Extended data

Yibi Expressway is connected with Zhenbi Expressway under construction and Hezhen Expressway to be built soon through Zhenxiong Interchange. Interchange adopts the form of variant alfalfa leaves, which mainly solves the traffic flow conversion between Zhenbi Expressway and Hezhen Expressway. The interchange is a hub interchange, and the interchange is located between the main toll station of Zhenbi Expressway and Zhangjitun Tunnel.

The construction of Zhenxiong Interchange will effectively reduce the traffic pressure of Zhenxiong, which is of great significance to realize "unblocked Zhenxiong" and promote the rapid economic development of Zhenxiong County.

The construction of Zhenxiong Interchange in Fenghuang Net-Yibi Project is busy.

Public Network-Three expressways in Zhaotong, Yunnan will be opened to traffic this year.
