First Cast-in-Place Bridge Girder Completed on Nanxin Expressway
Workers have completed the first cast-in-place bridge girder on the Nanxin Expressway in Guangdong, China, after eight hours of continuous work.
The 50.6-kilometre expressway will link Nanhai in Foshan with Xinhui in Jiangmen and connect to existing highways.
It is designed as a six-lane road with a speed limit of 120 kilometres per hour.
The completed girder is part of a bridge ramp near the Fengming interchange and is 80 metres long across four spans.
Its construction allows crews to work on bridge foundations and columns at the same time as upper structures, which is intended to improve efficiency.
The project team plans to use this work as a model and build the remaining bridge sections in stages.
Once the expressway is complete, it is expected to shorten travel times between western Jiangmen, Guangzhou and Foshan.
The first cast-in-place box girder on the Nanxin Expressway has been completed after eight hours of continuous work.
The milestone allows construction of lower structures, such as piles and piers, to proceed alongside upper structures, including box girders.
The completed girder is on the third span of the B-ramp bridge at the Fengming interchange.
The Nanxin Expressway is a 50.6-kilometre project in Guangdong province, designed as a six-lane highway.
