From Guazhou to Dunhuang, why not take the provincial highway and take high-speed navigation? Can't you leave?

Hello, I'm Master Jiang from chartered flight, a northwest tourist. Expressway from Guazhou to Dunhuang was completed and opened to traffic in August this year. The dart runs parallel to expressway. The road on the right hand side of expressway is the provincial highway, which is very close to the toll station, so people generally don't pay much attention to the distinction.

I hope I can help you!
