The in-construction Hong Kong-Zhuhai-Macau Bridge is a series of bridges and tunnels that will connect the west side of Hong Kong to Macau and the Guangdong province city of Zhuhai,which are situated on the west side of the Pearl River Delta.The proposed 50 km (31 mi) link is expected to cost US$10.7 billion.With its length,it would become one of the landmarks within the area.Though overall length exceeds the Second Lake Pontchartrain Causeway in the United States,which is 38.4 km (23.9 mi) long according to the Guinness Book of World Records,the longest bridge section (between the artificial islands containing the Macau exit of the tunnel and the Macau border facilities[1]),which will include three cable-stayed spans with spans between 280–460 m (920–1,510 ft),will be 22.8 km (14.2 mi) long.[2] Construction formally began on 15 December 2009.[3] It is due to be completed in 2015-2016. The bridge will benefit the economic development of the whole of the Delta.For Hong Kong,the project will enable the city to continue its status as an international aviation and shipping centre.The Bridge will also help realise the strategic benefits of promoting the socio-economic development of the western Pearl River.In linking up Hong Kong,Macau and Zhuhai,the bridge will form a systematic regional transport network and provide an overland link.This link will substantially shorten the travelling time between the eastern and western sides of the southern tip of the PRD.Faster economic integration between Hong Kong and the region is expected with the increasing flows of people,goods and even capital.With closer economic tie between Hong Kong and its neighbouring region,Hong Kong can assume a leading role in driving the economic development in South China. Chinese and Hong Kong leaders are able to hammer out the plans for a giant bridge linking Hong Kong to mainland China and Macau,a US$2 billion project driven by Beijing's desire to show the territory can thrive under its rule.The urgency[citation needed] Beijing has placed on the 29 kilometer-long bridge and quicker economic integration between Hong Kong and China was triggered[citation needed] by a July 1,2003 protest march when half a million Hong Kongers took to the streets to express their discontent with government.[citation needed] In promoting the Hong Kong-Zhuhai-Macau bridge and closer cross-border economic ties,Beijing is throwing a lifeline to economically battered Hong Kong. The bridge is the second major high-profile project between China and Hong Kong between June and August,2003.In late June 2003,the two signed a free trade pact - a Closer Economic Partnership Arrangement or called CEPA,further opening China to Hong Kong companies. 我这里正好有一篇,第一段是介绍港珠澳大桥的,后面的写的是它对香港发展的必要性,有点长,你可以自己删选一下,绝对是你要的
