High-Speed Railway Bridge over the Ebro River, Spain

The bridge over the Ebro River is located on the High Speed Railway Line Madrid-Zaragoza-French border. The bridge has an innovative deck in which the Designer tried to adapt the concept of the metallic lattice of large railway bridges to the structural and construction domain of prestressed concrete bridges. The cross section is made of a box girder whose webs contain circular voids and connected by ribs in the upper part. From the structural point of view, this is actually a Vierendeel girder. Its total length amounts to 546 m with the following span distribution: 18 m + 6 m x 24 m + 60 m + 120 m + 2 m x 60 m + 42 m.
