全球最長單塔不對稱斜張橋 「淡江大橋」主橋段開工

發布時間 : 2019.03.21

橫跨淡水河出海口,淡江大橋(Danjiang Bridge)是北台灣基礎建設升級計劃的項目之一,同時也是全球最長的單塔不對稱的斜張橋。

預計落成後的淡江大橋,不但可加強淡水河二岸的城鎮互動,亦可舒緩國道2號、台15線、西部濱海快速道路(台61線)及八里-新店快速道路(台64線)相關城鎮的交通負荷,降低上游五公里處關渡大橋30%的交通量;同時,淡江大橋也可改善北部海岸的交通網絡,並強化台北港及北部機場的運輸量;延伸淡海輕軌系統以連接淡水河左岸與台北的公共運輸網絡。由國際建築團隊 Zaha Hadid Architects(ZHA)、Leonhardt, Andrä & Partner德國理安公司及Sinotech台灣中興工程顧問公司於2015獲得此項目的競圖優勝。

歷經7次流標,淡江大橋於2019年3月14日舉行第三標動土典禮。總統蔡英文稱淡江大橋將為八里與淡水之間的交通時間節省25分鐘。預算為新台幣124.9億元的淡江大橋預估以68個月的施工時間,在2024年完工通車。

淡水河口身為台灣北部重要的自然生態區域,兩岸分別為是淡水和八里的市鎮中心,一直是當地居民與遊客欣賞台灣海峽日落的休閒景區。除了專用道路、自行車道和行人專用道,淡江大橋的設計規劃同時符合淡海輕軌的未來擴建。

淡江大橋以單一混凝土基座配合纜索的方式來支撐長達450公尺的主橋段,設計團隊讓200公尺高的橋塔盡量朝纖細化設計,以減少河口自然風景的視覺衝擊。橋塔的位置同時兼具最佳的結構性能、河川的適航性且不影響熱門夕陽觀景點的視線;並以單一橋塔的設計,減少了河床上結構元件的入侵,降低對河岸生態的衝擊。

Spanning the mouth of the Tamsui River that flows through Taipei, the Danjiang Bridge is integral to the infrastructure upgrading program of northern Taiwan.

The new bridge will reduce through-traffic on congested local roads by linking Highway 2 on the river’s eastern side with Highway 15, the West Coast Expressway (Route 61) and the Bali-Xindian Expressway (Route 64) on the western side.

In reducing traffic by 30% on the existing Guandu Bridge 5km upriver, the Danjiang Bridge will significantly improve Taiwan’s northern coast traffic network and also enhance accessibility throughout the region with the Port of Taipei and Taoyuan International Airport.

The Tamsui River estuary is an important natural ecosystem flanked by the urban centres of Tamsui to the East and Bali to the west. The estuary is rapidly growing in popularity with both residents and tourists as a recreational area where people gather each day to watch the sun setting over the Taiwan Strait.

The bridge minimizes its visual impact by using a single concrete mast to support its main 450-metre span with the dedicated road, cycle and pedestrian lanes. The design also accommodates future expansion of the Danhai Light Rail network across the Tamsui River. 

Sinotech Engineering Consultants and Leonhardt, Andrä and Partner joint venture with Zaha Hadid Architects, the bridge’s 200-metre mast is engineered to be as slender as possible.

Project: Danjiang Bridge
Location: Taipei, Taiwan
Date: 2015/2024
Client: Directorate General of Highways,M.O.T.C.
Status: Under Construction
Length: 920m (total)、450 (longest span)
