How to get from Baoding to Zhangjiakou after the opening of Zhangshi Expressway? From which port does Shijiazhuang Expressway need to be stretched?

Now it's from Xiling, Yixian County to Laiyuan, so to get to Zhangjiakou, you have to take G5 (Beijing-Kunming Expressway) to Yixian County, then turn west and go north after Laiyuan. Actually, it's quite a detour As shown in the following figure

Answer to supplementary question: The whole line is open to traffic, and the original Zhangshi Expressway was designed in this way. In the future, Laiyuan has plans to go south to Shijiazhuang directly, but even the specific route has not yet been decided!
