On May 31, 2022, the Guiyang-Huangping Highway is opened to traffic
One of the key projects—Yangbao Mountain Bridge
Within the Ganxi National Forest Park, after optimizing the plan for the Yangbao Mountain Bridge, vegetation damage was reduced by more than 90%. At the entrance of Jiaduo Tunnel, in order to protect a hundred-year old pine, the project put the pine in the green belt in the middle of the highway and took good care of it, avoiding relocation and destruction of it, creating a unique sightseeing spot. Through various measures such as zero excavation at the tunnel entrance, site-specific gravel-soil-taken field and spoil ground, green design optimization, reclamation, the whole line has saved more than 600 mu of land and relocated and protected thousands of rare trees.
Connecting Guiyang to Huangping, its main line is 120.6 kilometers long with a design speed of 100 kilometers per hour and six lanes. The Guiyang-Huangping Highway includes 80 bridges and 14 tunnels, with the ratio of bridges and tunnels exceeding 40%. The key projects include three bridges and four tunnels and two interchanges. The Guiyang-Huangping Highway's opening to traffic, has not only effectively improved the highway traffic network in the southern and southeastern region of Guizhou Province, and become the most convenient high-speed channel for Guiyang to reach the Yangtze River Delta Economic Zone. It will further improve the highway network in Guizhou Province.
