Outer Ring Expressway to be completed
Phase I of Shenzhen Outer Ring Expressway, the longest expressway in the city, will be put into operation before the end of the year, according to the contractor, 18th Engineering Bureau of China Railway Construction Corp.
The construction of the 93.2-kilometer expressway, a key project of Guangdong's expressway network, is being developed in three stages. It includes 76 kilometers in Shenzhen and 17 kilometers in Dongguan.
The Shenzhen section of Phase I extends 51 kilometers. It starts at the Guangzhou-Shenzhen Riverside Expressway and ends at Huizhou-Yantian Expressway, passing Bao'an, Guangming and Pingdi.
Phase II will link Huizhou-Yantian Expressway in the east and end at Jinxiu East Road. It will be 9.35 kilometers long.
Phase III will be 16 kilometers long and will link Yantian-Baguang Expressway in the east. Upon operation, the two-way, six-lane expressway designed for speeds of 80-100 kilometers per hour, will help relieve traffic pressure in the city's north that borders Dongguan and Huizhou.
In another development, the tunnel boring work on the Chunfeng Tunnel under the Chunfeng Overpass in Luohu District has progressed about 850 meters.
For the construction of Chunfeng Tunnel, the contractor has been using the largest home-grown slurry shield machine that measures 135 meters long and can dig a tunnel with a 15.8-meter diameter. The tunnel project is 5.08 kilometers long, and connects Binhe Road in the west and the Xinxiu Overpass in the east. Its underground section is 3.6 kilometers. Once operational in 2021, the tunnel will relieve congestion on the Chunfeng Overpass.
