New-built ramp ring road on Kuangshan Overpass opens to the traffic

　　The new-built double-way ramp road on south and north side of the west bridge of Kuangshan Overpass opens to the traffic on July 16th . The grounding part will be dismantled recently after the close construction of the west bridge. Then 120-meter-long box girder will be jacked up about 4.2 meters, connecting the new west extension section of Beiyuan Viaduct and Kuangshan Overpass.
