Original title: Five bridges and a closed loop road link
With the opening of the Jiangxinzhou Yangtze River Bridge (Fifth Yangtze River Bridge) and the completion of the Youfang Bridge Main Interchange Line of the Ningma Highway Reconstruction and Expansion Project, and the completion of the reconstruction and expansion project From 312 Longhua National Highway to Zhangdian, Nanjing Ring Road was officially closed. In the future, no matter where they are in Nanjing, citizens will only need to enter the city expressway, and both ends of the ring road will be accessible within an hour. At this point, Nanjing’s “two highs and two fast” urban road network offices have basically taken shape.
“As early as 1992, at the beginning of the construction of the Dongyangfang to Liucun section of the ring road, the plan for the ring road was put in Nanjing.trafficThe department’s agenda. Hu Bo, deputy director of the Nanjing Highway Development Center, told reporters. By the 1980s, Nanjing Transportation had established a “three latitude eight” spatial pattern. In the 1990s, the Jiangnan part of the ring road around the city was built. With the formation of the “fine” urban expressway, the rapid inner ring of Nanjing was closed. In 2003, the Baguazhou Yangtze River Bridge (the second Yangtze River Bridge) was completed, and Nanjing’s great traffic pattern of “one network in the city and one ring outside the city” was initially formed. Traffic across the river remains the bottleneck for ring road traffic. To solve the problem of cross-border traffic, the Dashengguan Bridge on the Yangtze River (Third Bridge on the Yangtze River) and the Qixiashan Yangtze River Bridge (Fourth Bridge on the Yangtze River) have been completed and opened to traffic and opened to traffic, forming the Ninghuai Expressway and the Ring Road. The traffic circuit of the outer ring of the ring road is completely closed. However, at that time, the fifth bridge over the Yangtze River and the Jiajiang Bridge that crosses the Puyi Expressway had not yet been built. The ring road can only cross the river via the third bridge. The Jiangbei Express Loop Line was not closed effectively.
Although the high-speed ring road around the city was closed, the Nanjing Department of Transportation further accelerated the construction of the ring road around the city. Since 2012, the transportation department has carried out a rapid transformation of Jiangbei Avenue.BuildingSupported the main skeleton of the Jiangbei region. Starting in 2015, the construction of the Jiangxinzhou Yangtze River Bridge (5th Yangtze River Bridge) and the Shangba Jiajiang Bridge (Puyi Road) began. At the same time, the Ningma Highway Youfang Bridge Interchange and the 312 Longhua to Zhangdian National Highway Axis Expansion and Reconstruction Project were also built simultaneously. , Ring Road Ring Road closed officially. At present, all the mentioned projects are finished and have the conditions to be open to traffic. Together with the Baguazhou Yangtze River Bridge (the second Yangtze River Bridge), Ring Road and Jiangbei Avenue, they form the Nanjing Ring Road.
Ring Road Ring Road and Ring Road Ring Road connect more than tenhighwayThe connection to the grid has effectively alleviated the traffic pressure in the city, and also created a good traffic infrastructure for the development of Nanjing and the further development and improvement of the Jiangbei New District, Hexi New Town, the New South City, Banqiao New Town and Kylin Science and Technology Ecological Park.

In addition to the five bridges around the city, two main nodes have also been opened
In addition to the 5th Yangtze River Bridge and the Shangbajiajiang Bridge on the Puyi Expressway, there are also two key nodes that have just been completed on the Ring Road. They are the main line of Youfang Bridge interchange in Ningma Highway and 312 National Highway Reconstruction and Expansion Project. Longhua to Zhangdian Expansion and Reconstruction Project. Yesterday, the reporter came to these two places to understand the construction situation.
Youfang Bridge, the largest interchange in Nanjing history:
The main line and some ramps have been opened.
The main line of the Ningma Expressway Youfang Bridge interchange was completed and opened, and the four ramps connected to the fifth bridge were opened to traffic. Among them, the HR ramp from Baguazhou Bridge (Second Bridge) to Fifth Bridge was opened to traffic.
After the completion of the reconstruction and expansion of the Youfang Bridge Interchange, there will be 17 ramps, making it the largest interchange in Nanjing history. It not only forms a fast circular line that crosses the river with the Ring Road and the five bridges, but also connects Fengtai South Road, Hongyun Avenue, Longxiang Avenue, Ring Road, Ningma Expressway, the Fifth Yangtze River Bridge and Jiangshan within from the reach of Nanjing. The 7 highways of the main street are related to the travel of millions of citizens in the Daishan and Hexi Jiangshan Main Street areas. The traffic flow shows that 142,000 vehicles go through the intercom every day, and 88,000 of them use the intercom to change direction.
On the road around the city, Youfang Bridge has always been a blocking point. At the design stage of this renovation, the Municipal Transportation Bureau scientifically analyzed the causes of the congestion and found that the main point of congestion was a 200 meter “interlocking section” within the Youfang Bridge interchange. Traffic flow From the ring road main line to Sanqiao direction and Fengtai South road to Sanqiao ramp is 200 meters away.AgreementOrganization, resulting in a normalized congestion, greatly reducing the efficiency of highway traffic around the city After the completion of the Youfang Bridge expansion next year, the cancellation of the interlocking section will effectively relieve congestion standardized. From Hexi, Daishan and Banqiao New City to the urban area via the city’s ring road, you can save about half an hour during the morning and afternoon peaks.
Project manager Chen Xiaoning told reporters that to allowWorking hoursThe impact on citizens was minimized and the Municipal Transportation Bureau repaired 12 roads in Baotong. Currently, the main interconnection line has been completed and the rest of the project will be completed before the end of 2021.
312 National Highway Reconstruction and Expansion Project:
Main line through
At the viaduct of the National Highway 312 Reconstruction and Expansion Project from Longhua to Zhangdian, the six-lane two-lane highway is clean and flat, with new markings, and ready for traffic. Project leader Wang Qiang told reporters that the entire project is 6.92 kilometers long, of which 4 kilometers from the Wuli Bridge to Longhua are an important part of the city’s ring road.
In the past, the Ninghe Expressway 312 national highway between Longhua and Zhangdian was a “mound road”, which was like a wall above the ground, cutting the central area of Pukou district in two parts, making it difficult for residents travel between north and south. You need a lot of detours. The reconstruction and expansion project removed the mounds, built a 5,068 km viaduct and 3 interchanges, which greatly optimized the structure of the road network in the Jiangbei area. Once the main line is passed, residents of the central area of Jiangbei New Area and Pukou District can save 15 minutes on the expressway.Proyect PlanThe entire line will open to traffic in 2021.
The project is also the recycling of construction waste in the provinceindustryThe Benchmarking Project. During the demolition of the old roads, the project will demolish 115,000 cubic meters of various construction materials such as asphalt pavement, cement blocks and old bridges.BuildingA high-level green recycling base,ScrapDivided into four main categories for processing and recycling, it has become the largest area and the most comprehensive supporting facilities in Nanjing.productThe most abundant recycling base. In 2020, it is estimated that the production capacity of recycled waste materials will reach 800,000 tons. After the project is completed, the base will continue to function. It can produce around 800,000 tons of various types of recycled materials each year, generating 10 million yuan ofprofit, Reduce carbon emissions by 260,000 tons per year, boosting Nanjing’s green development.
