Given the scale of the structure, we propose the combination of arches as the most suitable solution. In reaction to the context, the angle of the river and roads with the axis of the bridges, we make the arches jumping from side to side of the deck. Since the heights of the arches are proportional to their spans, they don’t touch each other. The rotating stiffeners generate a series of virtual surfaces of double curvature, which emphasize the dynamism of the space. It is crucial to control the continuity of the arches at the ground level, and their connections with the deck, tangent and intersecting, which make the cables to alternate the alignment of their anchoring points.
The “balanced asymmetry” of the project resembles the profile of a chain of DNA, as metaphor of the vitality of the new city. From far away, the twin bridge becomes the new artificial mountain landscape of Qingpu.
西大盈港双子桥将成为今后青浦区扩展后最重要的城市地标，我们希望为这个城市贡献一个具有象征意义的建筑体，结构合理、可实施性强同时又具有前瞻性。
根据给定的规模，我们觉得采用连续的拱形结构是比较合适的方案。为了回应当地的文脉，根据河流、道路及桥体轴线的走向，我们将每个人拱都横跨桥面而设置，拱的高度与跨度成一定比例，且互不相交。旋转的刚性构件生成为一系列双曲拱的表面，为桥面空间增添了无限的活力和律动。拱和地面及桥面接触、相切或交叉时是否连续是这一工程的关键，这关系到钢索是否能顺利地在锚点线上切换。
近观，“不对称的平衡”看起来像DNA链，隐喻了这个新城的活力。远观，连续的拱梁如同延绵的山脉印托着青浦新城。
