The Gdora Bridge | BO Architecture Landscape Architects with Ofri Gerber |
bridge is an engineered structure whose purpose is to facilitate passage from
one location to another, but it can also provide an emotional experience: the
movement between two points can sometimes provide a sensation of excitement and
expansive good feelings. Looking down from a great height intensifies the
sensation, and, for the most part, adds a meditative dimension.
part of our initial brainstorming about designing the bridge over the Gdora
stream, we sought a way to reflect these sensations along with maintaining a
bond to the past and present values imbued in the locale.
Gdora Bridge spans 220 meters, for pedestrians and cyclists to pass over
Ha’amakim Street at the southeastern entrance to Kiryat Bialik heading towards
Kiryat Ata. The bridge runs parallel to the Gdora stream, connecting the two
parts of a future promenade that will pass alongside the entire length of the
stream and the city’s eastern border. The bridge essentially serves as the
gateway to the city of Kiryat Bialik as well as acting as a passageway.
part of the Ha’amakim renewal project, expanding the street into four lanes
with the Matronit tram running through the center, BO Architecture was
commissioned to design a bridge for pedestrians and cyclists, that would
connect the two sides of the streams’ promenade. The Gdora (Fuara) stream,
which drains the fields surrounding the city and flows southward into the
Kishon, flows in an underground channel underneath Ha’amakim street, and
surfaces again to an open channel on either side of the street, where a wide
variety of flora and fauna, water plants, birds, invertebrates and vegetation
typical of waterways lives along the banks.
zone designated for design, is characterized by large eucalyptus trees along
the banks of the stream and on both sides of the street.
planning challenge was to design for three major target audiences: pedestrians
who may be walking slowly, cyclists passing rapidly over the bridge, and
drivers and those on foot passing through Ha’amakim Street at varying speeds
who experience the bridge from below.
Gdora stream and the swampland that characterized the area in the past are part
of its history and present memory of place, forming our inspiration for
designing the bridge on several levels: form, feeling of place, and experience
historical axes of flow of the Gdora area were impacted by the type of soil and
amount of water. The winding route of the water before it was diverted into the
channel became the foundation for the design of the bridge. In a similar
manner, we wanted to preserve the old eucalyptus trees, which lead to the need
to twist the bridge in accordance with their location on site.
thicket of reeds and water plants that characterize the stream, along with the
movement of the plants in the wind served as the source of inspiration for all
of the bridge’s elements: the vertical elements; comprising of two rows of
diagonal poles, each in a different angle and different height, within which
the curving contour is placed. The railing is made of two surfaces: the
external plates are made of tin, with circular holes exhibiting patterns of
vegetation typical of streambeds, while the internal surfaces comprise of
handrailing made of vertical elements.
the bridge is illuminated, the two planes provide a haze effect, similar to
that of a thicket of reeds.
light source is placed in the safety barrier, illuminating its sides, creating a
tunnel of light for pedestrians and cyclists on the bridge and looking like a
reed thicket to the drivers passing underneath the bridge. At the edge of each
vertical element is a light that imitates that of fireflies in the night sky.
over the bridge provides a different experience to that of passing under the
bridge, but what they share is the discovery of transition from seeing the
bridge from a distance and seeing it up close. The visual experience one gains
from the bridge changes as day transitions into night.
twisting curves of the bridge create an interesting walking experience. During
the day, the eucalyptus trees and the water are seen clearly; whilst the
nighttime bridge is a pipeline of light whose walls are emphasized by handrails
and lighting at the top of the poles of varying heights dotting the route.
and pedestrians on Ha’amakim Street, spotting the bridge from a distance, will
see it as a metallic snake hanging on diagonal poles. A closer look reveals the
network of rods making up the handrail. At night, the bridge stands out from
afar like a line of light with firefly-like illumination above it. As people
draw near, they will be able to distinguish the light in the haze formed by the
tin plaques with the pattern of rods enveloping the bridge from the outside.
Different cultures view bridges as a parable of life which one must cross. In this project, we are attempting to add another dimension of amazement, observation, discovery and a sensation of mood elevation.
