Bead trigonometry area is our country economy most one of areas that develop, zhongshan is located in bead trigonometry on the west bank center position, but in the absense of railroad, airport and deep water harbor, and with east bank join is disadvantageous, area the advantage cannot be developed effectively all the time. Shenzhen and Zhongshan meet the economy of suddenly grows urgent need increasingly a quicker passage, with going to the lavatory two ground people is in economy, content sheds the close cooperation that waits for each respect. Below this setting, deep in passageway emerge as the times require. Deep in passageway circuitry makes an appointment with 24 kilometre endlong, the project invests 50 billion yuan, it is the big bridge of city of Shenzhen of join Guangdong province and Zhongshan city, it is world-class exceeds big " each other of the bridge, island, Sui, underground is connected " group project. On November 3, 2017, deep in design of graph of construction of passageway bridge engineering already was examined through the expert, bridge project will be in 2017 start working of essence of the end of the year, project construction will turn into the construction phase of materiality in the round, predict to built be open to traffic 2024. Deep in after passageway be open to traffic, the main thoroughfare that becomes bank of thing of join Pearl River, arrive directly at Shenzhen quickly from Zhongshan, connect diligent time by before 2 hours cut for 30 minutes. After passageway building, offerred a condition to attract big project to enter next. The construction window of this bridge is quite much. Among them, build a chunnel that grows about 7.1 kilometers, bridge grows about 16.9 kilometers, two end set channel each 1 place is artificial island. All fronts is used two-way construction of standard of 8 driveway freeway, design speed per hour 100 kilometers / hour. The project includes: Two artificial islands, east side island is 625 meters long, 100 meters wide; Side island grows 625 meters on the west, 175 meters wide; Channel of heavy tube strong point, 6720 meters long, the old water course that shovel a bay, airport is worn to raise Shi Shui of channel, Ji below; Bridge of lonely modern course, advocate cross headroom of 1620 rice, be open to navigation or air traffic 76 meters; Bridge of path of horizontal door Xi Hang, advocate cross headroom of 580 rice, be open to navigation or air traffic 53.5 meters. Artificial island island grows on the west it is 625 meters, submit kite form, the widest place 456 meters, land region tall Cheng is 4.9 meters, maritime space usable floor area is 253 thousand square metre, the area of insular put oneself in another's position with its go-between visible eye 137 thousand square metre, area of insular put oneself in another's position is equivalent to football ground of 19 international standard. Deep in passageway on the west artificial island project already at formal 2016 construction, the insular Sui project that the 2nd phase regards a key as circuit and control sex project will be in in December 2017 start working; Project of bridge of the 3rd phase plans in April 2018 start working, deep in passageway project plan built be open to traffic 2024. Deep in the passageway is returned will reach with the high speed of Shan crystal clear December 2017 in June 2018 of be open to traffic deep luxuriant railroad, and the passenger flow that opened the wide Zhan Gaotie that build 2018 forms amlposition operation, area people goes economic another name for Guangdong Province on the west a time, Look from blueprint, bridge paragraph made kite line, the hub stands hand in outline to resemble a string dish. "Arrowhead " the sky inside modelling building, use as in the center of monitoring room, both wings uses a room as equipment. Future, no matter people is in circumjacent, or by plane or when drive car reachs this area, can see passageway bridge and artificial island from different point of view.
