Yellowstone National Park South Entrance, Yellowstone visitation

Stretch of Mammoth-Norris Road May Stay Temporarily Closed to Vehicle Travel

A portion of the Grand Loop Road between Mammoth and Norris may remain closed as other roads in Yellowstone reopen to cars and other vehicles.

According to a Yellowstone press release, due to construction on the Mammoth-Norris route—between Willow Park and Roaring Mountain—the road is currently muddy and rutted. Crews are working to improve driving conditions, but there is no guarantee the route will be ready in time for its scheduled opening.

The park did not give an estimate when the road would reopen, should the opening be delayed.

Earlier this week, we reported select roads and facilities would reopen Friday, April 20. This included the stretch of road between Willow Park and Roaring Mountain. You can see the full list of Friday road openings below, courtesy of Yellowstone:

• West Entrance to Madison
• Madison to Old Faithful
• Madison to Norris
• Norris to Canyon Village
• Norris to Roaring Mountain
• Mammoth Hot Springs to Willow Park

The road between the North and Northeast Entrances stays open year-round.

Roads will reopen from April 20 to May 25 as crews conduct spring plowing. You can see the full schedule here. Read here to see the list of opening and closing dates for Yellowstone facilities like hotels and restaurants.

UPDATE: The road between Mammoth and Norris will open as scheduled Friday, April 20. Read the full story here.
