alluring pedestrians onto a new urban promenade, brazilian architecture firm JBMC have proposed a tube-shaped structure for the meadows salford bridge competition. the project combines both a functional crossing with an iconic landmark, from the chapel street corridor a triangular paved square frames its shiny opening. an outer copper skin resembles the hull of a ship as it gently curves along the river, helping to blur the boundary between the structure’s interior and exterior. the journey along the rotating form offers a series of changing views that gradually reveal the surrounding environment – the irwell river, the dense woodland and the meadows. to enhance this changing perspective the floor widens, reaching it widest point in the middle with 360 views over the landscape. this organic progression across the river helps to connect two distinct environments. upon reaching the other side, a smoothly sloping plateau drops towards the meadow – a welcoming introduction to the new landscape.

the structural design is based on traditional naval construction, it applies a longitudinal keel and transverse frames. the use of helical bracing, with two opposing helical halves provides a level of stability that follows the varying height. materials were chosen in regards to their simplicity, the use of prefabricated steel elements can easily be assembled on-site. locally sourced, reforested treated wooden planks are placed on the internal deck floor, these adjust to the natural curvature of the bridge. finally, the changing colors of the copper skin help to blend the urban surroundings with the green landscape.
