新加坡政府日前公布了一项极富想象力的计划——建造一座形似DNA（脱氧核糖核酸）的螺旋型大桥。新加坡政府的这一奇思妙想旨在大力推动本国旅游业的发展。
据路透社日前报道，这座“DNA”大桥耗资大约6800万新元（约合4057万美元），它建成后将是世界上首座如同DNA形状的大桥。新加坡政府说，大桥由6车道和6米宽的人行道组成，将于今年底动工，计划在2009年完工。
新加坡的目的是到2015年将游客量翻番，达到1700万人；旅游业收入将增加3倍，达到300亿新元，并新建两座游乐场和170米高的大型观览车以及完善附近名胜区圣淘沙岛的建设。
报道说，在有着440万人口的新加坡，旅游业的创收超过国内生产总值的5％。
Singapore Monday unveiled an audacious plan to build a helix-shaped bridge that will link a massive new tourist development, including a giant Ferris wheel and casino complex on reclaimed land.
The bridge, which will cost around S$68 million, is believed to be the world's first to resemble the structure of DNA, the genetic material.
Singapore aims to double visitor arrivals to 17 million and triple tourism receipts to S$30 billion by 2015 with new projects such as two planned casino-resorts and a 170-meter high (558 feet) Ferris wheel.
The nearby resort island of Sentosa is also being developed.
Tourism is one of the biggest service industries in the city-state of 4.4 million people, generating more than 5 percent of gross domestic product.
The government said construction of the bridge, consisting of a six-lane motorway and six-metre wide pedestrian walkway, will begin at the end of the year and is targeted for completion in 2009.
