位于瑞士阿劳的新阿勒河大桥由Christ & Gantenbein、WMM Ingenieure AG、Henauer Gugler AG和August + Margrith Künzel Landschaftsarchitekten AG等规划团队设计，既是现代基础设施，也是城市的一部分。新结构取代了1949年的混凝土桥，有机地融入了阿劳独特的城市景观和阿勒河的自然环境，同时强化了该地区的交通网络。作为一个综合性的桥梁及河畔设计，该项目创造了一个吸引人的城市空间，并以其独特的，优雅的弧形拱门，成为新地标。
The new Aare Bridge in Aarau, Switzerland, designed by the planning team Christ & Gantenbein, WMM Ingenieure AG, Henauer Gugler AG, and August + Margrith Künzel Landschaftsarchitekten AG, is both a modern infrastructure construction and a part of the city. Replacing a 1949 concrete bridge, the new structure blends organically into Aarau’s distinctive cityscape and the natural environment of the Aare river while strengthening the region’s transportation network. As a comprehensive bridge and riverbank design, the project creates an appealing urban space, and with its distinctive, elegantly curved arches, becomes a new landmark.

自罗马时代以来，就有一座桥在这里横跨阿勒河，从历史悠久的市中心Zollrain区域，向北通往汝拉。这座桥已经被更新替换数次，包括1848年的“Ketten- brücke”和1949年的一座混凝土桥。因此，寻求替代老旧桥梁的这次竞赛强调新桥应适应城市环境。此次获奖的设计因其与城市结构的联系以及在历史老城区入口处创造一个引人入胜的公共空间，在众多方案中脱颖而出。如今，这座桥无缝地过渡到湖畔护墙上，与河流和谐地融为一体。
Since Roman times, there has been a bridge over the Aare at this location – from the historical city center over the Zollrain towards the north, to the Jura. This bridge has been replaced several times by new structures, including the 1848 “Ketten- brücke” and a concrete bridge from 1949. As such, the competition which sought a replacement for the aging predecessor emphasized that the new bridge should fit into its urban context. The winning design distinguished itself through this very connection to the urban structure and the creation of an inviting public space at the entrance to the historical old town. Today, the bridge seamlessly transitions into the riverbank walls, harmoniously connecting it with the river.

这座新桥既是传统结构，也是技术优化的混凝土结构。灵感启发自阿劳坚固的石头房屋、沿城墙的中世纪房屋、附近的桥墩，挡土墙、坡道和河岸加固工程，新桥的浅色调延续了结构与周围环境的对话。同样，这座桥是一个理性的、现代的拱形钢筋混凝土结构，得益于其特殊的几何形状，只使用了少量混凝土。拱桥的五跨分别有着不同的跨度，部分桥体坐落在旧桥埋于河床的两个基础沉箱上，将其重新利用。桥梁施工的另一个重要方面是其整体支撑结构，其中所有部件——柱基，支柱，桥拱，侧翼，步行道，护墙——构建了一个统一的无缝的结构。所有元素都参与承重，从而形成优化的可持续结构。

The new bridge is both a traditional structure and a technically optimized, concrete construction. Inspired by the solidity of the stone buildings in Aarau, the medieval houses along the city wall, the nearby piers, retaining walls, ramps, and riverbank reinforcements, its light coloring maintains the dialogue of the structure with its surroundings. Equally, the bridge is a rational, modern archlike reinforced concrete construction, which employs concrete sparingly thanks to its specific geometry. The five spanning arches of different widths partially rest on the two caissons of the old bridge located in the riverbed, thus enabling their reuse. Another important aspect of the bridge construction is its monolithic supporting structure, in which all of the components – pillar foundations, pillars, arches, flanks, roadway, parapets – build a uniform, seamless construction. All elements participate in load-bearing, leading to an optimized and thus sustainable structure.

这座桥长119米，宽17.5米，有两条车道，两边为人行道和自行车道。在护堤小路穿过桥梁的地方，桥梁底部的巨大开口提供了横贯周围环境的视野，从而为每个沿阿勒河散步、慢跑或骑自行车的人创造了极具吸引力的公共空间。新的河岸将桥梁与城市连接起来，现有的步行道被加强并被重新诠释：在老城区一侧，一个宽敞的带有广场的城市步行街正在建设，供人们在树荫下悠闲休憩。在北岸，大桥被绿色草地和本地地植被所妆点。
With a length of 119 meters and a width of 17.5 meters, the bridge features two lanes, sidewalks on both sides, and bicycle tracks. Where the riverbank path spans the bridge, large openings offer transverse views of the environs, thus creating attractive public spaces for everyone walking, jogging, or cycling along the Aare river. The new riverside links the bridge to the city where existing promenades are enhanced and newly interpreted: on the old town side, a spacious urban promenade with a square for lounging beneath shady trees is being created. On the northern riverbank area, the bridge is embellished with green meadows and local vegetation.

乍一看，新阿勒河大桥是一座传统的桥梁，但仔细审视，它是一个技术优化的工程结构。它的建筑设计敏锐地为城市环境的发展做出了另一层次的贡献，使城市对居民更具吸引力。
At first glance, the new Aare Bridge is a traditional bridge, but upon closer inspec- tion, it is a technically optimized engineering structure. Its architectural design dis- cerningly contributes another layer to the evolution of our urban environment, making the city more attractive to its inhabitants.
