Zorrotzaurre Bridge

Bilbao, Spain
43.267586, -2.954752

The future Zorrotzaurre Island in Bilbao (currently a peninsula) will be connected with the rest of the urban fabric by a series of bridges. This first one will clear the watercourse of the Deusto Canal, when completed, with a main span of 76.9 m and an average width of 28 m. Its innovative design concept combines two structural schemes: an inverted Fink truss (it will be the first road bridge in the world of this type to be built) and a three- span variable-height beam. This design (made of steel with a composite road deck) provides transparency and slenderness, fulfils the hydraulic requirements, has an accurate scale for an urban bridge (the height of the main mast is 15.4 m) and serves as a tribute to the sequence of cranes and towers that were plentiful in the once industrial area.
