• We have new information about how to best fix problem sites on SR 410. Our findings are detailed in an informational handout (http://www.wsdot.wa.gov/NR/rdonlyres/AEC2D6DC-32FF-463E-A72D-2B5873B791D8/0/SR410_folio_Dec07.pdf)(pdf 1,300kb)
• We are reviewing various design alternatives and site locations to determine the best approach and project scope.
• We finished building a model to illustrate the current state of SR 410 and its future if we don't take steps to preserve it
Overview
WSDOT implemented short-term fixes on State Route 410 near the entrance to Mount Rainier National Park. These stop-gap protection measures will slow the erosion and flooding threat posed by the White River until a long-term solution is in place by the National Park Service.
WSDOT is committed to taking comprehensive steps to save this nationally recognized Scenic Byway for future generations. The 2005 Gas Tax provides $17 million to preserve the road between Greenwater and the Mt. Rainier National Park boundary. We expect to start this work by summer 2009. The National Park Service will lead a separate effort to develop solutions for the problem sites within its jurisdiction.
Why is WSDOT planning repairs along State Route 410 just outside Mt. Rainier National Park?
The wandering White River, the force of gravity, and melting snow pack and glaciers combine to threaten a large section of SR 410 near Mount Rainier. In some areas the river is eroding and damaging the highway. In other areas the river has shown it can jump its banks and use SR 410 as a riverbed, causing heavy damage.
Steps must be taken now to protect SR 410. Recent river activity shows the high risk that the river could shift its flow to the highway. If that happens, sections of the highway may be irreparably damaged and access from the west side of Mount Rainier to Sunrise Visitor Area in the park could be lost. Access also would be threatened or severed to Crystal Mountain Boulevard, that joins SR 410 just outside the park entrance, and to nearby cabins. Travelers who rely upon SR 410 as a summer shortcut between Enumclaw and Yakima would have to add 70 miles or more to their cross-Cascades trip.
