charles-de-Gaulle Bridge) is a steel-reinforced concrete girder bridge straddling the river Seine in the eastern part of Paris. It is a one-way bridge carrying road traffic from the 13th arrondissement to the 12th arrondissement. Further downstream, also a one-way bridge, Pont d’Austerlitz carries traffic travelling in the opposite direction.
In 1986, the Council of Paris (Conseil de Paris) decided to construct a new bridge between Pont de Bercy and Pont d’Austerlitz in south-west Paris, which would imitate the design of Pont d’Austerlitz. The aims of this project were to ease the traffic on Pont d’Austerlitz, the most heavily loaded bridge in the capital, to connect the new Bibliothèque nationale de France (also known as the François Mitterrand Library) to the district of Bercy on the Right Bank and to establish a direct link between Gare de Lyon and Gare d’Austerlitz.
A Europe-wide competition was held in 1987 to determine the best project design. At the conclusion of the competition, the laureate concept set forth by Louis Arretche and Roman Karasinski was chosen for the bridge. The rationale for this choice was that it did not detract the aesthetic exterior of Viaduc d’Austerlitz, further downstream; and that it discreetly preserved the view of the river.
The bridge has a single steel deck measuring 270 m long and 35 m wide, and the shape of which resembles an aircraft wing. It is supported by two concrete piers. Linking each pier to the deck are two conical steel frames shaped like upside-down tents.
The bridge roadway (not including footpaths and cycle lanes) measures 18 m in width and allows four lanes of northeast-bound traffic from the Left Bank to the Right Bank. Two cycle lanes to the upstream side of the bridge and two footpaths, one on each side of it, permit unmotorized traffic to cross.

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.

Tour Sequoia (previously known as tour Bull, and also known as tour SFR or tour Cegetel) is an office skyscraper located in La Défense business district just west of Paris, France.
Built in 1990, that 119 meter-tall tower represents the transition between the third and the fourth generation of buildings in La Défense. It’s been the first tower to be built with a semi-circular design in the business district. Later, that design will inspire other towers such as CBC, Kupka, Pacific, Société Générale twin towers or Tour CBX. Tour Sequoia has been built in proximity with the CNIT and the Grande Arche.
