Dapu Expressway is an important part of the expressway from Beiliu City to Pingxiang City in the "Guangxi Zhuang Autonomous Region Expressway Network Planning (2018-2030)", and it is a key project of the autonomous region's major transportation infrastructure construction planning. The main line of the expressway has a total length of 123.7 kilometers and passes through Liangqing District of Nanning City, Qinbei District of Qinzhou City, Lingshan County and Pubei County. After the project is completed, it will become the most convenient new expressway between Nanning and the Pearl River Delta region. From Nanning to Guangdong via Dapu Expressway, the journey is shortened to more than 3 hours, and the time is reduced by nearly half.
