此方案的目的在于給行人提供一座新的橫跨歐韋爾河的步行橋，以連通A6高速路和河北岸的草甸。橋的建造將有助于激活連接索爾福德及曼徹斯特的主要通道的巨大發展潛力。平面呈Y字形，由三個折疊平臺組成，其中一個平臺作為橋主體，其余兩個是向河面延展的坡道和平臺，它們包裹成景觀雕塑，并且引導行人走向已有的沿河人行道。 整個結構呈折疊狀，用來抵消歐韋爾河岸兩側4米的高差。平臺的疊放使橋體與草甸河岸產生輕柔的接觸。我們把這個方案看成草甸區未來發展的首要元素。 它將成為一個多功能的元素，一個宜于沉思與娛樂的場所，一個漫步長廊和一個地標。這座橋應該成為一個焦點，它可以承載體育和文化活動，促進人與人之間的溝通交流，成為一個名副其實的游樂場所。 結構是由一個57米跨度單支柱支撐的鋼箱梁構成。橋梁被錨固在混凝土墩子上，被反向固定。鋼箱梁結構提供了幾何上的自由度并為后期保養提供便捷。動態效果通過折疊被縮減。

the scope of this project is to provide a new crossing for pedestrians, over the river irwell from the A6, to the Meadow on the north of the river. it will help to unlock the vast development potential of a major corridor linking salford and Manchester. the plan is a symmetrical Y, composed of three folded platforms, one being the Bridge. the other two platforms are ramps and terraces that extend along the river, wrap the landscape sculpture and lead people to the existing boardwalk. the entire structure is folding such as to absorb the four meters of difference in level between the two sides of the irwell river. the superposed platforms allow a soft landing on the shore of Meadows. We see the project as a fi rst element of a future development of The Meadows. It will become a versatile element, a space for contemplation and entertainment, a promenade and a landmark. the Bridge should be an attraction; it can host sports and cultural events. it can encourage exchanges and communication between people and become a true playground. the structural scheme is a steel Box Girder supported by a single pillar, over a span of 57m. the Bridge beam will be anchored to the concrete pillar, and blocked on the opposite side. steel Box Girder construction allows considerable freedom in the geometry of the Bridge and an easy maintenance. the dynamic effects will be reduced by folding the deck.
