Weather-dependent work begins Wednesday, Feb. 21
MOUNT RAINIER – Travelers planning to visit the Crystal Mountain Ski Area via State Route 410 should prepare for traffic delays beginning Wednesday morning, Feb. 21.
Washington State Department of Transportation maintenance crews must perform emergency work to repair an eroding river bank below the eastbound lane of SR 410, located about five and a half miles west of Crystal Mountain Boulevard. Both directions of traffic will alternate through a single lane for approximately two and a half weeks during this weather-dependent work.
People who travel by car or bicycle should prepare to wait approximately 30 minutes between the hours of 7 a.m. and 4:30 p.m. on weekdays between Wednesday, Feb. 21, and Friday, March 9. Both lanes will remain open on the weekends. Emergency vehicles will have access during the closure.
“Crews will do their best to shorten how long travelers need to wait during the morning and afternoon peak travel times,” said Assistant Regional Administrator Dave McCormick. “However, we do expect traffic on the highway to be heavier as local schools are on mid-winter break and more visitors are expected at the resort.”
Emergency repair work
WSDOT maintenance crews noticed the bank erosion for the first time during routine culvert inspection on Wednesday, Feb. 7.
engineers assessed the slope on Thursday, Feb. 8, and determined an immediate fix is necessary before soil washes out under the edge of the highway.
During the closures, crews will use large cranes to place wood, well-graded rock and large boulders along the base of the slope, adjacent to the White River. This will strengthen the slope in order to protect the highway.
