去过黄石的朋友麻烦看看这条封路影响大不大？

打算9月底到黄石游玩，刚刚查看官网看到一条路是9月11开始封路到10月7，请问对自驾游有多大影响？

2. Mammoth Hot Springs to Norris Junction
Full closure from September 11 (starting at 10 pm) to October 7: detour over Dunraven Pass.Norris and Indian Creek campgrounds will remain open. Grizzly Lake, Solfatara, and Mount Holmes trailheads are located within the night and full closure zones and will be closed during those periods.

另外下面这是今年封路的信息
