项目背景
Background

元荡，地处沪苏边界，与淀山湖相接，因芦滩封淤而成为淀山湖的一个子湖。当地水网密布，村落众多。原两岸虽仅一衣带水，但来往不便。

如今，环元荡贯通桥（以下简称“元荡桥”）连通上海青浦与江苏吴江的两岸，加速长三角一体化示范区的发展进程，这也是该示范区的首座新建慢行桥。

The Yuandang Pedestrian Bridge celebrates the coming together of Jiangsu Province and Shanghai.

衔接风貌：糅合本土元素
Blending with local elements

元荡桥全长586米，整体设计以“同心结”为理念，体现青吴两地同心共治的发展愿景。

桥身如同一条缎带，连同揉入湖水柔波元素的桥上栏杆，与元荡湖上的水波交相呼应。景亭中的太湖石小品，灵感源自当地传统雕塑，设计上探索了当代数字建模及制作，创造了既是雕塑又是游乐场的多孔墙。

The 586m bridge is a hybrid structure incorporating landscape, infrastructure, and architecture. It is located in a key location where the two jurisdictions meet.

桥上桥下的绿化种植延续了两岸生态公园的原生态种植理念，结合对本土植物及动物的思考。将树木和灌木融入到桥中，构建了一座连接两岸的浮动花园。

The figure of the bridge resembles a ribbon and echoes water ripples on the Yuandang Lake below. Trees and shrubs are incorporated in the bridge, giving the appearance of a floating garden connecting the two banks.

这些融入本土环境的巧妙设计，使整座桥梁成为元荡湖上的一道别致景观。与此同时，元荡桥也串联了周边千帆归渡、闲梦云台、汾湖之眼等旅游资源，形成一段连续的生态之旅。

移步异景：特色线性安排
Cycling path, vegetation band and walking path

元荡桥的桥面标准段横断面布置为：2m（人行道）+2m（绿化带）+2m（自行车道）=6m，分为骑行、慢行、绿化三条线性，多种情境和氛围在桥面交织。

The six-meter-wide bridge deck is divided into three bands: cycling path, vegetation band and walking path. The winding bridge has three widened sections for resting and enjoying the lake view.

在行进的方向上，步行者和骑行者进入不同的线路，绿化带将两者间隔开来，这种线性设置为当地居民的健康生活划分安全边界。曲桥有三个加宽的部分，各条线路相合，并加入休闲长凳、观景平台、景观亭等，可供游人休憩及观赏湖景。

这种线路设计延续了江南文化的动观为游，妙在步移景异，奇在风景如画。游赏相间，动静交替则元荡湖之景致尽入眼中。

Taking inspiration from local sculptural traditions, the bridge’s pavilion explores contemporary mathematics modeling to create a porous wall that is both sculpture and playground.

结语
Epilogue

元荡桥是一个集生态、交通、景观、文化于一体的动态整体。桥梁的建设使吴江、青浦的生态景观保持连续性，形成和谐统一的蓝绿慢行体系，从而提升元荡湖区域的环境品质。它的建成既实现了两区蓝绿体系直接联通，也满足当地居民游览、休闲、观赏等需要。

The bridge is a dynamic ensemble, integrating ecology, transportation, landscape, and culture.
