Why doesn't Baixin Expressway go to Xinning County?

If there are repairs, only Huilongsi Town will be built in the first stage (it is expected to be open to traffic in April and May 2023), and Huilongsi Town is the intersection of two expressways. The follow-up Xinxin Expressway will be opened to traffic in 2027, from Xinhua County to Huilongsi Town Hub via Longhui County, one to Dong 'an County and the other to Xinning County. There are two reasons for going to Huilongsi Town in the first stage. The first is that Huilongsi Town is the northernmost gateway of Xinning County, and entering Huilongsi Town is equivalent to entering Xinning County; The second reason is that the road demolition from Huilongsi Town to Xinning County is a slow process. From the map of Gaode, the route has been planned, and a large number of residential buildings have not been relocated at many points.
