Yellowstone National Park, Grand Teton National Park & Region
All park roads are open for the 2018 summer season!
The road between the North Entrance (outside Gardiner) and the Northeast Entrance (serving Silver Gate and Cooke City) remains open all year.
Due to construction between Willow Park and Roaring Mountain, visitors should expect delays of up to 30 minutes along the Mammoth-Norris road. Visitors should also expect delays of up to 30 minutes around Fishing Bridge due to construction.
The Beartooth Highway, which connects the Northeast Entrance to Red Lodge/Billings, Montana, also opens May 25, weather permitting.
The Importance of Knowing Yellowstone Road Conditions
Navigating Yellowstone National Park is both simple and complicated. It’s simple in one sense in that the main road, the Grand Loop, provides access to all services inside the Park, and the simplicity of the road plan makes it highly unlike you’ll get lost. On the other hand, given the long stretches of road between services, you’ll want to plan ahead, as it takes some time to get around (the posted speed limit is 45 MPH, and that limit is certainly enforced by Park officials), which makes a knowledge of Yellowstone road conditions so important. At this time of year only part of the Park is open to road traffic, while plows groom the roads in the rest of the Park for snow coaches and snowmobiles in coming weeks.
