Third Millennium Bridge

Zaragoza, Spain


The Third Millennium Bridge is the largest concrete tied-arch bridge in the world, with an arch span of 710 feet; its typology is bow-string with concrete bow and deck. The deck is 140 feet wide and is formed by two lateral box girders connected by transverse beams and the slab.

The bridge was constructed using the incremental launching method. The deck is suspended by the bow, which has a markedly three-dimensional character because in each one of its ends, it is split into two to support the deck.
