Water plays a key role in the plans for the expansion area IJburg. In view of its location in the open water of IJmeer, it was decided to bring the element water and the experience of water to street level. IJburg has a high building density, as a result of which considerable attention has been given to the quality of the public space. In many areas, the urban designers have opted for blue (canals, watercourses, harbours) rather than green (parks, gardens and flowerbeds). Public life therefore often takes place on the inner canals, the quays and IJmeer. The requirements of water control and the accessibility of the islands, together with the focus on water in the design, have resulted in the construction of a large number of bridges, locks and other structural works. In order to preserve an overview of all these works and to create unity, the bridges and locks in the first phase of IJburgs construction have been divided into five families. Each family has its own formal idiom, which is in keeping with its function and surroundings.
IJburgs main bridges are situated in open outer water and connect the islands to each other and to the city. They form part of the main infrastructure for cars, bicycles and the tram. Grimshaw & Partners, who also designed the Ennëus Heermabrug and Brug 2002, is responsible for the design of the family Hoofdbruggen (main bridges), also known as Eilandbruggen (island bridges). Quist Wintermans architects designed the bridge family De Lange Lijn (the long line). IJburgs main eastern connection with the motorways A1/A9 follows a long route through a green and tranquil rural area. The design is low-key and unobtrusive in the landscape. Nesciobrug, a cycle and pedestrian bridge over the Amsterdam-Rhine Canal, designed by Jim Eyre, is part of this family.
The Binnengracht (inner canal) family is in keeping with the stony, compact development on Haveneiland. Erna van Sambeek designed brick abutments and steel spans. The black steel bridges by the architect Birgit Rapp, with high walls that separate the pedestrian section from the cyclists and car section, are reminiscent of industrial railway bridges. The architects Roberto Meyer and Jeroen van Schooten have given expression to the marked transition between the urban Haveneiland West and the green living environment on Grote Rieteiland in the design of the bridge family De Groen Tunnel (the green tunnel). The bridges located on the edges of the islands are the lightest and most transparent of all the bridges. These form part of the family Buitenwater (outer water) and were designed by Jan Benthem.
