Why is Zibo called an expressway instead of an elevated road?

Because Zibo Expressway has achieved rapid traffic, it is called expressway.

Zibo Expressway is basically elevated. Although it is elevated, it is still called expressway in order to be more rigorous and highlight its characteristics.

The expressway viaduct between Yuanshan Avenue and ground road (Xincun Road-Maying Interchange) and Jinjing Avenue in the first phase of Zibo Urban Expressway Network was opened to traffic in the early morning of August/KLOC-0, and Zibo officially entered the "elevated era".
