The reconstruction project is designed according to the second-class highway standard, with a total investment of 48 million yuan, starting from Huiquan Village in Qiu Town in the east and reaching the east intersection of Zhongcun Town in the west, with a total length of 32.75 kilometers. According to the principle of "no widening, no demolition", the original road is treated with subgrade settlement, cement stabilized layer and asphalt concrete are paved, and traffic facilities along the line are installed and improved. The project officially started on August 10, and the main project was completed on August 18+05. 20 10 has been completed by the end of the year.
