Bridges Presentation


 * == Name of bridge: Vasco da Gama Bridge ==
 * Location: located next to the site where Expo '98 stood and today stands Parque das Nações (Park of Nations). It's located on the eastern end of Lisbon which, until the beginning of the nineties, was the poor side of the capital, full of abandoned containers, garbage depots, junkyards, slaughterhouses, arms factories, refineries and gas terminals, in short, a rundown area in dire need of redevelopment. Transforming this public dump into a quality area, decontaminating 330 hectares of land and cleaning up 5 kilometers of river front took four years.
 * Type of bridge: cable-stayed bridge: the longest in Europe and one of the largest of its kind in the world
 * TOTAL LENGTH OF CROSSING: 17.2 KM
 * Materials used: reinforced concrete structure with main deck stayed to main pylons|| length of marine viaduct (9 km)
 * Length of the cable-stayed main arch: 826 m (192 cables)
 * Navigation deck clearance 47 m above water level on the North Channel
 * Purpose of the bridge: need for an alternative north-south traffic link to bypass Lisbon and reduce traffic congestion in the capital
 * BACKGROUND INFORMATION: in April of 1994, Lusoponte, a group of Portuguese, British and French companies won the international allowance to design, construct, finance and operate the new passage, the Vasco da Gama Bridge. In February of 1995 was the beginning of the construction and in March of 1998 it was opened to traffic. In 2000 it was award first prize by the Ibero-Americana Institution of Architecture and Civil Engineering.

EISENER STEG
 * Name of bridge: Eisener Steg
 * Location: Frankfurt, Germany.
 * Type of bridge: Truss Bridge
 * Materials used: Iron and Steel
 * Purpose of the bridge: The other two bridges across the Main at that time were the centuries old Alte Bruecke (Old Bridge)and a railroad bridge (today's Friedensbruecke) that was begun in 1844, and these were dangerous for people to cross by walking because of the heavy traffic. The Eisener Steg bridge was for pedestrian use only as there was no space on the Frankfurt side to build access ramps for a road bridge. It was rebuilt in 1910 because its height was too low, and then rebuilt two other times because it had been destroyed during the war.
