Road Opening Process
Why does the road close in winter and when will it re-open for summer?
Clearing of the main park road (30 miles total), begins in April and on average takes 2 months before the road opens through. Predicting when the road will open is not possible, even in late spring, because weather in April and even May can affect plowing progress significantly. See chart below for opening and closing dates since 1980.
