Highway brings relief to Hongqiao
Print Edition
A new elevated highway section will open today to connect the city’s north Jiading District and Hongqiao Traffic Hub, while also relieving traffic congestion in the Hongqiao area, officials said yesterday.
The 6.8-kilometer-long northern section of the Jiamin Elevated Road will cut the driving distance between Jiading New City and Hongqiao Business District by half to 15 minutes.
From today, drivers from Jiading will also be able to reach the Xinzhuang area in Minhang directly via the elevated road, the district government said.
The newly open section between the G2 and S6 expressways has six lanes in two directions with speed limits of 80 kilometers per hour. It spans across Jiangqiao, Nanxiang and Malu towns as well as Yunzaobang Creek.
The Jiamin Elevated Road currently stretches for about 36 kilometers through Jiading, Qingpu, Songjiang and Minhang districts as well as providing a main passage between the Hongqiao hub and Shanghai’s western outskirts.
Once fully completed, the road will serve as a south-north expressway between the Outer Ring Road and Shenhai Expressway to alleviate the busy vehicle flows of the Hongqiao traffic hub and the west section of Outer Ring Road, according to the Shanghai Road Administration Bureau.
Regarding today’s new section, prefabricated highway construction was used for the first time in the city to help to reduce air pollution and noise from construction sites, said the Shanghai Municipal Investment Group Highway Co, the major builder for the new section.
Construction workers simply assembled the parts. Only the supporting structures, such as the bearing walls, were built on site. The new skills required for the prefabricated parts will be called upon for infrastructure constructions across the city.
Prefabrication can reduce the construction schedule by an average 10 percent as well as cutting the labor force needed by 30 percent, an official with the group said.
Prefabrication helped to push forward the latest highway section completion by three months, the official said.
The new method is set to be applied to the city’s under-construction S7 highway and Beiheng Passage, a 19.4-kilometer thoroughfare linking Changning, Jing’an, Putuo, Hongkou and Yangpu districts.
