The section from the Rotunda of Bad Liyuan in the south of Xuchang to Xu Fan has been paved with oil. National Highway 3 1 1 prohibits trucks from leading to Yongchang Avenue, and the southern outer ring of Liyuan is bypassed by Xin 107. In the north, large trucks in the west outer ring are prohibited from passing to Yongchang Avenue. Large trucks bypass G240 National Road, and perhaps Changnan Outer Ring hopes that this plan can be passed quickly. Give Xuchang citizens a safe way to travel.
