Park Construction

 

Mount Rainier National Park has several ongoing construction projects on park roads, buildings, and campgrounds to enhance safety, accessibility, and the visitor experience. Due to high amounts of snowfall during the winter, most of this work must occur during the short summer season. Stay informed about potential impacts to ensure a smooth and enjoyable visit to the park. Check back regularly for updates.
