finally the bridge pavilion opened last friday 13 june, along with the international expo2008 in zaragoza, spain. Here are some shots by photographer luke hayes via dezeen.
more progress construction photos of the bridge provided by Manuela Gatto, the lead architect. both parts of the bridge are about 24 m apart and will be pulled together in a few days.
latest site photos of the bridge, provided by the project architect manuela gatto.
photos were taken on the day before the right bank portion, seen below (138 meters long and weighing 2070 tons), was launched 27 meters over the river ebro connecting to the other half already in place.
here are a few more photos of the bridge on site, provided by Manuela Gatto.
bridge deck was created by a series of "diaphrams" or ribs with steel paneling underside, bent and welded at the central support "belly" to form double curvature. 2 spinal arches "top chords" transfer loads to the pilecaps at both ends and centre of the bridge. connecting the deck to the "top chords" is the faceted diagrid which also acts as the secondary facade structure.
it was a great project to work on, rationalizing the geometry from the competition stage to construction documents, achieving repetition in the facade panelization while using planar structural elements to reduce cost.
all modeling was done in Rhino 3. Shop drawings were generated from a Catia 3d model.
construction photos taken earlier this year by manuela gatto, project architect.

the bridge pavilion was commissioned as the 'iconic' entrance to the 2008 world expo in zaragoza, españa. 300m long with 2 levels, it is composed of 4 pods: 2 & 4 being the central , open-aired pedestrian passage flanked by pods 1 & 4 on both sides. the bridge will house a water conservation exhibition on the upper levels.
