In addition, a traffic accident occurred at K 1679 Wolong Tunnel, which is about 1 1 km from Pingliang of G22 Qinglan Expressway to Dingxi. Two-way vehicles need to enter and exit from Jingning toll station and Dashanchuan toll station temporarily, resulting in large traffic flow and slow traffic.
Therefore, the road conditions from Pingliang to Jingning are affected by maintenance construction and traffic accidents, and vehicles that need to pass should pay special attention to relevant early warning tips and road information.
