Travelers using state Route 410 to visit Mount Rainier National Park and the surrounding should allow extra time for their trip May 30-June 8, the state Deparment of Transportation announced Thursday.
Thirty-minute delays are expected 7 a.m.-5 p.m. while crews perform emergency rock slope repair about 5 1/2 miles west of Crystal Mountain Boulevard. A lane will be closed and traffic will alternate using the open lane. Crews have been working in the area since a mid-April rockslide. A barrier was placed to prevent more falling debris but a vehicle was damaged by a rock in early May.
The state is seeking emergency funds from the Federal Highway Administration to cover the estimated $800,000 cost.
The work is scheduled to last six weeks but traffic is expected to alternate through the work zone more frequently after June 8.
