多多羅大橋在日本廣島的俯視圖

The Tatara Bridge is a cable-stayed bridge that is part of the Nishiseto Expressway,
commonly known as the Shimanami Kaido . The bridge has a center span of 890 metres
(2,920 ft).As of 2010 it has the fourth longest main span of any cable-stayed bridge after
the Sutong Bridge. The expressway is a series of roads and bridges that is one of the three
routes of the Honsh?-Shikoku Bridge Project connecting the islands of Honsh? and Shikoku
across the Seto Inland Sea in Japan. The Kurushima-Kaikyo Bridge is on the same route.
日本多多羅大橋是一斜拉橋，它是西瀨戶高速公路，俗稱島波海道的一部分。這
座橋有890米（2920英尺）的中心跨度。該高速公路是一系列的道路和橋樑，它是
本州四國聯絡橋工程的三條路線橫跨瀨戶內海連接本州和四國島。

The bridge, which opened on May 1, 1999, carries two lanes of traffic in each direction and
has additional lanes for bicycles,motor bikes, and pedestrians.
這座橋，由此拉開1999年5月1日，承載的流量在每個方向兩個車道，並有額外
的車道自行車，摩托車和行人。

The Tatara Bridge was originally planned as a suspension bridge in 1973. In 1989, the design
was changed to a cable-stayed bridge with the same span. By building a cable-stayed bridge a
large excavation for an anchorage would not be needed, thereby lessening the environmental
impact on the surrounding area. The steel towers are 220 metres (722 ft) high and shaped like
an inverted Y. The side-spans are 164.5 metres (540 ft) and 257.5 metres (845 ft) respectively,
and there are also three very small cable spans.
多多羅大橋原本規劃為1973年的吊橋，在1989年，設計變更為斜拉橋。通過建
立一個斜拉橋不會需要大量開挖錨地，從而減少對周邊地區的環境影響。鋼塔
220米（722英尺）高，形狀像一個倒置的Y的邊跨度是164.5米（540英尺），
257.5米（845英尺）。

Construction of the bridge took a little more than six years and was accomplished without
any accidents. Many technological advancements were part of the design and testing of the
bridge.
橋樑的建築花了一點六年多，並完成沒有任何意外。許多技術是橋樑的設計和
測試的一部分。
