Reconstruction of Chengdu First Ring Road

165438+1On October 30th, the city will start the construction of three-node interchange of Ximen Station, Yangxi Line and Goldman Sachs Bridge on the First Ring Road. Three two-way four-lane node interchanges are overpass bridges in the direction of the First Ring Road, which is the biggest reconstruction construction since the completion of the First Ring Road. Four months later, that is, before the end of 20 1 1 March, these three node overpass bridges will be completed and opened to traffic.

According to the relevant person in charge of the Chengdu Municipal Communications Commission, at the beginning of the planning and construction of these three overpasses, corresponding traffic flow experiments were carried out. The simulation experiment shows that after the overpass is built at Ximen Station, Yangxi Line and Goldman Sachs Bridge of the First Ring Road, the traffic flows on these out-of-town passages will no longer meet, but the traffic flow of the First Ring Road can be directly improved by the diversion of the upper span. After the completion, the vehicles on the First Ring Road will cross the Goldman Sachs Bridge. When you get to the provincial hospital, you can take the existing underpass tunnel, the Yangxi Line and Ximen Station, then take these two viaducts to be built, and then continue to walk along the First Ring Road and get on the existing Shawan Road overpass bridge. It can be said that in the future, the whole intersection in the western half of the First Ring Road will no longer be blocked by red lights and can continue to pass at high speed.

After the completion of the three-node overpass, there will be six separated overpasses in the west and south of the first ring road in our city, including Shawan Road, Ximen Station, Yangxi Line, Chengdu University of Traditional Chinese Medicine, Goldman Sachs Bridge and Yiguan Temple. More than half of the important nodes of the First Ring Road will realize transfer, thus greatly alleviating the traffic congestion in the western area and greatly improving the circular traffic of the First Ring Road.

At 5 o'clock in the afternoon yesterday, the Chengdu Evening News reporter came to the intersection of Ximen Station on the First Ring Road and saw a long queue of vehicles leaving the city for about one kilometer. The road traffic police told reporters that there are often traffic jams in the morning rush hour 1 to 2 kilometers, and in the evening rush hour 1 to 2 kilometers; The traffic conditions are basically the same at the intersection of Yangxi Line of the First Ring Road and Gaoshengqiao East Road of the First Ring Road.

In order to alleviate congestion and ensure smooth traffic, the third batch of ***2 1 footbridges will be started in time on 20 1.

According to reports, the 265 and 438+0 overpasses to be built in this batch are located at the intersection of Nanjie-Hongzhaobi, Dongcheng Gen Street-Shaanxi, Chunxi Road-Southwest Bookstore, Dongjie-Qingshiqiao, First Ring Road-Wenhua, Renmin North Road-Xiaosi Lane, Laochengguan Road-Olympic Park, Xiaonan Street-Jiabao Lane and Changshun Shang Jie-Kuanzhai Lane.

It is also known that in 20 1 1 year, the Municipal Construction Committee will also start the full interchange reconstruction of three overpasses on the Third Ring Road, namely Wuhou, Cao Jin and Shiling, as well as major projects such as overpasses around Freight Road and Guanghua Avenue.

"This construction can be called the most extensive traffic impact in Chengdu's traffic history. After the construction starts, the traffic in the southwest will be quite fragile, which may lead to regional traffic congestion if you are not careful! " Zhou, deputy section chief of the Optimization Department of the Traffic Management Bureau of the Municipal Public Security Bureau, told reporters yesterday that the traffic in the southwest of Chengdu will endure four months of pain.

According to Zhou, some time ago, they made some estimates. After the third bridge starts construction, the traffic capacity of the first ring road intersection and road section will be reduced by about 33% and 50% respectively. According to the flow analysis, there are 9 radioactive roads in Ximen area, such as Shawan Road, Laochengguan Road, Yangxi Road, Qingjiang Road, Tsinghua Road, Dashi Road, Wuhouci Street, Yongfeng Road and Cao Fang Street, which are all saturated and have weak diversion capacity. The decrease of traffic capacity will aggravate the traffic pressure in the south and north ring roads. "The congestion will be more serious, and the queue will increase exponentially. The estimated maximum length is 1km!"

As the main diversion road, the western half of the Second Ring Road will further increase the traffic pressure. There is no widening space for the intersection construction sections involved in the three overpass bridges. In addition, after the construction, non-motor vehicles and pedestrians will also increase the interference to the traffic of motor vehicles, which will greatly reduce the traffic capacity of roads and areas involved in the construction intersection.

Zhou mentioned that the traffic volume in Ximen area has always been the largest in Chengdu. Without road construction, there will be traffic jams in the morning and evening rush hours. According to their calculation, during the subway construction, the traffic volume of 5000~6000 vehicles per hour at each intersection in Ximen area of the First Ring Road is normal. Take the overpass bridge at the intersection of West Yard on the Second Ring Road as an example. In the construction stage, vehicles entering and leaving the city in Ximen area need to bypass, and the traffic situation is quite painful when they encounter traffic jams. "Subway construction and overpass construction are carried out at the same time. In the event of a traffic accident in bad weather such as vehicle scraping, rain, fog, etc., it is very likely to cause regional traffic congestion! "

"Long pain is better than short pain!" According to the relevant person in charge of the Propaganda Department of the Traffic Management Bureau of the Municipal Public Security Bureau, the construction of any one of the three overpass bridges will greatly increase the traffic pressure in the First Ring Road and Ximen area, and it will not be less than the traffic pressure brought by the simultaneous construction of the three bridges. Strengthening the construction progress and building three overpass bridges simultaneously can reduce the traffic pressure in Ximen area in time span. After the three overpass bridges of the First Ring Road are completed and opened to traffic, the road network in the southwest area of the First Ring Road will be formed, which can improve the traffic efficiency of the whole First Ring Road and the traffic efficiency of vehicles entering and leaving the city at corresponding intersections.

The person in charge said that after the completion of the three overpass bridges in the West Half Ring Road, the quasi-continuous traffic capacity will be formed in the west and south of the First Ring Road, creating conditions for the formation of large-capacity, continuous and rapid traffic on the west side of the city, which is of far-reaching significance. At the intersection of Ximen Station and Yangxi Line of the First Ring Road, I suddenly saw a sign that no left turn was allowed, and the driver stopped at the intersection. There are many pedestrians and non-motor vehicles in the construction gap section, and the motorway is not wide ... Yesterday was the first day of the construction of three overpass bridges on the First Ring Road, and there were many chaotic phenomena in the traffic on the construction section. The traffic police reminded the citizens who drive to work that they must be familiar with the route, so as not to find the direction and miss the working hours.

The traffic police reminded that citizens who need to go through the construction section should go out early for work next Monday. In the next four months, vehicles that need to pass through Ximen Station of the First Ring Road, Yangxi Line and Gaoshengqiao Road can bypass Shawan Road and Jiulidi South Road, as well as Glory Community, Father Southwest Street Community, Guangfuqiao Community and Keyuan Road Community.

The relevant person in charge of the Regulation Section of the Traffic Management Bureau Branch of the Municipal Public Security Bureau said that this situation was expected yesterday. They are worried about the traffic in the west gate area of Huancheng Road next Monday. They are currently observing the latest traffic changes in order to try their best to cope with the morning rush hour next Monday. In addition to continuing to send additional police forces at each intersection to divert traffic, the traffic police may also take measures such as adjusting motor vehicle lanes and non-motor vehicle lanes and adjusting the timing of traffic lights in nearby sections according to traffic conditions.

The three radioactive roads that intersect with the three overpass nodes of the First Ring Road, namely Ximen Station, Yangxi Line and Goldman Sachs Bridge: Yingmenkou Road, Yangxi Line and Wuhouci Street, have intermittent traffic jams, and the traffic peak starts from yesterday morning 10, and vehicles often line up for 200-300 meters. By 7: 30 in the evening, some readers still called the hotline of this newspaper, claiming that they were blocked.

Yesterday morning 10, the reporter saw at the intersection of Ximen Station that Huapaifang Street went out of the city because it didn't adapt to the new traffic changes, and the congested vehicles lined up for nearly 300 meters. There are also many pedestrians and non-motor vehicles crossing the First Ring Road from the motorway. The traffic police increased their police force at the intersection.

The reporter pointed out that it is forbidden to leave around the intersection of Ximen Station on the First Ring Road. On the south side of the First Ring Road, pedestrians and non-motor vehicles cross the street from the crosswalk outside the construction area; On the north side of the First Ring Road, pedestrians and motor vehicles need to cross the street from the crosswalk in the construction area.

10: 50, the reporter drove from the north end of the overpass bridge at Ximen Station (the first ring road around the West Market) to the end of the overpass bridge at the intersection of Yangxi Road in the first ring road (Wenhua Road), about 1.3 km, and it took 15 minutes. This section is a non-construction area 100 meter, with a speed limit of 30 km/h.

The reporter pointed the way: It is forbidden to turn left around the intersection of Yangxi Road on the First Ring Road, and the speed limit of the whole construction section is 30 kilometers per hour. Pedestrians and non-motor vehicles cross the street in the crosswalk area.

At the Gaoshengqiao section of the First Ring Road, the construction scope is from the intersection of Randeng Temple East Street to Rongxing Street, about 1.2km ... Tidal traffic signs have been hung on Wuhou Temple Street. At 3 pm, a long line of cars bound for Goldman Sachs Bridge was blocked at the southwest people's gate.

The reporter pointed the way: it is forbidden to leave around the intersection of Gaoshengqiao on the First Ring Road during peak hours; Pedestrians cross the road from the crosswalks in the construction areas on both sides.

Yesterday, roads around the construction area were also affected. Under the Chengdu-Wenzhou overpass on the second ring road, it is forbidden to turn left again, and there are jams along the line. Shudu Avenue, Guanghua Avenue, Dashi East Road and Dashi West Road are relatively smooth.

The construction of the western half of the First Ring Road has also caused the increase of vehicles and the decrease of traffic capacity in the eastern half of the First Ring Road. "It took me 10 minutes to drive from an official temple on the first ring road to the provincial gymnasium." Mr. Zhou said that at the same time, he drove this road for up to 5 minutes.

"I don't know what will happen next Monday, it is likely to be a traffic jam!" Mr. Wu, a citizen who drives to work, told reporters that after experiencing the pain of traffic jam yesterday morning, he decided to check the bus lines and planned to go to work by bus or bike for the past four months.

Mr. Wu lives in Jiaotong University Road and works near Wuhou Temple. He used to drive to work, from the second ring road to the first ring road via Shawan Road, then to the intersection of Gaoshengqiao via the first ring road south, and then turn left to Wuhou Temple Street. Yesterday, he set off at 9: 30 in the morning and made a detour on Jiulidi South Road. He had to go through the construction sections of three overpass bridges, stopping and crawling all the way, and it took him almost 50 minutes to reach the intersection of Gaosheng Bridge. According to experience, the traffic volume in this area on Saturday is less than one-third of the usual working hours. "Saturday is so blocked, it is even more annoying to go to work normally." Mr. Wu said helplessly.

Chengdu East Railway Station (Shahebao Passenger Station) will be opened soon. Yesterday, the progress of Chengdu East Railway Station was released before it was officially put into use. On May 8, 20 10, Chengdu East Railway Station carried out static acceptance work; During the period from May 25th to 3rd1,joint debugging and joint test will be conducted; 2011117. Chengdu East Station will be put into trial operation, and the motor train will be put into trial operation at the lead-in line; On 2011119, Chengdu East Railway Station will be officially opened for operation.

Yesterday, the reporter learned from the Provincial Department of Transportation that due to the road inspection work in expressway, Du Ying, traffic control will be implemented on some sections of expressway, Du Ying from 9: 00 to 9: 00 tomorrow. During the period, except for construction vehicles, vehicles are prohibited from passing through the controlled sections.
