Butterflies’ Bridge

In Buenos Aires city the Butterflies’ Bridge is a respectful intervention on the past, proposing a sustainable everyday singular scenario, with a hopeful speech of a better livable city. Where from both sides of the river is linked by pedestrian people, strengthening social ties, local identity and extend that biodiversity.

In Buenos Aires city there is an inner river that is being restored, after many decades of pollution and urban decay, called Riachuelo. There used to be an industrial area and then it went down on abandonment being waged in the last quarter of the twentieth century. All bridges that cross it are remains of railways and automotives, where some of them allow the passing of pedestrians. But it is not exclusively a pedestrian bridge.
In this urban space that is being recovered from degradation, a new landscape will be forming in parallel with environmental improvement. In this context it is proposed to take one of those vehicular bridges and transform it into a pedestrian one, so singularly accompanying the weighting of the new stream, margins and urban environment.
The bridge that was chosen is the one with less traffic flow, called Bosch and was opened in 1908. It has a patrimonial value, metallic on brick columns on the river. Within walking distance of one of his hits, in the neighborhood of Barracas, it is the Centro Metropolitano de Diseño (Metropolitan Design Center), of the Government of the City of Buenos Aires, and the other access on Municipality of Avellaneda, sight and almost over the river, is the headquarters of the Facultad de Ciencias Ambientales de la Universidad Nacional de Avellaneda (School of Environmental Sciences at the National University of Avellaneda). Both are recycled old buildings of the activities that the area had and are now landmarks of the transformation underway.
In this institutional context and with an urban environment renewal, it is proposed not only to recycle the vehicular pedestrian bridge, but also to produce a new space to provide a new landscape, yet closely linked to the lost original landscape. A covered bridge of native vegetation, which almost does not remain in the city and that brings to the environmental restoration not only for its original image, but also because especially attractors and host plant species of butterflies are chosen aims. Native butterflies also limited in its current presence, but for which we can find dozens of different species, if the environment is favorable. They also convened turn birds feed or its butterfly and caterpillars. Creating a space for biodiversity hand to the passersby.
Crossing this bridge surrounded by flowery vegetation and accompanied by the flight of varied butterflies and birds with their trills, from where you can appreciate the view of the river on the river itself, in a quiet space, appeased, contemplative and even educational, because it offers getting to know native flora and fauna of a lost landscape, understanding the ecological interactions that are essential for the functioning of an ecosystem that supports a naturalized landscape.
Butterflies’ Bridge is a respectful intervention on the past, proposing a sustainable, possible everyday scenario, with a hopeful speech of a better, livable city. Where from both sides of the river is linked by pedestrian people, strengthening social ties, local identity and since then the bridge can extend that biodiversity makes public and private spaces of the adjoining neighborhoods. Where in the margins of both bridgeheads, these public spaces with native vegetation of larger size, such as trees and shrubs, which prevents the lack of substrate planting on the bridge are populated. Thus strengthening biodiversity space focused on the bridge, as a cohesive element.
Butterflies are one of the elements we value most pleasantly of nature, its colors, subtlety and surprise types of flight, which is perceived as a contribution to improving the quality of the landscape, so that the inhabitants of that landscape linking more and better with the space they inhabit, to strengthen the collective commitment to public space.
