Overhaul of Songpu Bridge begins on Monday
By:Wu Qiong  |  From:english.eastday.com   |  2017-09-29 09:05

With the removal of a steel track on its lower deck, the overhaul of Shanghai’s Songpu Bridge officially kicked off on Monday, September 25. The 41-year-old bridge in Songjiang District will undergo a comprehensive maintenance and renovation during the next couple of years.

According to Chen Liang, chief engineer of the Bridge Design Institute of the Shanghai Municipal Engineering Design Institute (SMEDI), while the main structure of the double-decked bridge is kept, the bridge’s upper deck will be widened. Four lanes will be added to turn the deck into a six-lane road. The upper deck, which was an abandoned rail bridge, will be put into use again and be converted into a space set aside for non-motorized vehicles and pedestrians, but the original railway elements will be maintained to highlight a theme of slow life.

As Chen Liang told the Labor Daily, to carry the additional load of vehicles, a mixed material that contains steel and concrete will be utilized, instead of using the original type of construction material.

In addition, the lower deck will be lifted by 20 centimeters, so as to facilitate the navigation of ships on the Huangpu River. 

Completed in June 1976, the Songpu Bridge is not only the first bridge over the Huangpu River in Shanghai but also the only double-decked bridge for highway and railway over the river.
