Most of the roads inside Yellowstone National Park will soon be no longer accessible to motor vehicle traffic.

The West, South and East entrances to the park, are scheduled to close to motor vehicle traffic on Monday, November 7th, for the 2016-17 winter season.

If there's enough snowfall, the park is scheduled to reopen the West and South entrances to snowmobile traffic on December 15th, and the East entrance on December 22nd.

Only the North and Northeast entrances will remain open to motor vehicle traffic, weather permitting, so that motorists can travel between Gardiner and Cooke City, Montana.

Snowplow crews won't start clearing the closed snow covered highways until around middle-March of 2017, and motor vehicle traffic won't be allowed back into the Park until sometime between middle April and middle May, depending on which entrance to the park is used.
