China’s longest tunnel cluster - Hangzhou Zi-Zhi tunnel was officially opened. SUPCON has undertaken its mechanical and electrical installation section.
With a whole length of 14.1 kilometers, the tunnel starts from the south bank of Qiantang river and ends in the north of Zijingang Road. The whole line is composed of 3 tunnels and 2 bridges and culverts.
Now, citizens from the south to the west and north of Hangzhou can take the shortcut by this tunnel and save at least half an hour on road. At the same time, transit vehicles in the scenic spots also get shunted in this way.
