Beijing's East Sixth Ring Road Renovation Project Opens to Traffic

Recently, the renovation project on Beijing's East Sixth Ring Road (from Beijing-Harbin Expressway to Luyuan North Street) undertaken by Beijing Urban Construction Survey and Design Institute (BUCSDI for short), a subsidiary of UCD, has been opened to traffic upon full completion, which is of great significance to promoting the coordinated development of transportation in the Beijing-Tianjin-Hebei region, building Beijing’s comprehensive transportation system, and improving the transportation services of Beijing's sub-center.

The reconstruction section of the East Sixth Ring Road serves as a crucial passage connecting Shunyi, Daxing, Yizhuang, Beijing Capital International Airport and Beijing Daxing International Airport. It spans about 16.3 kilometers, starting from the Beijing-Harbin Expressway Interchange in the south and ending at Luyuan North Street in the north. With a designed speed of 80 kilometers/hour, this section has been widened from the present two-way four-lane road to a two-way six-lane road and is divided into a ground extension section and an underground renovation section. The subgrade widening section has a length of 7.1 kilometers and the tunnel section is approximately 9.2 kilometers long. It has a 7.3-kilometer-long shield tunnel, which has been the longest shield expressway tunnel in China.

During this reconstruction project, BUCSDI, a leading enterprise in the field of smart survey of urban infrastructure, gives full play to the collaborative advantages of multiple disciplines such as survey, measurement, monitoring, geotechnical engineering, and informatization by providing professional technical services including engineering survey, engineering measurement, and safety monitoring and geotechnical design, ensuring the safety of the project structure, engineering and surrounding environment, thereby contributing to the high-quality completion of the project mentioned above.

The original East Sixth Ring Road passes through Beijing’s sub-center in the north and south direction. The expressway divides the city into two large areas. Introducing the original road underground through transformation will eliminate the fragmentation impact on the sub-center space and boost the integration of Tongzhou District and the administrative office area of Beijing’s sub-center. The 12 planned roads and 5 current roads on the east and west sides of the sub-center will be unblocked in the east-west direction, which will effectively build a comprehensive transportation system and promote coordinated transport development in the Beijing-Tianjin-Hebei region. Besides, the original site selection will be transformed into the world's largest high line park, offering citizens more leisure space.
