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(fā)展?jié)摿?。平面呈Y字形，由三個(gè)折疊平臺(tái)組成，其中一個(gè)平臺(tái)作為橋主體，其余兩個(gè)是向河面延展的坡道和平臺(tái)，它們包裹成景觀雕塑，并且引導(dǎo)行人走向已有的沿河人行道。 整個(gè)結(jié)構(gòu)呈折疊狀，用來(lái)抵消歐韋爾河岸兩側(cè)4米的高差。平臺(tái)的疊放使橋體與草甸河岸產(chǎn)生輕柔的接觸。我們把這個(gè)方案看成草甸區(qū)未來(lái)發(fā)展的首要元素。 它將成為一個(gè)多功能的元素，一個(gè)宜于沉思與娛樂(lè)的場(chǎng)所，一個(gè)漫步長(zhǎng)廊和一個(gè)地標(biāo)。這座橋應(yīng)該成為一個(gè)焦點(diǎn)，它可以承載體育和文化活動(dòng)，促進(jìn)人與人之間的溝通交流，成為一個(gè)名副其實(shí)的游樂(lè)場(chǎng)所。 結(jié)構(gòu)是由一個(gè)57米跨度單支柱支撐的鋼箱梁構(gòu)成。橋梁被錨固在混凝土墩子上，被反向固定。鋼箱梁結(jié)構(gòu)提供了幾何上的自由度并為后期保養(yǎng)提供便捷。動(dòng)態(tài)效果通過(guò)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.
