The Gdora Bridge | BO Architecture Landscape Architects with Ofri Gerber

橋樑是一種促進兩地交通的工程結構，但它也可以提供情感體驗，兩點之間的移動有時可以帶來興奮感和寬廣的良好感覺。從高處往下看會加劇這種效果，並且在很大程度上增添了一種冥想的氛圍。
A 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.
在最開始對於如何在車流之上設計一座橋樑的頭腦風暴中，建築師尋求一種方式來反映這些感覺，並與過去和現在的語言環境保持聯繫。
As 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橋橫跨220米，供行人和自行車穿過位於Kiryat Bialik東南入口的Ha’amakim大道並前往Kiryat Ata。這座橋與Gdora河平行，沿著整條河流和城市的東部邊界將未來親水步道的兩頭連接起來。橋樑在本質上是通往Kiryat Bialik市的門戶和通道。
The 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.
作為Ha'amakim改造工程的一部分，BO建築事務所被委託為行人和騎行者設計一座橋樑，在Matronit電車穿過中心的情況下將街道擴展為四個車道，並將河道長廊的兩側連接起來。Gdora河流入城市周圍的田野並向南匯入Kishon河，它在Ha’amakim大道下方的地下通道中流淌，並在此出現在街道兩旁的明渠中。各種各樣的動植物、水生植物、鳥類、無脊椎動物和典型的水渠植被沿著河堤繁茂生長。
As 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.
設計區域的特點是沿河兩岸和街道兩邊都有大片的桉樹。
The zone designated for design, is characterized by large eucalyptus trees along the banks of the stream and on both sides of the street.
建築師的規劃挑戰是針對三個主要人群進行設計，即慢速行走的行人、快速通過橋樑的騎行者，以及Ha’amakim大道上的行人和司機，他們以不同的速度從下方體驗橋樑。
Gdora河和曾代表該地區的沼澤地作為當地古今的部分記憶，形成了多個層面上設計橋樑的靈感，即形式、地方感和運動體驗。
Our 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.
The 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 of movement.
形式
Gdora地區的歷史水流軸線受到土壤類型和水量的影響。在水被引到水道之前，它的彎曲路線成為橋樑設計的基礎。以類似的方式，建築師希望保留古老的桉樹並根據其現場位置來扭曲橋樑形態。
Form
The 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.
地方感
描繪出溪流特徵的蘆葦和水生綠植，隨風飄搖的植物，都為橋樑提供了靈感來源，垂直元素，包括兩排不同角度、不同高度的斜杆，每根斜杆都內置了彎曲的電路。欄杆由兩個表面組成，外表面由錫製成，其圓形孔具有典型的河床植被圖案，而內表面則由垂直元素製成的扶手組成。
當橋樑被照亮時，這兩個平面就形成了一種類似於蘆葦叢的霧狀效果。
Feeling of place
The 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.
When the bridge is illuminated, the two planes provide a haze effect, similar to that of a thicket of reeds.
光源被放置在安全屏障中，將周圍點亮，為橋上的行人和騎行者創造了一條光之隧道，而對從橋下穿行而過的司機來說，它們看上去就像是一片蘆葦叢。每根“蘆葦”的邊緣都有一道模仿夜空中螢火蟲的光。
運動體驗
從橋上和橋下經過是兩種不同的體驗，但移步換景之間，均能有所發現。人們在橋上所獲得的視覺體驗將隨著白天過渡到夜晚而發生改變。
The 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.
Experience of movement
Passing 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.
這座橋的曲線創造了一種有趣的步行體驗。在白天，人們可以清楚地看到桉樹和水；而在夜裡，橋樑則是一條光之管道，其牆壁通過扶手和高低不一的柱子頂部的燈光而得以強調。
The 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.
Ha’amakim大道上的司機和行人從遠處看到這座橋時，會將其看作是一條懸掛在斜杆上的金屬蛇，而靠近細瞧便會發現構成扶手的杆網。到了晚上，這座橋遠遠望去便像一排螢火蟲縈繞般的柔光。當人們靠近時，他們將能感受到從外面分辨出由錫飾板和桿狀結構所形成的朦朧的光線。
不同的文化將跨越橋樑成為設計理念。在這個項目中，建築師試圖將另一個維度的驚奇、觀察和情緒提升引入進來。
Drivers 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.
