日前由國際建築團隊 Zaha Hadid Architects、德國Leonhardt, Andrä & Partner及台灣中興工程顧問公司所贏得的淡江大橋（new Danjiang Bridge）國際競圖評選優勝可說是創造了不少話題，這座位於淡水河口的新淡江大橋同時也是北台灣基礎建設昇級計劃的項目之一。

預計落成後的新淡江大橋不但可加強淡水河二岸城鎮的互動，亦可減少國道2號、15號、西岸快速道路（61號）及八里-新店快速道路（64號）交通線互連下當地城鎮交通的負荷量，以及降低鄰近關渡大橋的交通量；同時，新淡江大橋也可用於改善北海岸的交通系統及加強台北港的運輸量，以及幫助淡海輕軌系統的延伸以連接八里地區與台北的公共運輸系統，新淡江大橋則預計於2020年底完工通車。

淡水河口二岸的自然生態環境一直是當地居民與遊客最喜愛休閒與欣賞日落美景的地區，因此在設計上設計團隊試圖只以單一混凝土基座配合纜索的方式來支撐長達920公尺的橋樑並減少對當地日落景色的影響，橋上並包含了軌道與鋼製成的行人甲板，而落成後的新淡江大橋同時也是全球最長的單塔不對稱的斜張橋。

設計團隊表示高175公尺的塔狀基座外形儘量朝纖細化設計，位置的擺設也以能符合最佳結構表現為主，同時也需考量到河川的適航性以及降低從河岸兩旁的熱門點觀賞日落時的影響；而單塔的設計也能減少河床上的結構元件以降低對河岸生態的衝擊。

Zaha Hadid Architects, working with Leonhardt, Andrä & Partner and Sinotech Engineering Consultants, have won the international competition to design the new Danjiang Bridge in Taipei for the Directorate General of Highways, Taiwan, R.O.C.
Located at the mouth of Tamsui River that flows through the capital Taipei, the Danjiang Bridge is integral to the infrastructure upgrading program of northern Taiwan. The bridge will increase connectivity between neighbourhoods and reduce through-traffic on local roads within local town centres by linking the Highways 2 and 15, with the West Coast Expressway (Route 61) and Bali-Xindian Expressway (Route 64). By also reducing traffic from the congested Guandu Bridge upriver, the Danjiang Bridge will greatly improve the northern coast traffic system and enhance accessibility throughout the region with the rapidly expanding Port of Taipei/Taipei Harbour, the region’s busiest shipping port.
The Danjiang Bridge will also allow for the extension of Danhai Light Rail Transportation (DHLRT) system over the Tamsui River to connect the town of Bali and the Port/Harbour with Taipei’s public rail network.
The Tamsui River estuary is a natural environment 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 cable-stayed bridge design minimises its visual impact by using only one concrete structural mast to support the 920m road, rail and pedestrian deck made from steel. The Danjiang Bridge will be the world’s longest single-tower, asymmetric cable-stayed bridge.
The mast is designed and engineered to be as slender as possible and positioned to offer the best structural performance, avoid impeding the navigability of the river and also minimise any interference with the views of the sunset from popular viewing points along the river. This single-mast design also minimizes structural elements in the riverbed in accordance with the increased protection programs of the estuary’s ecosystems.
Zaha Hadid Architects with Leonhardt, Andrä & Partner and Sinotech Engineering Consultants placed first in the competition. CECI and Nippon Engineering Consultants placed second; Aecom Asia and Resources Engineering Services placed third, MAA Group and Cowi placed fourth, with Oriental Consultants with Pacific Engineers & Constructors and Pyunghwa Engineering Consultants and Pacific Consultants with Taiwan Engineering Consultants and Yuang Engineering Consultants placing joint fifth.
Project Data:
Total Length: 920m
Height of Supporting Mast: 175 m
Structure: Concrete supporting mast with steel road/rail/pedestrian deck
Spans: 450m (to the West of the supporting mast)
175m (to the East of the supporting mast)
