The last of the roads closed for winter in Mount Rainier National Park were expected to open Thursday afternoon.
Mowich Lake Road and Sunrise Road both opened about 2:30 p.m., according to the park.
Park crews had been removing snow and debris from Sunrise in the northeast corner of the park.
Recreational vehicles and vehicles with trailers longer than 25 feet are not recommended to drive on Sunrise Road past the White River Campground intersection due to the steep, narrow, winding road.
Portions of Chinook Pass (state Route 410) and Cayuse Pass (state Route 123) opened in early June.
The Sunrise area is the second most-visited location in the park.
