the ‘riberas de loyola footbridge’ designed by spanish firm anta ingenieria civil crosses a span of over 73 meters without intermediate supports. gently curving over the river urumea in san sebastian in spain, the bridge connects a new urban area with a historic city park. the attachments to these two distinct banks are distinguished through the shape of the structure – the side of cristina enea park features a flat vertical surface, while the side of riberas de loyola consists of a more curved, warped platform, with the intersection of the two generating a parabolic shape. the crossing was designed to be simple in its assembly and no temporary supports were placed in the river. the curved elevation and the morphology of the abutments help to reinforce its appearance of emerging from the ground.
