As a node project of the second ring road of the city, the bridge started construction on July 3, 2008, and was opened to traffic on July 20, 2008.
abstract
Wuhan Erqi Yangtze River Bridge is the seventh Yangtze River Bridge in Wuhan, Hubei Province. It is located 3.2km downstream of Wuhan Yangtze River Bridge and 7km upstream of Tianxingzhou Yangtze River Bridge. It is a super-large Yangtze River Bridge on the Second Ring Road in Wuhan. It starts from Wu Tiexin Jiang 'an Community in Jiang 'an District in the north and ends at Luojiagang, Governor Garden in Qingshan District in the south.
Wuhan Erqi Yangtze River Bridge designed by China Railway Bridge Survey and Design Institute is a three-tower cable-stayed bridge with two main spans of 6 16 meters. It is the world's largest three-tower cable-stayed bridge and the world's largest composite beam cable-stayed bridge. The total length is about 6.5 kilometers, of which the main project of Erqi Yangtze River Bridge is 2,922 meters, and the supporting relief projects on both sides are 3,585 meters.
The engineering design reference period is 100, which is an urban expressway with six lanes in both directions and an effective width of 28 meters. The clearance height of the bridge is 24m, and the designed maximum navigable water level is 25.8 1 m.. It is estimated that the total investment of the project is about 4.8 billion yuan.
According to the approved scheme, the design length of the bridge is 6507 meters, of which the main bridge is 2922 meters. The navigation hole (main span) of the main bridge adopts the scheme of three-tower cable-stayed bridge, and the span of double main holes is 2x616m. The approach bridge adopts viaduct scheme, with a total length of 3,585 meters, including 2,775 meters in Hankou section and 8 10 meters in Wuchang section. At the intersection of Erqi Yangtze River Bridge, Jiefang Avenue and Heping Avenue, there is an interchange.
According to the plan, the bridge project connects Hankou Development Avenue in the north and Wuchang Peace Avenue in the south. Jiangbei routes the down line of Beijing-Guangzhou Railway, passes Jiefang Avenue, Jiang 'an Freight Yard Railway Relief Zone, crosses the Yangtze River, passes through Wuchang Luojiagang Pumping Station, and goes along Luojiagang Drainage Channel to Heping Avenue.
The bridge type is a three-tower cable-stayed bridge with a design speed of 80km/h, eight lanes in both directions and a deck width of 29.5 meters. The project is estimated to be 2.8 billion yuan. The total investment of the project is 4.772 billion yuan, and the planned construction period is 4 years. Construction started on July 1 2008 and was completed and opened to traffic on February 3 1 20/2008.
The bridge was opened to traffic on 20 1 1, 12, 3 1. After the bridge is opened to traffic, the Zhuyeshan Interchange in Wuhan Second Ring Road and Heping Avenue Interchange will be connected into an urban expressway, and a river-crossing expressway will be added in Qingshan, Wuchang and Hankou areas.
The Erqi Yangtze River Bridge project aims to open Wuhan Second Ring Road as soon as possible and further improve the river crossing capacity.
design
preplanning
Minimize the interference factors of site selection.
After repeated research, the site and bridge type of Erqi Yangtze River Bridge are carefully selected from several schemes, especially considering reducing the demolition amount, minimizing the disturbance coefficient and paying special attention to environmental protection.
In the expert's argument, there are three sets of bridge-building route schemes: scheme one is from Xuzhou Ercun to Shuichang Road, from the south side of Erqi Memorial Hall, through Jiefang Avenue and Jiang 'an Freight Yard, and then across the Yangtze River to Wuchang Shuichang Road to Heping Avenue; The second plan is from Xuzhou Second Village to Luojiagang. The first half is basically similar to the first scheme, but after crossing the river, it passes through Luojiagang Pumping Station in Wuchang and goes along Luojiagang Drainage Channel to Heping Avenue. The third scheme is from Houhu Shipyard to Luojiagang, along the down line of Beijing-Guangzhou Railway, through Jiefang Avenue and Jiang 'an Freight Yard Railway Relief Zone, across the Yangtze River at Houhu Shipyard, through Wuchang Luojiagang Pumping Station, and along Luojiagang Drainage Channel to Heping Avenue.
Through demonstration, it is found that the impact of scheme 3 on the environment is relatively small. In particular, the minimum amount of house demolition has little impact on urban land use, and the construction noise has the least impact on residents. The houses along the bridge site are all 25 meters away. All bridges near residential areas are equipped with sound insulation walls to minimize noise pollution to residential areas.
After opening to traffic, the surrounding residents are basically unaffected by the exhaust of driving cars.
The other two schemes, in addition to Hankou traffic reconstruction, also occupy the Yujiatou campus of Wuhan University of Technology, and the supporting expenses are relatively large.
Jiangbei Jiangnan Gaojian He Jia junction
The Erqi Bridge will build viaducts and overpasses in Jiangnan and Jiangbei. Jiangbei approach bridge is an elevated bridge, which is connected with the main bridge of Erqi Yangtze River Bridge and the viaduct of the second ring road of Development Avenue. The total length is about 2820. 189 meters, and the viaduct is 26 meters wide with six lanes in both directions. At the same time, the construction of Jianshe Avenue Interchange and Jiefang Avenue Interchange, the construction of connecting ramps across canals, and the underpass of Beijing-Guangzhou Railway. In Jiangnan, Heping Avenue Interchange and Tsinghua Road Interchange will be built to connect the two main roads.
Bridge-type love three-tower cable-stayed bridge
Erqi Yangtze River Bridge is a three-tower cable-stayed bridge, which is not only the seventh bridge on the Yangtze River in Wuhan, but also the fifth cable-stayed bridge in Wuhan. Cable-stayed bridge is favored in Yangtze River bridge construction because of its large span capacity, beautiful appearance and low cost.
The Wuhan Yangtze River Bridge under construction and completion is mainly divided into cable-stayed bridges, suspension bridges and steel beam bridges, among which there will be five cable-stayed bridges.
In the selection of the main bridge type of Erqi Yangtze River Bridge, the design unit put forward five schemes: single main span steel truss arch bridge (main span 616m), double main span steel truss arch bridge (main span 2× 616m), double main span steel truss arch bridge and twin-tower steel box girder cable-stayed bridge (main span 7 10/0m).
The three-tower cable-stayed bridge is chosen mainly because of its smooth line shape and beautiful shape. The three towers are the same height, which implies the meaning of "three towns" in Wuhan. The beautiful scenery of "Three Towers Arch Bridge" first appeared on the Yangtze River in Wuhan.
Support scheme
Double-decker interchange diverts cross-river vehicles.
After the completion of the Erqi Yangtze River Bridge, how can the two sides quickly divert the rolling traffic across the river? Yesterday, the Wuhan Municipal Construction Committee announced that the supporting scheme for Hangang of Erqi Yangtze River Bridge was released, which will support the construction of interchange and expressway, and divert cross-river traffic in all directions. Different from the past, in the extension from Jiefang Avenue to Jianshe Avenue, a double-deck bridge interchange will be built on the main line.
According to reports, the primary function of the Erqi Yangtze River Bridge is to adapt to the rapid growth of urban river-crossing traffic and ease the pressure of river-crossing traffic in the central city. After completion, the daily traffic volume will be 55,000 vehicles, which will bear 15% of the river-crossing traffic volume.
According to reports, the Erqi Yangtze River Bridge will build supporting projects to divert huge traffic flow. The supporting project is connected to Hankou Development Avenue in the north and Wuchang Peace Avenue in the south. The length of reconciliation wiring on the north bank is 2775m, and that on the south bank is 8 10/0m. Engineering estimate181800 million yuan. The technical level of the main line of the project is urban expressway, the calculated driving speed is 80 km/h, and the number of lanes adopts two-way six lanes.
Features: Double-deck interchange diversion
Wuhan Municipal Design Institute showed the scheme of "Wiring Engineering Design of North Bank (Hangang) of Wuhan Erqi Yangtze River Bridge".
According to reports, the main line of the Hangang supporting scheme of Erqi Yangtze River Bridge is a full-line viaduct type, starting and ending at the main bridge of Erqi Yangtze River Bridge and the viaduct of the second ring road of Development Avenue, with a total length of about 2,820 meters, a viaduct width of 26 meters and six lanes in both directions. The main line of the extension from Jiefang Avenue to Jianshe Avenue is a double-deck bridge. This can divert the cross-river vehicles faster.
Along the line of this project, it intersects with traffic trunk roads such as Jianshe Avenue Extension Line, Jianshe Canal Road, Jiefang Avenue and planned Jiang Yan Road respectively, and sets up Jianshe Avenue Interchange, Jiefang Avenue Interchange, Construction Canal Crossing Ramp, and underpasses Beijing-Guangzhou Railway Passage, etc. The red line width of the ground auxiliary road project is 25m-80m.
Cost: The supporting investment is 325 million yuan.
According to the introduction of Wuhan Design Institute, the supporting project of Hangang Erqi Yangtze River Bridge costs about 325 million yuan. After the completion of the supporting project, the rolling traffic of Erqi Yangtze River Bridge will be gradually diverted to the central city of Hankou.
According to reports, the Erqi Yangtze River Bridge is scheduled to start construction this month with a total investment of 4.227 billion yuan. Upon completion, it will be the seventh Yangtze River Bridge planned and constructed in Wuhan, and it will also be the eighth river-crossing passage on the Yangtze River section in Wuhan. The bridge was completed and opened to traffic at the end of 20 1 1. Residents of Houhu Lake in Hankou can go to Wuchang, and they can go to Erqi Yangtze River Bridge through the extension of Development Avenue without crowding the Second Yangtze River Bridge.
scale
The most "fashionable" bridge
Looking at the renderings again, I can see that the Erqi Yangtze River Bridge is like a long dragon lying on the waves, with bright spots shining. The whole bridge has a smooth outline and beautiful shape. The stay cable is like an unfolded giant umbrella, and the three towering towers symbolize the "three towns" in Wuhan.
Gao said that there are many bridges in Wuhan and it has the reputation of "Bridge Museum". There are twin-tower cable-stayed bridges, twin-tower suspension bridges, arch bridges and continuous structural bridges, but there are no three-tower cable-stayed bridges. With the construction of the Erqi Yangtze River Bridge, the "Bridge Museum" in Wuhan will add "new members" to enrich the bridge culture in Wuhan.
What's more worth mentioning is that Erqi Yangtze River Bridge is the largest three-tower cable-stayed bridge in the world, with a main span of 6 16 meters. In addition, the tower of Erqi Yangtze River Bridge is 205 meters high, which is 9 meters higher than the Tianxingzhou Yangtze River Highway and Railway Bridge under construction. It is the tallest bridge in Wuhan.
According to reports, many bridge experts have devoted a lot of efforts to the bridge type of Erqi Yangtze River Bridge. Academician Fang Qinhan and Academician Jin Yang, masters of bridge design, have made dozens of field visits since-1979, and have successively referred to the bridge types of many world-famous bridges such as Greek Leon Bridge, and introduced and digested many advanced bridge-building concepts at home and abroad.
The most affordable bridge
When planning to build the Erqi Yangtze River Bridge, * * * had five schemes, why did you finally choose the three-tower cable-stayed bridge? The high introduction is mainly due to the considerations of navigation, economy and practicality.
Among the existing Yangtze River Bridges in Wuhan, the first bridge is 6.8 kilometers away from the second bridge, the second bridge is more than 9 kilometers away from Tianxingzhou Bridge, and the second bridge is only 3.2 kilometers away from Erqi Bridge. This short distance makes it too short for the ship to adjust its attitude. Therefore, the final scheme determines that the bridge type is double main holes, which has a large room for ship adjustment.
A double-span bridge can be an arch bridge or a cable-stayed bridge. At that time, many experts suggested taking an arch bridge with better landscape effect. However, the National Development and Reform Commission, Planning Bureau and other experts believe that the three-tower cable-stayed bridge is a cable-stayed bridge, because the cable-stayed bridge technology has matured in Wuhan. Although there is no shortage of cable-stayed bridges in Wuhan, there are no three-tower cable-stayed bridges. In contrast, arch bridge construction is difficult, and the price of steel rises, so the arch bridge with large steel quantity is expensive. The three-tower cable-stayed bridge designed by the bridge courtyard has a beautiful outline, especially the towering three towers, which have distinctive Wuhan characteristics (meaning three towns in Wuhan). Finally, Wuhan finally decided to adopt the three-tower cable-stayed bridge for Erqi Bridge.
It is estimated that after the Erqi Bridge adopts the three-tower cable-stayed bridge, the main bridge and supporting projects on both sides of the strait will need to invest about 4.26 billion yuan, which is lower than the cost of arch bridge and suspension bridge, reflecting the principle of economic, practical and reasonable bridge construction. If you build a cable-stayed bridge with twin towers, the cost will be more expensive.
In addition, the selection of the three towers is very convenient for ships to pass, and the two main spans are 6 16 meters, which meets the navigation standard of 575 meters.
The bridge with the shortest construction period
According to reports, Erqi Bridge chose the three-tower cable-stayed bridge because of its mature technology and convenient construction. Wu Hanyou's two major bridge-building corps, China Railway Bridge Bureau and China Communications No.2 Navigation Bureau, have strong cable-stayed bridge construction capabilities. They built Sutong Yangtze River Bridge, the largest cable-stayed bridge in the world, and Hangzhou Bay Bridge, the largest cross-sea bridge.
This is very important, because the Erqi Yangtze River Bridge is in a hurry, and the construction period is set at -3 years, so the time is very tight.
The reason for the urgent time to build the bridge is that the traffic pressure in the central city of Wuhan is getting heavier and heavier, and the Second Yangtze River Bridge has been overloaded for a long time. In view of the urgency of diverting the traffic pressure of the Second Yangtze River Bridge, the construction period of Erqi Bridge is short.
According to relevant sources, the urban pattern of the intersection of the two rivers and the division of the three towns has led to a long-standing contradiction in cross-river traffic in Wuhan, and cross-river traffic has always been the primary problem in Wuhan.
The number of river-crossing passages in Wuhan is very limited. There are only three river-crossing bridges on the Yangtze River in the main urban area, with a total of 16 lanes and a total design capacity of about150,000 vehicles/day. According to the cross-river traffic flow survey in 2007, the total traffic flow of the Yangtze River Bridge reached 85,000 vehicles (single and even traffic control), and the total traffic flow of the Second Yangtze River Bridge reached 10 vehicles. The supply of urban river-crossing passages is seriously insufficient, and the traffic flow across the river is mainly concentrated on the Yangtze River Bridge and the Second Yangtze River Bridge in the central area (in 2007, the traffic volume of these two bridges accounted for 8 1. 1% of the total traffic volume across the river in the main city), which makes the traffic volume of these two bridges in a supersaturated state.
The bridge deck of Erqi Bridge is slightly wider than that of the Second Yangtze River Bridge, with six lanes in both directions and a design speed of 80 kilometers per hour ... It will effectively divert the traffic pressure of Wuhan Yangtze River Bridge, and it is estimated that 15% of the traffic will be diverted to Erqi Bridge.
The bridge with the strongest displacement resistance
Suspension bridges, cable-stayed bridges, rainbow bridges ... There are more and more river-crossing bridges in Jiangcheng, which are lighter and more beautiful. However, in recent years, the newly built bridges in Jiangcheng have become more and more fragile. In recent years, many bridges in Wuhan have undergone "major operations".
Some bridge experts said that the reasons for the "short life" of today's bridges involve many links such as design, construction, use and maintenance. Limited by the technical conditions at that time, the structural design was unreasonable, overloaded vehicles were repeatedly crushed, and the traffic volume exceeded the original design load, but the steel box girder and concrete could not be well bonded, resulting in "displacement", which was one of the important reasons for the repeated overhaul of bridges (such as Baishazhou Yangtze River Bridge) and also a worldwide problem.
On the 29th, the person in charge of the bridge institute introduced that in order to solve this problem well, the Erqi Bridge has thought many ways in its design, such as adopting composite beam structure and adding more than 300,000 groups of shear studs on the steel surface, so that the concrete and steel box girder can be more firmly bonded together, ensuring the bridge quality to the maximum extent and reducing the overhaul of the bridge.
The strongest bridge
According to Gao, the Erqi Yangtze River Bridge will be the strongest bridge in Wuhan after its completion. Its design life is 100 years, and the road grade is urban expressway, which can resist the flood once in 300 years.
In design, the seismic function of Erqi Bridge is also strengthened. Although the probability of an earthquake in Wuhan is very small, Erqi Bridge can withstand an earthquake of magnitude 7 once in 2000. In addition, the three piers firmly standing in the middle of the river have strong anti-collision ability, and the piers are still motionless under the impact of 5000 tons of seagoing ships.
affect
environmental protection
Does not affect the migration of rare aquatic organisms.
The environmental protection problems faced by the bridge construction mainly involve the impact on the water source, the impact on the spawning and migration of rare protected animals, the impact on residents near the bridge site and the impact on the Yangtze River.
It is reported that the environmental impact assessment of Erqi Yangtze River Bridge has passed the acceptance of the national environmental protection department.
The section of Erqi Yangtze River Bridge is the passage of many rare aquatic animals such as white dolphins. During the construction, observation posts will be set up at the peak of migration of white dolphins, finless porpoises, Chinese sturgeons and white sturgeons, and piling and percussion drilling operations will be stopped when animal activities are found.
The drilling residue and sediment generated in the construction will be concentrated on the dumping ship and treated as required, and shall not be discharged into the polluted waters in the river. All kinds of construction wastewater should also be collected and treated.
Among them, noise screens or windows will be installed in residential areas adjacent to the bridge; In order to reduce the noise of passing vehicles, the pavement of Erqi Yangtze River Bridge is designed as asphalt with the best noise reduction effect, with noise reduction of 5 decibels; According to the prediction of acoustic environment, the bridge site has been "moved" by 25 meters, keeping a proper distance from the settlement such as "Qingyang Liuhe".
According to reports, the bridge has formulated an emergency plan for transporting toxic and harmful chemicals, set up a rainwater collection system on the bridge deck, and set up rainwater and accident sewage treatment systems at both ends of the main bridge to prevent the water quality safety of the water intakes of Hankou Dijiao Waterworks and Wujiatou Waterworks in Wuchang.
traffic
Qingshan and Erqi areas can realize 80 km/h fast round trip.
After completion, the second bridge will be reduced by 18%.
As an important node project at the northern end of the Second Ring Road, after the completion of the Erqi Bridge in 2065438+2002, the North Ring Road of the Second Ring Road will be the first to connect and effectively divert the Second Yangtze River Bridge. Yesterday, the relevant person in charge of the Wuhan Municipal Planning Bureau said that after the completion of the Erqi Bridge, it will be beneficial to the uniform traffic flow across the river in Wuhan, revitalize the cross-river traffic in Wuhan and greatly improve the accessibility of traffic.
The flow of the second bridge is reduced by about 18%.
Because the distance between the Second Yangtze River Bridge and Tianxingzhou Yangtze River Bridge is about 10 km, the traffic flow across the river in Wuhan is very uneven. According to the statistics of relevant departments, the traffic volume of the Second Yangtze River Bridge is basically saturated, and the traffic volume of the five intersections with the largest traffic volume such as Hankou Aviation Intersection, Huangpu Intersection and Hanyang Cultural Palace Intersection exceeds 1 10,000 vehicles per hour.
According to the forecast, in 20 10, the total traffic volume of the Yangtze River crossing the river in the main urban area of Wuhan will reach 400,000 vehicles/day. If the Erqi Bridge and Yangsigang River-crossing Tunnel are not considered, the river-crossing traffic volume of the 1st and 2nd Yangtze River Bridges will be 20 1 1 10,000 vehicles/day respectively.
After the completion of Erqi Bridge, the daily traffic volume will be 55,000 vehicles, which will bear 15% of the river-crossing traffic volume. By then, the flow of the first Yangtze River Bridge will remain at the current level, the flow of the second Yangtze River Bridge will be reduced by about 18%, the flow of Tianxingzhou Bridge will be reduced by about 38%, and the flow of other river-crossing channels will not change much.
In addition, the construction of Erqi Bridge will establish more rapid and direct traffic links between Wuhan New Railway Station and 800,000-ton ethylene chemical new city and Hankou area.
The Second Ring Road and the North Ring Road will be the first to get through.
Affected by the river division, the road networks of the three towns in Wuhan are relatively independent, and the links between them are weak, which can not give full play to the overall functions of the city's road networks. Yesterday, the relevant person in charge of the Wuhan Planning Bureau said that after the completion of the Erqi Bridge, the urban road system in Wuhan will be improved, which is an important part of the urban traffic construction in Wuhan.
It is understood that the number of motor vehicles in Wuhan has continued to grow rapidly, with a total of more than 703,000 vehicles. The growth mainly comes from private cars, the total number of which has exceeded1920,000, an increase of about 7 times compared with 2000. The road mileage in the main urban area of Wuhan is about 2,369 kilometers, which is only less than double the 1332 kilometers in 2000. In order to meet the increasing traffic demand, it is necessary to open the ring network of the whole city as soon as possible.
The Second Ring Road planned and constructed in Wuhan is located between the central area of the city and the peripheral groups, with an average distance of about 3 kilometers from the inner ring and a total length of 52 kilometers. Mainly to reduce the traffic pressure across the river in the central area and reduce the number of vehicles passing through the central area.
At present, the Second Ring Road has built trunk roads with a standard length of about 29 kilometers, including Development Avenue, Han Xi Road, Shi Sheng Road and Luoshi Road.
As an important node project at the northern end of the Second Ring Road, Erqi Bridge will be the first to open the North Ring Road of the Second Ring Road after its completion in 2005. By then, Qingshan and Erqi can travel back and forth quickly at a speed of 80 km/h.
In addition, as an important node at the southern end of the Second Ring Road, Yangsigang River-crossing Tunnel is expected to be completed in 20 15.
economy
String up the Second Ring Road to revitalize 470 square kilometers of land.
When the Erqi Yangtze River Bridge is completed, it will be connected to Wuhan Second Ring Road like a pearl chain.
The average distance from Wuhan Inner Ring to Central Ring is about 9 kilometers, and the land area is about 470 square kilometers (including water). Only relying on the inner ring road and the outer ring road can not meet the needs of such a large regional city and traffic development, but it is necessary to add a fast ring road between the two rings, and the planning of the second ring road is put forward under this idea. The Second Ring Road will mainly provide transportation services for the city Expo Center, high-speed rail passenger station, sports center and new commercial and residential areas in the city.
According to the urban development and construction plan, the four residential new towns, Houhu, Sixin, Nanhu and Donghu, which were mainly developed during the Eleventh Five-Year Plan period in Wuhan, and the Wangjiadun commercial center are all located between the inner ring and the central ring.
After the completion of Erqi Bridge, it will truly connect Wuhan Second Ring Road like a pearl chain, which will greatly revitalize the 470 square kilometers of land in the Second Ring Road.
The reserve plots in Erqi area benefit first.
The Erqi Yangtze River Bridge is about to start, and people in Wuhan real estate industry are generally optimistic about the development prospects of this property located at the northern end of the Erqi Yangtze River Bridge.
According to industry insiders, after the Erqi Yangtze River Bridge starts, the land reserve plots in the Erqi area in the north of the Yangtze River will benefit first, and the land development in this area will continue to increase.
At present, many developers have settled in Erqi area. Following the development of Dongli International in advance, Wuhan Sanjiang Aerospace Real Estate has also developed a large market with an area of 200 mu and a total area of 400,000 square meters at the intersection of Jiefang Avenue and Erqi Road in Hankou. The average price of 8,200 yuan/square meter greatly exceeded the previous average price of 6,000 yuan/square meter in this area.
According to industry insiders, the northern end of Erqi Yangtze River Bridge belongs to Houhu Life Group planned by Wuhan, and the light rail line has already been opened, which has incomparable advantages over the southern end of Erqi Yangtze River Bridge in terms of living facilities, and the real estate prospect is more promising.
According to relevant departments, the distance between the Second Yangtze River Bridge under construction and Tianxingzhou Yangtze River Bridge is as long as 10 km, and the planned land area on both sides of the Yangtze River between the two bridges is nearly 70 square kilometers, with a large number of undeveloped areas and land to be developed. However, because there is no other crossing channel between the two bridges, the traffic connection between the two sides is very poor, which hinders the development of land on both sides of the Yangtze River.
Two residential new towns, Houhu and Donghu, which were built in Wuhan during the 11th Five-Year Plan period, are located at both ends of the Erqi Road crossing, and the construction of the Erqi Road crossing will greatly promote the development of land on both sides of the strait.
According to relevant research reports, the construction of Erqi Yangtze River Bridge will at least promote the appreciation of 70 square kilometers of land on both sides of the strait.
Wuhan real estate industry insiders said that because Qingshan District will focus on the construction of Yangchunhu City Sub-center with Wuhan Station as the fulcrum according to the plan, the developable land along the East Lake has been basically exhausted, and the impact of the construction of Erqi Yangtze River Bridge on the southern end of the bridge is far less than that of the northern end.
In addition, with the rise of oil prices, the number of people who need to buy cars and houses in this area will decrease. The radiation range of Erqi Yangtze River Bridge is estimated by relevant departments to be less than 70 square kilometers.
The northern end of the bridge will take the lead in forming the bridgehead business circle.
At the northern end of Erqi Bridge, developers are consciously building a bridgehead business circle. Wuhan real estate industry generally believes that after the completion of Erqi Bridge, the northern end of Erqi Bridge will form a bridgehead business circle before the southern end.
Hankou Oriental Shopping Park, which is being developed at the northern end with a total area of150,000 square meters, is one of the key commercial projects in Wuhan in 2007. Its overall commercial positioning is planned as a regional commercial center integrating shopping, leisure, entertainment and culture, which will radiate 500,000 people in three communities in northeast Hankou, and the retail giant Carrefour has preempted the layout.
According to industry insiders, according to the law, the formation of Qiaotou business district is inevitable. As far as the current situation is concerned, the northern end of Erqi Bridge will form a bridgehead business circle before the southern end.
In addition, some insiders said that the speed of Erqi Bridge has reached 80 km/h due to the planning and positioning of the bridge as a expressway system. Compared with Xu Dong, there may be a phenomenon that people are busy in the early stage, and the formation speed of business circle may be slower than that of Xu Dong business circle.
progress
On the first working day of 20 12, the traffic volume of Erqi Yangtze River Bridge was 1 1703, which was the most "leisure" river crossing channel in Wuhan. In contrast, the traffic volume of the Second Yangtze River Bridge reached 83,433 yesterday, and the busiest burden has not been significantly reduced. According to the traffic police's visual inspection in the morning, the average traffic volume of Erqi Bridge during peak hours is 20-30 vehicles per minute, which is significantly higher than the average traffic volume of about 5 vehicles per minute on the first day of opening to traffic. As of 4: 30 pm yesterday, the traffic volume of Erqi Yangtze River Bridge was 1 1703 vehicles, and it is estimated that the traffic volume will be around 20,000 vehicles throughout the day.
The supporting project has not been completed, and the diversion capacity has been greatly reduced. Shortly after the opening of the Erqi Yangtze River Bridge, many drivers still don't know how to cross it, and they are used to taking the Second Yangtze River Bridge. It is expected that after a period of operation, the traffic volume of Erqi Bridge will gradually increase, which can further share the traffic pressure of the Second Yangtze River Bridge.
