Christ&Gantenbein Architects： 由 Christ & Gantenbein、WMM Ingenieure AG、Henauer Gugler AG 和 August + Margrith Künzel Landschaftsarchitekten AG 组成的规划团队，为瑞士阿劳（Aarau）地区设计了一座新的桥梁——阿勒河大桥，它既是一个现代基础设施结构，也是城市的一部分。新的桥梁结构取代了1949 年的混凝土桥，有机地融入了所在地区独特的城市景观和阿勒河的自然环境，同时加强了该地区的交通网络。作为一个综合性的桥梁和河岸设计，该项目创造了一个有吸引力的城市空间，并以其独特的、优雅的弧形桥拱，成为一个新的地标。
Christ&Gantenbein Architects: 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.
自罗马时代起，这里就有一座桥，从历史悠久的城市中心穿过佐拉河向北一直延伸到汝拉河。这座桥曾多次被新的结构所取代，包括1848年的“Kettenbrücke”和1949年的一座混凝土桥。因此，寻求替代老旧桥梁的竞赛方案应当强调新桥梁与城市环境的适应性。获胜的设计方案通过与城市结构的联系和在历史悠久的老城区入口创造一个吸引人的公共空间而脱颖而出。如今，这座桥完美地过渡到河岸墙壁上，与河流和谐地连接在一起。
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 “Kettenbrücke” 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.
这座新的大桥既是一个传统的结构，也是经过技术优化的混凝土结构。受Aarau石头建筑的坚固性、沿城墙的中世纪房屋、附近的桥墩、挡土墙、坡道和河岸加固物的启发，大桥的浅色调使其与周围环境的相协调。同时，这座桥也是一座理性的现代拱形钢筋混凝土结构，但由于其特殊的几何形状，结构中的混凝土使用量很少。
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.
五个不同宽度的桥拱部分位于河床中旧桥结构的两个沉箱上，从而使它们得以重新使用。大桥建设的另一个重要方面是它的整体支撑结构，其中所有的组成部分：支柱基础、支柱、桥拱、侧翼、路基、护栏，构建了一个完整统一的结构。所有的元素都参与了承重，从而形成了一个最优的可持续结构。
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.
大桥长119米，宽17.5米，有两条车道，两侧还有人行道以及自行车道。在河岸小路与大桥相汇的地方，桥身大的开口提供了周围环境的横向视野，从而为每个沿阿勒河散步、慢跑或骑自行车的人创造了有吸引力的公共空间。新的河岸将大桥与城市连接起来，现有的步行长廊在这里得到了完善和新的诠释：在老城区一侧，一个宽敞的城市步行街正在建设中，其中包括一个可以供人休息的树荫广场。在河岸北部地区，大桥被掩映在绿色的草地和当地的植被中。
乍一看，新的阿勒河大桥是一座传统的桥梁，但仔细观察会发现，它是一个技术上最优的工程结构。其结构设计独具慧眼，为城市环境的发展做出了另一层贡献，使城市对居民更具有吸引力。
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.
At first glance, the new Aare Bridge is a traditional bridge, but upon closer inspection, it is a technically optimized engineering structure. Its architectural design discerningly contributes another layer to the evolution of our urban environment, making the city more attractive to its inhabitants.
