Chinook, Cayuse passes open for season

The passes on State Route 410 and State Route 123 reopened Tuesday after crews cleared spring snow. A construction project will cause additional delays through June.

Cayuse Pass on State Route 123 and Chinook Pass on State Route 410 reopened to traffic Tuesday after its annual winter closure.

The delayed opening was due to heaving spring snowfall and a significant construction project to repair a quarter mile of SR 410 near milepost 64 along Mather Parkway in Mount Rainier National Park.

Road repairs will continue through the end of June, and travelers should expect delays with alternating one-way traffic over a half mile stretch at milepost 64.
