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.

State Route 123 (SR 123) Rehabilitation

SR 123 travels north-south along the east side of the park from the southeast entrance near Packwood, WA, to the junction with SR 410 at Cayuse Pass. The rehabilitation project will work on a 2.8 mile section of SR 123 from Laughingwater Creek Bridge (milepost 2.5) to Panther Creek Bridge (milepost 5.2). The project will replace substrate to level the road, rehabilitate ditches, and replace/upsize 18 culverts.
