Built over the River Ebro by Zaha Hadid and Ove Arup, the bridge combines three functions: Expo entrance, pedestrian footbridge and exhibition pavilion. It was designed by the Iraqi architect Zaha Hadid, the first woman to win the Pritzker Architecture Prize, with support from Ove Arup. Her project was chosen from among 41 design competition entries.
The bridge is built in a diagonal over the River Ebro, in the vicinity of the Third Millennium Bridge carrying the Rabal Ring Road. It has a gently curving line and connects the Delicias Intermodal Station with the Convention Centre on the Expo site, passing over a small island.
