The new 304-m long, 12-m wide footbridge elegantly spans the Seine between the Bibliothèque Nationale and the Parc de Bercy, providing a variety of entry points at different heights on both sides. It is divided into two interpenetrating levels, providing a covered space at the middle for public use. The central, free-spanning, 194-m long main section combines suspension and compression systems. It is formed by two slender parallel arches, designed as box girders, balanced underneath by two parallel catenaries of 10 and 15 cm steel plate. At both ends of the bridge is an independently-supported 35 m-long arch girder spanning the freeway along the river.
