Original title: Beiqing Road cross-Beijing-Tibet four-story interchange began construction and rapid transformation will ease the congestion of the Fifth and Sixth Ring Road
A four-story fully interoperable overpass will be erected on the “overhead” of the Beijing-Tibet Expressway. On October 19, the much-watched Beiqing Road rapid transformation project made new progress-Beiqing Road crossed the Beijing-Tibet Interchange and began to enter the site for construction. After the completion of this large interchange, residents in the northern urban area can go directly to the east and west through the overpass. In all directions from the north to the south, the current congestion at the Xinzhuang Bridge of the Beijing-Tibet Expressway during the peak period is alleviated. According to the plan, the first phase of Beiqing Road’s rapid transformation project will be completed in September 2024, which will relieve the congestion on the North Fifth and Sixth Ring Road and improve the traffic efficiency of the road network in the “Huitian” area.
The scale of the cross-Beijing-Tibet interchange is equivalent to the Xizhimen Bridge
On the morning of October 18, it was seen at the construction site that the Beiqing Road Crossing Beijing-Tibet Interchange Project had begun the construction of the bridge substructure. With the cooperation of the crane, the workers carried out the hoisting of the platform template and the binding of the bridge pier column reinforcement.
The scale of this four-story interchange is equivalent to the Xizhimen Bridge, and it is also a major difficulty in the renovation project. “The four-story structure of this interchange has a highest point of 25 meters, with 10 ramp bridges, and there are as many as 10 intersections between the bridges. However, citizens will not feel going around when they drive in the future.” According to project manager Guo Shui, the difficulty of the project is also reflected in the construction of the newly built subway under 4 times, 6 times on the highway, and the construction of road and bridge pipelines at the same time. It is difficult to organize and coordinate. It is necessary to ensure the safety of the subway and high-speed traffic in operation through precise planning. .
At present, the morning peak congestion at Xinzhuang Bridge on the Beijing-Tibet Expressway can last from 7:00 to 10:00, with a passing time of up to half an hour. In the future, with the completion of this interchange, citizens can use various ramp bridges to switch to east, west, south and north directions, without having to block under the bridge and waiting for signal lights, and the bridge area’s traffic capacity will be greatly improved. According to reports, after the completion of the future construction, the location of the Beijing-Tibet Expressway toll station will also be relocated in conjunction with the use of the new building.
It is understood that in addition to the start of construction across the Beijing-Tibet interchange, a large area of the east of Huichang East Road has also been entered in a large area, and the construction of underground pipelines and planned municipal pipelines are being demolished.
The first phase intersects with two high-speed 4 main roads
From the map, the rapid transformation project of Beiqing Road runs from east to west, starting from Youyi Road on the west side of Jingxin Expressway in the west, to Jingcheng Expressway in the east, passing through Haidian District and Changping District, with a total length of 19.4 kilometers. Among them, the first phase of the project from Youyi Road to Hongfu West Road is about 8.9 kilometers long. In addition to crossing the Beijing-Tibet Expressway, an interchange will also be set up on the Jingxin Expressway.
Beiqing Road is planned as an urban expressway, with a red line of 60 to 110 meters wide, with a rapid viaduct above it and a ground auxiliary road below it. The standard section is two-way 6-lane.
“Along the first phase of the project, there are a total of 6 intersecting roads, including the two expressways of Beijing-Xinjiang and Beijing-Tibet, and four main roads of Erbozi West Road, Huichang East Road, Zhanqian Street, and Hongfu West Road. Intersecting and adjacent to major railways There are 4 tracks in total, including Beijing-Zhangjiakou High-speed Railway, Northeast Ring Railway, Metro Changping Line, Metro Line 8, and it also intersects with 6 rivers.” Zhang Dong, on-site director of Beiqing Road Rapid Transformation Project of Shoufa Group Gonglian Company According to the introduction, the main road from Jingxin Expressway to Qiyan Road adopts the form of viaduct. The viaduct is about 4.78 kilometers long. The terminal main road crosses Hongfu West Road at a level. The conditions for setting the viaduct on the Hongfu West Road in the long term are reserved. The project implements municipal public pipelines, greening, transportation, lighting and other projects simultaneously with the roads.
The commuting efficiency along the route is expected to increase by 1.2 to 1.8 times
Beiqing Road is the main east-west traffic artery between the North Fifth Ring Road and the North Sixth Ring Road. It is an important municipal expressway connecting Haidian, Changping, Shunyi and other areas.
“The construction of the project will effectively reduce the traffic pressure on the Fifth and Sixth Ring Road. At the same time, as an important horizontal expressway in the northern region, it connects the high expressway network in the northern region, further strengthens the connection and conversion between the Northwest Passage and the Northeast Passage, and strengthens Haidian, The connection between the three districts of Changping and Shunyi improves the traffic efficiency of the road network in the Huitian area, and promotes the connection between the Zhangjiakou, Yanqing, and Changping districts and the sub-centers.” Zhang Dong introduced.
According to preliminary estimates, after the road is completed and opened to traffic, the commuting efficiency along the route is expected to increase by 1.2 to 1.8 times.
In order to minimize the impact on the life and travel of surrounding residents, the project will adopt continuous road construction, reasonably set up traffic guidance, and guide citizens to pass normally during the construction period through remote prompts and signs and markings. (Sun Hongyang)
