Overpass in Yunyan district makes progress

The main structure of the an overpass along the Zhonghuan Road -- the extension of Yan'an East Road in Yunyan district in Guiyang, capital of Southwest China's Guizhou province -- was recently closed, taking it one step closer to the smooth opening of the Yan'an East Road extension.

The overpass has six ramps with a total length of 2,672.4 meters and a standard width of 8 meters, as well as three pedestrian underpasses and four bridges. Its contractor is Zhongyuan Construction Group.

As a key municipal project for Guiyang, the extension of Yan'an East Road project is a top priority for the company.

During the construction, the company overcame safety and stability control challenges posed by the high support formwork body, caused by the high bridge height and the large longitudinal slope.

The extension of Yan'an East Road has a total length of 3,110 meters and has a two-way eight-lane asphalt surface.

The construction content includes road engineering, a bridge and culvert and a tunnel, as well as auxiliary projects including drainage, lighting, traffic safety, and management facilities and greening.

After completion, it will substantially improve the efficiency of regional traffic.
