OMA建筑事务所为波尔多设计了一座跨越加伦河的新大桥，方案最终被成为入围的两个方案之一。他们精简的设计试图重新思考公共设施的功能和21世纪桥梁的象征意义。Clement Blanchet与雷姆?库哈斯领导了这次设计，他认为，“桥梁本身不是城市内的重要事件，但是它有可能成为一个承载重要事件的平台。我们希望提供一种最简单原始的建筑表达方式，尽量少地采用技术、抒情。这样才能为市民和公共活动提供最开放的平台；在未来容纳各种交通方式上，也会有极大的灵活性。” 波尔多城市社区领导人Vincent Feltesse与评审委员会的40人作出决定，希望设计里有一些“大胆”的元素。所以除了传统风格和技术手段，OMA试图利用现代技术，创造出一条属于现代的大道。大桥宽44米，545米长，高出水面，与两岸土地无缝连接。这座桥十分平滑，提供了轻松的散步长廊，河上的游船也能在此停留。汽车、电车和公交车、自行车都有各自的车道；车道还能根据需要变动。而其中最宽的道路则是为行人设计的。这座桥为了与邻近的St. John Belcier城市重建项目相配合，在河两岸有不同的处理手法。右岸严格与草地牧场对齐，延伸到左岸的城市景观，目的是解决这里严峻环境问题对现状和未来的双重挑战。评审委员会将在今年12月在OMA与Dietmar Feichtinger的这两个入围方案中做出选择，预计项目在2018年建成。

OMA's design for a new bridge across the river Garonne in Bordeaux has been selected as one of two final competing projects by the city authorities. OMA's stripped-down design for the Pont Jean-Jacques Bosc attempts to rethink the civic function and symbolism of a 21st century bridge. Clement Blanchet， leading the project for OMA with Rem Koolhaas said: "The bridge itself is not the 'event' in the city， but a platform that can accommodate all the events of the city. We wanted to provide the simplest expression – the least technical， least lyrical， an almost primitive structural solution. This simplicity allowed us to create a generous platform for pedestrians and public programs， as well as flexibility in accommodating the future needs of various types of traffic." Vincent Feltesse， president of Urban Community of Bordeaux made the decision with the deliberation of a jury of 40 people， announcing that the municipality wanted something "bold." Beyond traditional fascinations with style and technical performance， OMA tried to design a 21st century bridge that exploits state-of-the-art techniques in order to create a contemporary boulevard. A platform 44 metres wide and 545 metres long is stretched beyond the water on either side， creating a seamless connection with the land. The bridge slopes gently， allowing an easy promenade while still giving necessary clearance for boats underneath. Each type of traffic – cars， RBD (tram/bus)， bicycles – has its own lane， and is designed to meet changing vehicular needs. By far the largest strip is devoted to pedestrians. The bridge is designed to cohere with the adjacent St. John Belcier urban redevelopment project. It also attempts to unify the different conditions of the two banks of the Garonne: from the Right Bank， strictly aligned on a poplar-lined meadow， to the urban landscape of the Left Bank， it aims solve the dual challenge of aura and performance in an environment steeped in history. A final decision between designs by OMA and Dietmar Feichtinger will be made in December this year， with the bridge scheduled for completion in 2018. The project is developed in collaboration with engineers WSP， the landscape architect Michel Desvigne， as well as the consultant EGIS and light design agency Lumières Studio.
