Photographer Luke Hayes has sent us these photos of Zaragoza Bridge Pavilion, a pavilion by Zaha Hadid Architects at Zaragoza Expo 2008 that doubles as a pedestrian bridge across the river Ebro in Zaragoza, Spain.
The pavilion, and the expo itself, opened this weekend.
Zaragoza Expo 2008 is dedicated to water and sustainable development.
Here's some info from Zaha Hadid Architects:

ZARAGOZA BRIDGE PAVILION [ZARAGOZA, SPAIN]
The Zaragoza Bridge Pavilion is organized around 4 main objects, or
「pods」 that perform both as structural elements and as spatial
enclosures. The Bridge Pavilion design stems from the detailed
examination and research into the potential of a diamond shaped section
- which offers both structural and programming properties. As in the
case of space-frame structures, a diamond section represents a rational
way if distributing forces along a surface.
Underneath the floor plate, a resulting triangular pocket space can be
used to run utilities. Floors inside each pod are located at the Expo
principal levels: +201.5m (the soffit of the bridge is at +200m, flood
protection minimum level of the Ebro River at the location of the
Bridge Pavilion) +203m, +206m and +207.5m for the upper level.
The diamond section has also been extruded along a slightly curved
path. The extrusion of this rhombus section along different paths has
generated the four separate 『pods' of the Bridge Pavilion. The stacking
and interlocking of these truss elements (the 『pods'), satisfies two
specific criteria: optimizing the structural system, and allowing for a
natural differentiation of the interiors, where each pod corresponds to
a specific exhibition space.
By intersecting the trusses/pods, they brace each other and loads are
distributed across the four trusses instead of a singular main element,
resulting in a reduction in size of load-bearing members.
The pods are stacked according to precise criteria - aimed at reducing
the section of the bridge as much as possible where the span is longer
(approximately 185m from the island in the middle of the river to the
right bank), and enlarging it where the span is shorter (85m from the
island to the Expo riverbank). One long pod spans from the right
riverbank to the island, where the other three are grafted into it,
spanning from island to left bank.
This interlocking of the pods has given the design many exciting
possibilities. Interiors become complex spaces, where visitors move
from pod to pod though small in-between spaces that act as filters - or
buffer zones. These zones diffuse the sound and visual experience from
one exhibition space to the next, allowing for a clearer understanding
of the installation content within each pod. The identity of each pod
remains thoroughly readable inside the pavilion, almost performing as a
three-dimensional orientation device.
Spatial concern is one of the main drivers of this project. Each zone
within the building has its own spatial identity; their nature varies
from complete interior spaces focused on the exhibition, to open spaces
with strong visual connections to the Ebro river and the Expo.
Natural surfaces have been investigated when designing the Pavilion's
exterior surfaces. Shark scales are fascinating paradigms both for
their visual appearance and for their performance. Their pattern can
easily wrap around complex curvatures with a simple system of
rectilinear ridges. For the Bridge Pavilion, this proves to be
functional, visually appealing and economically convenient.
The building's envelope plays an essential role in defining its
relation to the surrounding environment and atmospheric variations. The
project has been designed to allow its interior to be thoroughly
enlivened by the effect of atmospheric agents, such as the Tramontana
wind blowing along the Ebro and, the strength of Zaragoza's sunshine.
During the Expo, a single weathering layer will enclose the building to
protect it from rain. This Shark scale skin will be generated by a
complex pattern of simple overlapping
shingles. Some shingles can rotate around a pivot, allowing for
temporary opening or closing of part of the façade. The pattern of
shingles overlapping each other gives the Bridge Pavilion the widest
variety of natural light via several degrees of aperture sizes: from
rays piercing through tiny apertures - to wide, full size openings.
Large apertures are located on the lower level, in correspondence with
either end of the bridge, allowing for the greatest degree of visual
contact with the river and the Expo.
