Choisy-le-Roi新桥穿越RERC郊区铁路客运服务区和巴黎南部地区。这座大桥共有70米长，并且每一个方向上都有行车道。由于它位于铁路线和塞纳河之间，所以不得不将这座大桥切断，并进行重新设计。新的大桥恢复了与港口地区的连接，包括房屋，基础设施，办公室，国家研讨会，Anatole France大街和镇中心大道。这座大桥是保证该地区经济繁荣发展的一个重要因素。

设计首要考虑的就是，本地区需要有不间断的交通流，夜间可以有两个小时的消息时间，该项目的技术和构架设计必须满足交通需求。要想满足这些条件，新的大桥只能设计成双梁直线模式，这样的解决方案，同时也确保了整个跨度中不需要任何中间支持。

The new Choisy-le-Roi bridge crosses the RER C suburban express railway lines serving passenger traffic to and from the southern Paris region. The 70 m long bridge has a traffic lane in each direction contained within wide footpaths to either side. Connecting the recently rehabilitated Port district with its housing, amenities, offices and Imprimerie Nationale workshops as well as Avenue Anatole France to the town centre, the bridge is an essential element in guaranteeing the success of this new district which, until now, has been cut off from the city due to its location between the railway lines and the River Seine.

The need for uninterrupted traffic flow – with the exception of a two hour break at night – represented the point of departure for the project’s technical and architectural design. It resulted in the bridge being designed as a straight double beam preassembled on one side of the railway lines which was then pushed out over the tracks in two operations, a solution that ensured that the overall span did not require any intermediate supports.
