Airport Station connects Lyon and the Saint-Exupéry Airport, in Satolas.
The competition brief called for a building that would provide smooth
passenger flow while creating an exciting and symbolic ³gateway to the
triangular Central Hall, spanning 120 meters, sweeps upward toward a
service concourse on the east side, that accommodates ticket offices, retail
shops, restaurant facilities, a temporary exhibition space, and access to
the airport. This multilevel service block leaves the Central Hall free of
visual obstructions. The service concourse is connected to the airport by a
raised, 180-meter steel gallery,which in turn connects to a covered
extension for pedestrian access to the parking garage, underground service
area and elevators.
form of the Central Hall, resembling a bird at the point of flight, derives
from one of Calatrava¹s sculptures. The steel roof is composed of four
converging arches with a curved, tapering, arched spine.
arches, which support the central spine, spring from a lintel placed across
the elevator towers, the outer arches spring from two tapering concrete
buttresses on each side of, and beyond, the eastern facade. A single,
sculpted, V-shaped, concrete footing supports the arches at their point of
convergence on the west.
screens fill the area between the central, concrete arches of the Platform
Hall and the two outer steel spans of the concourse roof, stabilizing the
structure. The arches to either side of the central concourse also form the
portals to the platforms. Floodlights are recessed into the upper, exterior
surfaces of the portal arches, providing reflected illumination onto the
Hall, on the project¹s lower level, spans a central enclosed caisson, which
shields waiting passengers from the non-stop, high-speed trains (300 km/h)
that run on two central tracks.
caisson¹s cover forms the walkway of the platform hall, a 500 meter long,
arched concrete structure, bridged at two points by a unifying, symmetrical
road pattern. Access to the platforms is provided via concrete bridges,
stairs, escalators and glass elevators.
vault of intersecting diagonal arches spans the platforms to create a
lamella roof spanning 53 meters. The structure was cast in situ, including
recesses for light fittings. Through the use a local white sand in the mix,
the concrete has a natural color. Above the tracks, the matrix of this roof
is open to the sky; above the platforms, it is either glazed or filled with
prefabricated concrete slabs.
serve the station, two on each side of the central walkway, and provision
has been made for two further tracks outside the platform hall to serve
³Satorail,² the future regional connection to Lyon.
