“Tercer Milenio” Bridge is an arch bridge crossing the River Ebro in Zaragoza. It was built for the International Exposition held in 2008. It is a tied-arch bridge with ties on the deck which rests on four vertical supports with a longitudinal distance between them of 216 m and a transversal distance of 48 m (including roadways, bicycle lanes and footpaths). The arch and inclined feet are in 75 MPa concrete with characteristic strength of white cement. The deck, also white, has a strength of 60 MPa. Another key feature area are the glazed pedestrian galleries, which protect pedestrians from the city's extreme climate, and give the bridge a unique personality. It was made in collaboration with engineer Juan José Arenas.
