Wulidun Overpass

Wulidun overpass is located in the west of Hefei City, at the junction of Changjiang West Road, Tunxi Road and Hezuo Hua Road, 2.6km away from the city center. It is the first high standard highway overpass in Anhui Province, and has become a magnificent landscape on the first ring road of Hefei city. The overpass is divided into three floors above the ground and one floor under the ground, covering an area of 40000 square meters and 8.9 hectares. It is a four story interchange with double "Y" directional plus ring ramp. It is divided into five intersections and radiates around, solving the traffic problems of 17 directions. The whole bridge is novel and elegant in design, beautiful and fluent in appearance, reasonable and perfect in function, and magnificent in momentum. The Gaoliang bridge on the highest floor is 21 meters high from the ground floor and more than 11oo meters long. The whole bridge is connected vertically and horizontally, extending in all directions, like more than a dozen giant dragons crossing the river and the sea, giving people a sense of beauty. Wulidun overpass has invested more than 200 million yuan. Now it has become a "tree image project" of Hefei and even Anhui Province, and it is also an important symbol of Hefei moving towards a modern big city.

Wulidun overpass has invested more than 200 million yuan. Now it has become a "tree image project" of Hefei and even Anhui Province, and it is also an important symbol of Hefei moving towards a modern big city. On the morning of January 3, 2014, the reporter learned from the press conference held by the municipal engineering management office that a pier bearing of wulidun overpass A3 ramp (South 1st ring west viaduct) is aging and deformed, which needs to be replaced and will be closed for 110 days.

At 0:00 on April 10, ramp C3 of wulidun overpass (Hezuo Hua Road middle Changjiang Road) was opened to traffic. Learned from the municipal authorities, at 0:00 on the 15th of this month, A3 ramp (South 1st ring road to Changjiang West Road) will also be opened to traffic. At that time, all roads in all directions of wulidun overpass closed due to maintenance construction will be reopened.

Brief introduction of overpass

Wulidun overpass is located in the west of Hefei City, at the junction of Changjiang West Road, Tunxi Road and Hezuo Hua Road, 2.6km away from the city center. It is the first high standard highway overpass in Anhui Province, and has become a magnificent landscape on the first ring road of Hefei city. The overpass is divided into three floors above the ground and one floor under the ground, covering an area of 40000 square meters and 8.9 hectares. It is a four story interchange with double "Y" directional plus ring ramp. It is divided into five intersections and radiates around, solving the traffic problems of 17 directions. The whole bridge is novel and elegant in design, beautiful and fluent in appearance, reasonable and perfect in function, and magnificent in momentum. Gaoliang bridge, the highest floor, is 21 meters high from the ground floor and more than 1100 meters long, known as Wuli Feihong. The whole bridge is connected vertically and horizontally, extending in all directions, like more than a dozen giant dragons crossing the river and the sea, giving people a sense of beauty. Wulidun overpass has invested more than 200 million yuan. Now it has become a "tree image project" of Hefei and even Anhui Province, and it is also one of the important signs of Hefei moving towards a modern big city.

history

In the spring of 1995, Hefei clearly proposed to build itself into a modern big city. The city should extend to a wider area. With the widening of Changjiang Road, Hefei began the third "big construction" and extended to the old city for the first time. Soon after, the first ring road of 16.8 km and the second ring road of 42.2 km were started one after another, and a place called "wulidun" began to become the talk capital of Hefei people. Wulidun got its name because it was five li away from the city. In modern society, wulidun has gradually become a bus stop, but the traffic jams and frequent traffic accidents have made wulidun the "bottleneck" of traffic in Western China. This situation began to change in the summer of 1995. At that time, Hefei invested 260 million yuan to build wulidun overpass with a total length of more than 1100 meters. This is the first high standard highway overpass in Anhui Province, and its scale was the first in East China and the fourth in China at that time. Once put into use, this huge building greatly improved the traffic conditions at that time, and it also became the landmark of the third "great construction".

At that time, it was also said that the construction of such a large overpass was a "fuss". It was better to build two or three simple overpasses. However, many experts predict that the project will not really play its role until 15 years later. Sure enough, if there is no wulidun overpass, the traffic in the west of Hefei today is unimaginable.

effect

Wulidun overpass, as the first viaduct in Hefei, has also attracted the attention of many experts in 1995. Jiang Changzheng, director of the Department of architecture of Anhui Institute of architecture and technology, believes that the viaduct not only shows the new image of Hefei, but also marks that the traffic of Hefei will enter the era of "three-dimensional traffic" from "plane traffic".

Jiang Changzheng believes that in the past, the urban development pattern of Hefei was a "fan leaf shape", and the whole city was divided into three parts: the East, the southeast and the north. When the scale of the city is small and the traffic demand is not very strong, this kind of urban form is very beneficial to the development of the city. However, when the city develops to a certain scale, this "fan leaf" urban form can not meet the needs of urban development, and transportation has become the bottleneck of urban development.

With the rapid development of economy in the southwest of Hefei, Hefei has been closely connected with counties and cities in the southwest, including Feixi, Tongcheng and Anqing. Jinzhai Road, South Hezuo road and middle Changjiang Road are carrying more and more traffic pressure, with serious road damage and huge traffic risks. The pace of urban development has also been greatly restricted. The first ring road, the second ring road and even more ring roads can not keep up with the development of Hefei, and the plane traffic has fallen into a backward state. Hefei has been using the "two ring and nine shoot" transportation grid bureau can not meet the urban expansion, especially the expansion of Feixi Shangpai, Hefei Economic and Technological Development Zone, University Town and other external groups. It is becoming more and more urgent to connect the inside and outside of the city and directly open up a "road".

On the basis that the existing road is not enough to bear the function of urban rapid logistics, wulidun overpass is undoubtedly a pioneering work. Wulidun overpass is the first real express channel in the history of urban construction in Hefei. After completion, it will greatly reduce the driving time of Hefei southbound channel and improve the traffic carrying capacity of the southbound channel. It is a milestone in the history of Hefei's road traffic architecture.

Jiang Changzheng has repeatedly stressed that if a city can not gather and disperse the flow of people and logistics at the fastest speed, many problems will arise in the city. In terms of the city's lack of vitality, the stamina of the city's development will be insufficient. Although Jintun overpass, meitun overpass and other air traffic have alleviated traffic to a certain extent, their role is limited to a certain point. After the wulidun overpass is double connected, one bridge flies, which not only solves the traffic problems of Changjiang Road, but also considers the traffic pattern of Hefei. Wulidun overpass is not only the first viaduct in Hefei, but also the symbol of the transition from plane traffic to three-dimensional traffic.

Wulidun overpass is the "air highway" with the largest investment scale in Hefei city and even Anhui Province. The viaduct will soon be connected, and the light rail and subway in Hefei will also be put on the agenda. The prospect of urban traffic is bright. Wulidun overpass has set up a new pattern of three-dimensional traffic network in Hefei. Jiang Changzheng said that rail transit is far superior to traditional buses and automobiles in terms of traffic volume, speed and operation mode. The transportation capacity of subway is 7-10 times larger than that of ground buses. One way transportation can transport 40000-60000 person times per hour, and light rail transportation can transport 20000-30000 person times per hour. As Hefei, it is an indisputable fact that the pressure of road traffic on the ground is increasingly severe. The traffic can only develop in both directions of air and underground. Elevated and rail transit are the fundamental ways to solve this problem.

development planning

Wulidun overpass in Hefei, Anhui Province, has been used for many years. At present, the pavement is seriously damaged. Hefei Municipal Administration Office is going to carry out comprehensive maintenance on it. A few days ago, public bidding was carried out for the engineering design project.

Wulidun overpass is the first urban highway overpass in Anhui Province. It has been nearly 12 years since it was built and put into use in 1996. After years of use, wulidun overpass bridge is seriously damaged. In the road section of Changjiang West Road overpass, potholes, asphalt delamination and cracks can be seen from time to time on the road surface. In some places, the continuous damage is as long as 12 meters.

According to the preliminary statistics of wulidun overpass, more than 6000 square meters of road surface have been damaged. In addition to the continuous low temperature, ice and snow weather in early 2008, the asphalt surface of the overpass has not been systematically repaired since its completion, resulting in serious aging of asphalt pavement. While cleaning the bridge, the staff of Hefei Municipal Engineering Management Office replaced all kinds of "more modern" lamps and exterior decorations for the landmark old overpass. For a long time, due to the service life, bridge vibration and erosion of natural factors, some lamps on the bridge have been aging and damaged. In view of this situation, Hefei Municipal Administration Office started the "face washing" of wulidun overpass
