The architects found their inspiration in the history of the area in the first half of the twentieth century. It was the proverbial urban fringe, where people took walks and boys from the city went fishing, while picknicks were enjoyed beside the Zuidelijke Wandelweg. It was here that the first football clubs had their pitches and the circus set up its tents when it came to town. In other words, the area was a combination of a traditional agrarian landscape, as depicted by Rembrandt in his drawings, and a green environment for recreation. Its core function was to provide both a sense of space and pleasurable experiences, to relieve some of the stress of urban living in the industrial age.
It was with this in mind that the design for the corridor with its road tunnel, new urban square and station emerged. The aim was to provide as much green space, peace, openness and quality of life as possible in an environment that can easily become filled with a stress-inducing profusion of bustle, noise, buildings and traffic. The space created by covering the ring road will further contribute to a reduction in noise levels and improvements to air quality.
The area concerned is an east-west corridor between the tips of two of the famous ‘green wedges’ that reach deep into the urban environment of the city. To the west lies the Amsterdamse Bos forest and the Nieuwe Meer lake with accompanying sports pitches, to the east the green zone around the River Amstel, including the allotments of Amstelglorie, a new park called Somerlust, the Zorgvlied graveyard, the Amstelpark and, as a bonus, the Beatrixpark.
The design lines the ring road at both ends of the tunnel with rounded slopes planted with acacia and apple trees, and noise reduction screens with plants growing over them, thereby concealing the jumble of ramps and exits behind a green decor. The varied planting at the roadsides will enable this traffic zone to merge seamlessly with the Beatrixpark and sports pitches at the other end of the corridor. The space is of necessity divided into separate levels for trains, trams, cars and pedestrians, and the resulting landscape will be used to the full, in combination with green roofs, flowerbeds and shrubbery, to create the impression of a park.
