合川位于重庆市主城区西北,幅员2356平方公里,属山岭重丘和微丘地区,全市人口151万,因嘉陵江、涪江渠江交汇于此而得名。长期以来,江河阻隔、交通不畅一直是地方经济发展最大的障碍。 1998年以前,除国道212线合川段以外,全市所有公路均为三级以下公路、等外路和泥结碎石路,投资环境较差。重庆直辖 Hechuan is located in the northwest of the main city of Chongqing, with a total area of ​​2,356 square kilometers, belonging to the mountainous and Qiuqiu areas. The population of the city is 1.51 million. The city has its name because Jialing River and Fujiang River converge here. For a long time, blocking rivers and poor traffic has always been the biggest obstacle to the development of local economy. Before 1998, except for Hechuan Section of National Highway No.212, all the roads in the city were under three levels of roads, outer roads and clay-bonded gravel roads with poor investment environment.
