way of a diamond interchange. SR 162 travels north into Downtown Sumner as Valley Avenue and south over the Puyallup River towards Orting. The freeway section near the interchange was the busiest recorded part of SR 410 in 2008 with a daily average of 59,000 motorists using the freeway. Continuing northeast, SR 410 connects to 166th Avenue and turns southeast as an undivided highway into the community of Bonney Lake. East of Bonney Lake, the roadway heads east, passing two shopping centers before entering Buckley and intersecting SR 165. In Buckley, the street travels northeast through Downtown and turns north to cross the White River and enter King County. After leaving Pierce County, the highway travels northeast through rural areas into Enumclaw and passes Enumclaw High School before turning east and being renamed Roosevelt Avenue. As Roosevelt Avenue, the street intersects Griffin Avenue, also designated SR 164, which travels northwest to SR 169 and Auburn. The roadway, now named the Chinook Scenic Byway, passes by the King County Fairgrounds and Enumclaw King County Park. Leaving Enumclaw in a southeastern direction, SR 410 begins to parallel the White River upriver into Federation Forest State Park, a state park consisting of old growth evergreen forests. The highway crosses the Greenwater River, northeast of its confluence with the White River, and re-enters Pierce County. The bridge ends in the community of Greenwater, named for the river, where the roadway encounters Forest Road 70, which has been proposed to become SR 168 over Naches Pass as an alternative to the Chinook Scenic Byway. From Greenwater, the road travels south alongside the White River into Mount Baker-Snoqualmie National Forest, passing Ranger Creek State Airport, a state-owned airport that is open in the summer and early fall. The byway travels south into Mount Rainier National Park. SR 410 is closed at the gate to Morse Creek, about 5 miles east of the Chinook Pass Summit during the winter and early spring due to high wind, limited cell service and avalanche danger. It intersects SR 123 at Cayuse Pass. SR 410 turns east at the intersection and heads through a series of hairpin turns, passing Tipsoo Lake, to Chinook Pass. Chinook Pass is the border between Pierce and Yakima counties and Mount Rainier National Park and the Wenatchee National Forest. The pass is also where the highway crosses the Pacific Crest Trail, a National Scenic Trail that
