According to official website's "Announcement on Bidding for Preliminary Work of Planning Project in expressway, Guangxi (20 19-2023)", in the second half of 2022, there will be 29 planned new expressway projects in Guangxi for bidding, including Luocheng-Yizhou Expressway, Yizhou-Shanglin Expressway and Nanning-North First Ring Road-Shanglin Expressway. , excluding Rong 'an-Longsheng Expressway, so I don't know, so I suggest to continue to pay attention to official website and Guangxi Provincial People's Government.
There are 7 interchanges in the expressway planning from Rong 'an to Longsheng, and the main line passes through the south of Longsheng County and Sanmen Town from north to south.
