Yellowstone's East Entrance is scheduled to open to travel on Friday, May 1st. The park's South Entrance is set to open to the following Friday, May 8th.
Construction is under way north of the entrance to the Norris Campground on the road to Mammoth Hot Springs. Crews are rebuilding a 5.4 mile section of the road, as well as the bridge over the Gardner River. Visitors should expect daytime delays of up to 30 minutes throughout the summer season. Crews are also replacing the Isa Lake Bridge, which is on the road between Old Faithful and West Thumb Junction. This section of road will open June 11, with up to 30 minute traffic delays.
Details on both of these projects and updated Yellowstone National Park road information is available 24 hours a day by calling 307-344-2117, or on the park's website.
Very limited visitor services will be available during the next several weeks. For updated information, click here, or consult the park newspaper available at the entrance station.
Visitors should be aware that spring in Yellowstone is unpredictable and often brings cold temperatures, high winds and snowfall. Travelers should use caution as road-clearing operations may be occurring at any time throughout the park. In the case of extreme weather conditions, temporary road closures are also possible with little or no advance warning.
